The revised and expanded Data and Analytics Dictionary

The Data and Analytics Dictionary

Since its launch in August of this year, the peterjamesthomas.com Data and Analytics Dictionary has received a welcome amount of attention with various people on different social media platforms praising its usefulness, particularly as an introduction to the area. A number of people have made helpful suggestions for new entries or improvements to existing ones. I have also been rounding out the content with some more terms relating to each of Data Governance, Big Data and Data Warehousing. As a result, The Dictionary now has over 80 main entries (not including ones that simply refer the reader to another entry, such as Linear Regression, which redirects to Model).

The most recently added entries are as follows:

  1. Anomaly Detection
  2. Behavioural Analytics
  3. Complex Event Processing
  4. Data Discovery
  5. Data Ingestion
  6. Data Integration
  7. Data Migration
  8. Data Modelling
  9. Data Privacy
  10. Data Repository
  11. Data Virtualisation
  12. Deep Learning
  13. Flink
  14. Hive
  15. Information Security
  16. Metadata
  17. Multidimensional Approach
  18. Natural Language Processing (NLP)
  19. On-line Transaction Processing
  20. Operational Data Store (ODS)
  21. Pig
  22. Table
  23. Sentiment Analysis
  24. Text Analytics
  25. View

It is my intention to continue to revise this resource. Adding some more detail about Machine Learning and related areas is probably the next focus.

As ever, ideas for what to include next would be more than welcome (any suggestions used will also be acknowledged).

Ever tried? Ever failed?

Ever Tried? Ever Failed?

Regular readers may recall my March 2017 article [1] which started by exploring failure rates of Big Data implementations. In this, amongst other facts, we learnt that between a half and two-thirds of a range of major business transformations fail to deliver lasting value [2]. After recently reading a pair of Harvard Business Review articles from back in 2016 [3], I can also add Analytics. Here is a salient quote from the second article:

Only a little more than one in three of the three-dozen companies that we studied met the objectives of their analytics initiatives over the long term. Clearly, driving major innovations with analytics was harder than many executives expected.

Once more we see what appears to be a fundamental constant emerge, around 60% of most major business endeavours cannot be classified as unqualified successes. I feel that we should come up with a name for this figure and ideally use a Greek letter to denote it, maybe φ which is as close to “F” for failure as the Greek alphabet gets [4].

Unbalanced C-suite

The authors based their study on a 20 years of research spanning 36 client companies. The drew a surprising conclusion:

Efforts to adopt analytics upset the balance of power in the C-suite, and this shift often had a negative impact on analytics initiatives.

As ever (and as indeed I concluded in my previous article) reasons for failure have little to do with technology and everything to do with humans and how they interact with each other. This is one of the reasons I get incensed by Analytics teams saying things like “the business didn’t know what they wanted” or “adoption wasn’t strong enough” when their programmes fail.

For a start, Analytics is a business discipline and the Analytics team should view themselves as a business team. Second, to me it is pretty clear that a core activity for such teams is working with stakeholders to form an appreciation of their products or services, their competitive landscape, the markets they operate in, their day-to-day challenges and, on top of all this, what they want from data; even if this requires some teasing out (e.g. spending time shadowing people or using mock-ups or prototypes to show the art of the possible). Also Analytics teams must take accountability for driving adoption themselves, rather than assuming that someone else will deal with this, or worse, that “if we build it, they will come” [5].

Handshake

The C-suite aspect is tougher, but in my own work I try to spend time with Executives to understand their world views and to make sure I align what I am doing with their priorities. Building relationships here can help to reduce the likelihood of Executive strife impacting on an Analytics programme. However, I do also agree with the authors that the CEO has a key role to play here in ensuring that his or her team embrace becoming a data-driven organisation, even if this means changes in roles and responsibilities for some.

I’d encourage readers to take a look at the original HBR material, it contains a number of other pertinent observations above and beyond the ones I have highlighted here. When either looking to prevent issues from arising, or trying to mitigating them once they do, my article, 20 Risks that Beset Data Programmes, can also be a useful reference.

Beyond this, my simplest advice is to always remember the human angle in any Analytics programme. This is more likely to determine success or failure than technical excellence, or embracing the latest and greatest Data Visualisation or Analysis tools [6].

No doubt φ can be shown to be a transcendental number that can be linked to π, e and i by some elegant formula.

Rather annoying φ is already the label we attach to the Golden Ratio, or (1 + √5)/2, but maybe I can repurpose this as I did π back in A quantised approach to formal group interactions of hominidae (size > 2).

Predictions about Prediction

2017 the Road Ahead [Borrowed from Eckerson Group]

   
“Prediction and explanation are exactly symmetrical. Explanations are, in effect, predictions about what has happened; predictions are explanations about what’s going to happen.”

– John Rogers Searle

 

The above image is from Eckerson Group‘s article Predictions for 2017. Eckerson Group’s Founder and Principal Consultant, Wayne Eckerson (@weckerson), is someone whose ideas I have followed on-line for several years; indeed I’m rather surprised I have not posted about his work here before today.

As was possibly said by a variety of people, “prediction is very difficult, especially about the future” [1]. I did turn my hand to crystal ball gazing back in 2009 [2], but the Eckerson Group’s attempt at futurology is obviously much more up-to-date. As per my review of Bruno Aziza’s thoughts on the AtScale blog, I’m not going to cut and paste the text that Wayne and his associates have penned wholesale, instead I’d recommend reading the original article.

Here though are a number of points that caught my eye, together with some commentary of my own (the latter appears in italics below). I’ll split these into the same groups that Wayne & Co. use and also stick to their indexing, hence the occasional gaps in numbering. Where I have elided text, I trust that I have not changed the intended meaning:
 
 
Data Management

Data Management

1. The enterprise data marketplace becomes a priority. As companies begin to recognize the undesirable side effects of self-service they are looking for ways to reap self-service benefits without suffering the downside. […] The enterprise data marketplace returns us to the single-source vision that was once touted as the real benefit of Enterprise Data Warehouses.
  I’ve always thought of self-service as something of a cop-out. It tends to avoid data teams doing anything as arduous (and in some cases out of their comfort zone) as understanding what makes a business tick and getting to grips with the key questions that an organisation needs to answer in order to be successful [3]. With this messy and human-centric stuff out of the way, the data team can retreat into the comfort of nice orderly technological matters or friendly statistical models.

However, what Eckerson Group describe here is “an Amazon-like data marketplace”, which it seems to me has more of a chance of being successful. However, such a marketplace will only function if it embodies the same focus on key business questions and how they are answered. The paradigm within which such questions are framed may be different, more community based and more federated for example, but the questions will still be of paramount importance.

 
3.
 
New kinds of data governance organizations and practices emerge. Long-standing, command-and-control data governance practices fail to meet the challenges of big data and of data democratization. […]
  I think that this is overdue. To date Data Governance, where it is implemented at all, tends to be too police-like. I entirely agree that there are circumstances in which a Data Governance team or body needs to be able to put its foot down [4], but if all that Data Governance does is police-work, then it will ultimately fail. Instead good Data Governance needs to recognise that it is part of a much more fluid set of processes [5], whose aim is to add business value; to facilitate things being done as well as sometimes to stop the wrong path being taken.

 
Data Science

Data Science

1. Self-service and automated predictive analytics tools will cause some embarrassing mistakes. Business users now have the opportunity to use predictive models but they may not recognize the limits of the models themselves. […]
  I think this is a very valid point. As well as not understanding the limitations of some models [6], there is not widespread understanding of statistics in many areas of business. The concept of a central prediction surrounded by different outcomes with different probabilities is seldom seen in commercial circles [7]. In addition there seems to be a lack of appreciation of how big an impact the statistical methodology employed can have on what a model tells you [8].

 
Business Analytics

Business Analytics

1. Modern analytic platforms dominate BI. Business intelligence (BI) has evolved from purpose-built tools in the 1990s to BI suites in the 2000s to self-service visualization tools in the 2010s. Going forward, organizations will replace tools and suites with modern analytics platforms that support all modes of BI and all types of users […]
  Again, if it comes to fruition, such consolidation is overdue. Ideally the tools and technologies will blend into the background, good data-centric work is never about the technology and always about the content and the efforts involved in ensuring that it is relevant, accurate, consistent and timely [9]. Also information is often of most use when it is made available to people taking decisions at the precise point that they need it. This observation highlights the need for data to be integrated into systems and digital estates instead of simply being bound to an analytical hub.

 
So some food for thought from Wayne and his associates. The points they make (including those which I haven’t featured in this article) are serious and well-thought-out ones. It will be interesting to see how things have moved on by the beginning of 2018.

According to WikiQuotes, this has most famously been attributed to Danish theoretical physicist and father of Quantum Mechanics, Niels Bohr (in Teaching and Learning Elementary Social Studies (1970) by Arthur K.

Perhaps it is best to say that a Dane made the comment and leave it at that.

Alphabet Soup

Alphabet soup

This article is about the latest consumer product from the Google stable, something which will revolutionise your eating experience by combining a chicken-broth base with a nanotechnology garnish and a soupçon of deep learning techniques to create a warming meal that also provides a gastro-intestinal health-check. Wait…

…I may have got my wires crossed a bit there. No, I mis-spoke, the article is actually about ever increasing number of CxO titles [1], which has made a roster of many organisations’ executives come to resemble a set of Scrabble tiles.

Specifically I will focus on two values of x, A and D, so the CAO and CDO roles [2]. What do these TLAs [3] stand for, what do people holding these positions do and can we actually prove that, for these purposes only, “A” ≡ “D”?
 
 
Breaking the Code

CDO & CAO

The starting position is not auspicious. What might CAO stand for? Existing roles that come to mind include: Chief Accounting Officer and Chief Administrative Officer. However, in our context, it actually stands for Chief Analytics Officer. There is no ISO definition of Analytics, as I note in one of my recent seminar decks [4] (quoting the Gartner IT Glossary, but with my underlining):

Analytics has emerged as a catch-all term for a variety of different business intelligence and application-related initiatives. In particular, BI vendors use the ‘analytics’ moniker to differentiate their products from the competition. Increasingly, ‘analytics’ is used to describe statistical and mathematical data analysis that clusters, segments, scores and predicts what scenarios are most likely to happen.

I should of course mention here that my current role incorporates the word “Analytics” [5], so I may be making a point against myself. But before I start channeling my 2009 article, Business Analytics vs Business Intelligence [6], I’ll perhaps instead move on to the second acronym. How to decode CDO? Well an equally recent translation would be Chief Digital Officer, but you also come across Chief Development Officer and sometimes even Chief Diversity Officer. Our meaning will however be Chief Data Officer. You can read about what I think a CDO does here.

A observation that is perhaps obvious to make at this juncture is that when the acronym of a role is not easy to pin down, the content of the role may be equally amorphous. It is probably fair to say that this is true of both CAO and CDO job descriptions. Both are emerging roles in the majority of organisations.
 
 
Before the Flood

HMS/USS* Chief Information Officer (* delete as applicable)

One thing that both roles have in common is that – in antediluvian days – their work used to be the province of another CxO, the CIO. This was before many CIOs became people who focus on solution architecture, manage relationships with outsourcers and have their time consumed by running Service Desks and heading off infrastructure issues [7]. Where organisations may have had just a CIO, they may well now have a CIO, a CAO and a CDO (and also a CTO perhaps which splits one original “C” role into four).

Aside from being a job creation scheme, the reasons for such splits are well-documented. The prevalence of outsourcing (and the complexity of managing such arrangements); the pervasiveness and criticality of technology leading to many CIOs focussing more on the care and feeding of systems than how businesses employ them; the relentless rise of Change organisations; and (frequently related to the last point) the increase in size of IT departments (particularly if staff in external partner organisations are included). All of these have pushed CIOs into more business as usual / back-room / engineering roles, leaving a vacuum in the nexus between business, technology and transformation. The fact that data processing is very different to data collation and synthesis has been another factor in CAOs and / or CDOs filling this vacuum.
 
 
Some other Points of View

James Taylor Robert Morison Jen Stirrup

As trailed in some previous articles [8], I have been thinking about the potential CAO / CDO dichotomy for some time. Towards the beginning of this period I read some notes that decision management luminary James Taylor had published based on the proceedings of the 2015 Chief Analytics Officer Summit. In the first part of these he cites comments made by Robert Morison as follows:

Practically speaking organizations need both roles [CAO and CDO] filled – either by one person or by two working closely together. This is hard because the roles are both new and evolving – role clarity was not the norm creating risk. In particular if both roles exist they must have some distinction such as demand v supply, offense v defense – adding value to data with analytics v managing data quality and consistency. But enterprises need to be ready – in particular when data is being identified as an asset by the CEO and executive team. CDOs tend to be driven by fragmented data environments, regulatory challenges, customer centricity. CAO tends to be driven by a focus on improving decision-making, moving to predictive analytics, focusing existing efforts.

Where CAO and CDO roles are separate, the former tends to work on exploiting data, the latter on data foundations / compliance. These are precisely the two vertical extremities of the spectrum I highlighted in The Chief Data Officer “Sweet Spot”. As Robert points out, in order for both to be successful, the CAO and CDO need to collaborate very closely.

Around the same time, another take on the same general question was offered by Jen Stirrup in her 2015 PASS Diary [9] article, Why are PASS doing Business Analytics at all?. Here Jen cites the Gartner distinctions between descriptive, diagnostic, predictive and prescriptive analytics adding that:

Business Intelligence and Business Analytics are a continuum. Analytics is focused more on a forward motion of the data, and a focus on value.

Channeling Douglas Adams, this model can be rehashed as:

  1. What happened?
  2. Why did it happen?
  3. What is going to happen next?
  4. What should we be doing?

As well as providing a finer grain distinguishing different types of analytics, the steps necessary to answer these questions also tend to form a bridge between what might be regarded as definitively CDO work and what might be regarded as definitively CAO work. As Jen notes, it’s a continuum. Answering “What happened?” with any accuracy requires solid data foundations and decent data quality, working out “What is going to happen next?” requires each of solid data foundations, decent data quality and a statistical approach.
 
 
Much CDO about Nothing

Just an excuse to revist a happy ending for Wesley Wyndam-Pryce and Winifred Burkle - I'm such a fanboy :-o

In some organisations, particularly the type where headcount is not a major factor in determining overall results, separate CAO and CDO departments can coexist; assuming of course that their leaders recognise their mutual dependency, park their egos at the door and get on with working together. However, even in such organisations, the question arises of to whom should the CAO and CDO report, a single person, two different people, or should one of them report to the other? In more cost-conscious organisations entirely separate departments may feel like something of a luxury.

My observation is that CAO staff generally end up doing data collation and cleansing, while CDO staff often get asked to provide data and carry out data analysis. This blurs what is already a fairly specious distinction between the two areas and provides scope for both duplication of work and – more worryingly – different answers to the same business questions. As I have mentioned in earlier articles, to anyone engaged in the fields, Analytics and Data Management are two sides of the same coin and both benefit from being part of the same unitary management structure.

Alignment of Data teams

If we consider the arrangements on the left-hand side of the above diagram, the two departments may end up collaborating, but the structure does not naturally lead to this. Indeed, where the priorities of the people that the CAO and CDO report in to differ, then there is scope for separate agendas, unhealthy competition and – again – duplication and waste. It is my assertion that the arrangements on the right-hand side are more likely to lead to a cohesive treatment of the spectrum of data matters and thus superior business outcomes.

In the right-hand exhibit, I have intentionally steered away from CAO and CDO titles. I recognise that there are different disciplines within the data world, but would expect virtual teams to form, disband and reform as required drawing on a variety of skills and experience. I have also indicated that the whole area should report into a single person, here given the monicker of TDJ (or Top Data Job [10]). You could of course map Analytics Lead to CAO and Data Management lead to CDO if you chose. Equally you could map one or other of these to the TDJ, with the other subservient. To an extent it doesn’t really matter. What I do think matters is that the TDJ goes to someone who understands the whole data arena; both the CAO and CDO perspectives. In my opinion this rules out most CEOs, COOs and CFOs from this role.
 
 
More or less Mandatory Sporting Analogy [11]

Association Football Free Kick

An analogy here comes from Robert Morison’s mention of “offense v defense” [12]. This puts me in mind of an [Association] Football Manager. In Soccer (to avoid further confusion), there are not separate offensive and defensive teams, whose presence on the field of play are mutually exclusive. Instead your defenders and attackers are different roles within one team; also sometimes defenders have to attack and attackers have to defend. The arrangements in the left-hand organogram are as if the defenders in a Soccer team were managed by one person, the attackers by another and yet they were all expected to play well together. Of course there are specialist coaches, but there is one Manager of a Soccer team who has overall accountability for tactics, selection and style of play (they also manage any specialist coaches). It is generally the Manager who lives or dies according to their team’s success. Equally, in the original right-hand organogram, if the TDJ is held by someone who understands just analytics or just data management, then it is like a Soccer Manager who only understands attack, but not defence.

The point I am trying to make is probably more readily apprehended via the following diagram:

Football-teams

On the assumption that the Manager on the right knows a lot about both attack and defence in Soccer, whereas the team owner is at best an interested amateur, then is the set up on the left or on the right likely to be a more formidable footballing force?

Even in American Football the analogy still holds. There are certainly offensive and defensive coaches, each of whom has “their” team on the park for a period. However, it is the Head Coach who calls the shots and this person needs to understand all of the nuances of the game.
 
 
In Closing

So, my recommendation is that – in data matters – you similarly have someone in the Top Data Job, with a broad knowledge of all aspects of data. They can be supported by specialists of course, but again someone needs to be accountable. To my mind, we already have a designation for such as person, a Chief Data Officer. However, to an extent this is semantics. A Chief Analytics Officer who is knowledgeable about Data Governance and Data Management could be the head data honcho [13], but one who only knows about analytics is likely to have their work cut out for them. Equally if CAO and CDO functions are wholly separate and only come together in an organisation under someone who has no background in data matters, then nothing but problems is going to arise.

The Top Data Job – or CDO in my parlance – has to be au fait with the span of data activities in an organisation and accountable for all work pertaining to data. If not then they will be as useful as a Soccer Manager who only knows about one aspect of the game and can only direct a handful of the 11 players on the field. Do organisations want some chance of winning the game, or to tie their hands behind their backs and don a blindfold before engaging in data activities? The choice should not really be a difficult one.

The Chief Data Officer “Sweet Spot”

CDO "sweet spot"

I verbally “scribbled” something quite like the exhibit above recently in conversation with a longstanding professional associate. This was while we were discussing where the CDO role currently sat in some organisations and his or her span of responsibilities. We agreed that – at least in some cases – the role was defined sub-optimally with reference to the axes in my virtual diagram.

This discussion reminded me that I was overdue a piece commenting on November’s IRM(UK) CDO Executive Forum; the third in a sequence that I have covered in these pages [1], [2]. In previous CDO Exec Forum articles, I have focussed mainly on the content of the day’s discussions. Here I’m going to be more general and bring in themes from the parent event; IRM(UK) Enterprise Data / Business Intelligence 2016. However I will later return to a theme central to the Exec Forum itself; the one that is captured in the graphic at the head of this article.

As well as attending the CDO Forum, I was speaking at the umbrella event. The title of my talk was Data Management, Analytics, People: An Eternal Golden Braid [3].

Data Management, Analytics, People: An Eternal Golden Braid

The real book, whose title I had plagiarised, is Gödel, Escher and Bach, an Eternal Golden braid, by Pulitzer-winning American Author and doyen of 1970s pop-science books, Douglas R. Hofstadter [4]. This book, which I read in my youth, explores concepts in consciousness, both organic and machine-based, and their relation to recursion and self-reference. The author argued that these themes were major elements of the work of each of Austrian Mathematician Kurt Gödel (best known for his two incompleteness theorems), Dutch graphic artist Maurits Cornelis Escher (whose almost plausible, but nevertheless impossible buildings and constantly metamorphosing shapes adorn both art galleries and college dorms alike) and German composer Johann Sebastian Bach (revered for both the beauty and mathematical elegance of his pieces, particularly those for keyboard instruments). In an age where Machine Learning and other Artificial Intelligence techniques are moving into the mainstream – or at least on to our Smartphones – I’d recommend this book to anyone who has not had the pleasure of reading it.

In my talk, I didn’t get into anything as metaphysical as Hofstadter’s essays that intertwine patterns in Mathematics, Art and Music, but maybe some of the spirit of his book rubbed off on my much lesser musings. In any case, I felt that my session was well-received and one particular piece of post-presentation validation had me feeling rather like these guys for the rest of the day:

The cast and author / director of Serenity at Comic Con

What happened was that a longstanding internet contact [5] sought me out and commended me on both my talk and the prescience of my July 2009 article, Is the time ripe for appointing a Chief Business Intelligence Officer? He argued convincingly that this foreshadowed the emergence of the Chief Data Officer. While it is an inconvenient truth that Visa International had a CDO eight years earlier than my article appeared, on re-reading it, I was forced to acknowledge that there was some truth in his assertion.

To return to the matter in hand, one point that I made during my talk was that Analytics and Data Management are two sides of the same coin and that both benefit from being part of the same unitary management structure. By this I mean each area reporting into an Executive who has a strong grasp of what they do, rather than to a general manager. More specifically, I would see Data Compliance work and Data Synthesis work each being the responsibility of a CDO who has experience in both areas.

It may seem that crafting and implementing data policies is a million miles from data visualisation and machine learning, but to anyone with a background in the field, they are much more strongly related. Indeed, if managed well (which is often the main issue), they should be mutually reinforcing. Thus an insightful model can support business decision-making, but its authors would generally be well-advised to point out any areas in which their work could be improved by better data quality. Efforts to achieve the latter then both improve the usefulness of the model and help make the case for further work on data remediation; a virtuous circle.

CDO "sweet spot" vertical axis

Here we get back to the vertical axis in my initial diagram. In many organisations, the CDO can find him or herself at the extremities. Particularly in Financial Services, an industry which has been exposed to more new regulation than many in recent years, it is not unusual for CDOs to have a Risk or Compliance background. While this is very helpful in areas such as Governance, it is less of an asset when looking to leverage data to drive commercial advantage.

Symmetrically, if a rookie CDO was a Data Scientist who then progressed to running teams of Data Scientists, they will have a wealth of detailed knowledge to fall back on when looking to guide business decisions, but less familiarity with the – sometimes apparently thankless, and generally very arduous – task of sorting out problems in data landscapes.

Despite this, it is not uncommon to see CDOs who have a background in just one of these two complementary areas. If this is the case, then the analytics expert will have to learn bureaucratic and programme skills as quickly as they can and the governance guru will need to expand their horizons to understand the basics of statistical modelling and the presentation of information in easily digestible formats. It is probably fair to say that the journey to the centre is somewhat perilous when either extremity is the starting point.

CDO "sweet spot" vertical axis

Let’s now think about the second and horizontal axis. In some organisations, a newly appointed CDO will be freshly emerged from the ranks of IT (in some they may still report to the CIO, though this is becoming more of an anomaly with each passing year). As someone whose heritage is in IT (though also from very early on with a commercial dimension) I understand that there are benefits to such a career path, not least an in-depth understanding of at least some of the technologies employed, or that need to be employed. However a technology master who is also a business neophyte is unlikely to set the world alight as a newly-minted CDO. Such people will need to acquire new skills, but the learning curve is steep.

To consider the other extreme of this axis, it is undeniable that a CDO organisation will need to undertake both technical and technological work (or at least to guide this in other departments). Therefore, while an in-depth understanding of a business, its products, markets, customers and competitors will be of great advantage to a new CDO, without at least a reasonable degree of technical knowledge, they may struggle to connect with some members of their team; they may not be able to immediately grasp what technology tasks are essential and which are not; and they may not be able to paint an accurate picture of what good looks like in the data arena. Once more rapid assimilation of new information and equally rapid acquisition of new skills will be called for.

At this point it will be pretty obvious that my central point here is that the “sweet spot” for a CDO, the place where they can have greatest impact on an organisation and deliver the greatest value, is at the centre point of both of these axes. When I was talking to my friend about this, we agreed that one of the reasons why not many CDOs sit precisely at this nexus is because there are few people with equal (or at least balanced) expertise in the business and technology fields; few people who understand both data synthesis and data compliance equally well; and vanishingly few who sit in the centre of both of these ranges.

Perhaps these facts would also have been apparent from revewing the CDO job description I posted back in November 2015 as part of Wanted – Chief Data Officer. However, as always, a picture paints a thousand words and I rather like the compass-like exhibit I have come up with. Hopefully it conveys a similar message more rapidly and more viscerally.

To bring things back to the IRM(UK) CDO Executive Forum, I felt that issues around where delegates sat on my CDO “sweet spot” diagram (or more pertinently where they felt that they should sit) were a sub-text to many of our discussions. It is worth recalling that the mainstream CDO is still an emergent role and a degree of confusion around what they do, how they do it and where they sit in organisations is inevitable. All CxO roles (with the possible exception of the CEO) have gone through similar journeys. It is probably instructive to contrast the duties of a Chief Risk Officer before 2008 with the nature and scope of their responsibilities now. It is my opinion that the CDO role (and individual CDOs) will travel an analogous path and eventually also settle down to a generally accepted set of accountabilities.

In the meantime, if your organisation is lucky enough to have hired one of the small band of people whose experience and expertise already place them in the CDO “sweet spot”, then you are indeed fortunate. If not, then not all is lost, but be prepared for your new CDO to do a lot of learning on the job before they too can join the rather exclusive club of fully rounded CDOs.
 


 
Epilogue

As an erstwhile Mathematician, I’ve never seen a framework that I didn’t want to generalise. It occurs to me and – I assume – will also occur to many readers that the North / South and East / West diagram I have created could be made even more compass-like by the addition of North East / South West and North West / South East axes, with our idealised CDO sitting in the middle of these spectra as well [6].

Readers can debate amongst themselves what the extremities of these other dimensions might be. I’ll suggest just a couple: “Change” and “Business as Usual”. Given how organisations seem to have evolved in recent years, it is often unfortunately a case of never the twain shall meet with these two areas. However a good CDO will need to be adept at both and, from personal experience, I would argue that mastery of one does not exclude mastery of the other.

5 More Themes from a Chief Data Officer Forum

A rather famous theme

This article is the second of two pieces reflecting on the emerging role of the Chief Data Officer. Each article covers 5 themes. You can read the first five themes here.

As with the first article, I would like to thank both Peter Aiken, who reviewed a first draft of this piece and provided useful clarifications and additional insights, and several of my fellow delegates, who also made helpful suggestions around the text. Again any errors of course remain my responsibility.
 
 
Introduction Redux

After reviewing a draft of the first article in this series and also scanning an outline of this piece, one of the other attendees at the inaugural IRM(UK) / DAMA CDO Executive Forum rightly highlighted that I had not really emphasised the strategic aspects of the CDO’s work; both data / information strategy and the close linkage to business strategy. I think the reason for this is that I spend so much of my time on strategic work that I’ve internalised the area. However, I’ve come to the not unreasonable conclusion that internalisation doesn’t work so well on a blog, so I will call out this area up-front (as well as touching on it again in Theme 10 below).

For more of my views on strategy formation in the data / information space please see my trilogy of articles starting with: Forming an Information Strategy: Part I – General Strategy.

With that said, I’ll pick up where we left off with the themes that arose in the meeting: 
 
Theme 6 – While some CDO roles have their genesis in risk mitigation, most are focussed on growth

Epidermal growth factor receptor

This theme gets to the CDO / CAO debate (which I will be writing about soon). It is true that the often poor state of data governance in organisations is one reason why the CDO role has emerged and also that a lot of CDO focus is inevitably on this area. The regulatory hurdles faced by many industries (e.g. Solvency II in my current area of Insurance) also bring a significant focus on compliance to the CDO role. However, in the unanimous view of the delegates, while cleaning the Augean Stables is important and equally organisations which fail to comply with regulatory requirements tend to have poor prospects, most CDOs have a growth-focussed agenda. Their primary objective is to leverage data (or to facilitate its leverage) to drive growth and open up new opportunities. Of course good data management is a prerequisite for achieving this objective in a sustainable manner, but it is not an end in itself. Any CDO who allows themself to be overwhelmed by what should just be part of their role is probably heading in the same direction as a non-compliant company.
 
 
Theme 7 – New paradigms are data / analytics-centric not application-centric

Applications & Data

Historically, technology landscapes used to be application-centric. Often there would be a cluster of systems in the centre (ideally integrated with each other in some way) and each with their own analytics capabilities; a CRM system with customer analytics “out-of-the-box” (whatever that really means in practice), an ERP system with finance analytics and maybe supply-chain analytics, digital estates with web analytics and so on. Even if there was a single-central system (those of us old enough will still remember the ERP vision), then this would tend to have various analytical repositories around it used by different parts of the organisation for different purposes. Equally some of the enterprise data warehouses I have built have included specialist analytical repositories, e.g. to support pricing, or risk, or other areas.

Today a new paradigm is emerging. Under this, rather than being at the periphery, data and analytics are in the centre, operating in a more joined-up manner. Many companies have already banked the automation and standardisation benefits of technology and are now looking instead to exploit the (often considerably larger) information and insight benefits [1]. This places information and insight assets at the centre of the landscape. It also means that finally information needs can start to drive system design and selection, not the other way round.
 
 
Theme 8 – Data and Information need to be managed together

Data and Information in harness

We see a further parallel with the CAO vs CDO debate here [2]. After 27 years with at least one foot in IT (though often in hybrid roles with dual business / IT reporting) and 15 explicitly in the data and information space, I really fail to see how data and information are anything other than two sides of the same coin.

To people who say that the CAO is the one who really understands the business and the CDO worries instead about back-end data governance, I would reply that an engine is only as good as the fuel that you put into it. I’d over-extend the analogy (as is my wont [3]) by saying that the best engineers will have a thorough understanding of:

  1. what purpose the engine will be applied to – racing car, or lorry (truck)
  2. the parameters within which it is required to perform
  3. the actual performance requirements
  4. what that means in terms of designing the engine
  5. what inputs the engine will have: petrol/diesel/bio-fuel/electricity
  6. what outputs it will produce (with no reference to poor old Volkswagen intended)

It may be that the engineering team has experts in various areas from metallurgy, to electronics, to chemistry, to machining, to quality control, to noise and vibration suppression, to safety, to general materials science and that these are required to work together. But whoever is in charge of overall design, and indeed overall production, would need to have knowledge spanning all these areas and would in addition need to ensure that specialists under their supervision worked harmoniously together to get the best result.

Data is the basic building block of information. Information is the embodiment of things that people want or need to know. You cannot generate information (let alone insight) without a very strong understanding of data. You can neither govern, nor exploit, data in any useful way without knowledge of the uses to which it will be put. Like the chief product engineer, there is a need for someone who understands all of the elements, all of the experts working on these and can bring them together just as harmoniously [4]).
 
 
Theme 9 – Data Science is not enough

If you don't understand  the notation, you've failed in your application to be a  Data Scientist

In Part One of this article I repeated an assertion about the typical productivity of data scientists:

“Data Scientists are only 10-20% productive; if you start a week-long piece of work on Monday, the actual statistical analysis will commence on Friday afternoon; the rest of the time is battling with the data”

While the many data scientists I know would attest to the truth of this, there is a broader point to be made. That is the need for what can be described as Data Interpreters. This role is complementary to the data science community, acting as an interface between those with PhDs in statistics and the rest of the world. At IRM(UK) ED&BI one speaker even went so far as to present a photo graph of two ladies who filled these ying and yang roles at a European organisation.

More broadly, the advent of data science, while welcome, has not obviated the need to pass from data through information to get to insight for most of an organisation’s normal measurements. Of course an ability to go straight from data to insight is also a valuable tool, but it is not suitable for all situations. There are also a number of things to be aware of before uncritically placing full reliance on statistical models [5].
 
 
Theme 10 – Information is often a missing link between Business and IT strategies

Business => Information => IT

This was one of the most interesting topics of discussion at the forum and we devoted substantial time to exploring issues and opportunities in this area. The general sense was that – as all agreed – IT strategy needs to be aligned with business strategy [6]. However, there was also agreement that this can be hard and in many ways is getting harder. With IT leaders nowadays often consumed by the need to stay abreast of both technology opportunities (e.g. cloud computing) and technology threats (e.g. cyber crime) as well as inevitably having both extensive business as usual responsibilities and significant technology transformation programmes to run, it could be argued that some IT departments are drifting away from their business partners; not through any desire to do so, but just because of the nature (and volume) of current work. Equally with the increasing pace of business change, few non-IT executives can spend as much time understanding the role of technology as was once perhaps the case.

Given that successful information work must have a foot in both the business and technology camps (“what do we want to do with our data?” and “what data do we have available to work with?” being just two pertinent questions), the argument here was that an information strategy can help to build a bridge these two increasingly different worlds. Of course this chimes with the feedback on the primacy of strategy that I got on my earlier article from another delegate; and which I reference at the beginning of this piece. It also is consistent with my own view that the data → information → insight → action journey is becoming an increasingly business-focused one.

A couple of CDO Forum delegates had already been thinking about this area and went so far as to present models pertaining to a potential linkage, which they had either created or adapted from academic journals. These placed information between business and IT pillars not just with respect to strategy but also architecture and implementation. This is a very interesting area and one which I hope to return to in coming weeks.
 
 
Concluding thoughts

As I mentioned in Part One, the CDO Forum was an extremely useful and thought-provoking event. One thing which was of note is that – despite the delegates coming from many different backgrounds, something which one might assume would be a barrier to effective communication – they shared a common language, many values and comparable views on how to take the areas of data management and data exploitation forward. While of course delegates at an such an eponymous Forum might be expected to emphasise the importance of their position, it was illuminating to learn just how seriously a variety organisations were taking the CDO role and that CDOs were increasingly becoming agents of growth rather than just risk and compliance tsars.

Amongst the many other themes captured in this piece and its predecessor, perhaps a stand-out was how many organisations view the CDO as a firmly commercial / strategic role. This can only be a positive development and my hope is that CDOs can begin to help organisations to better understand the asset that their data represents and then start the process of leveraging this to unlock its substantial, but often latent, business value.

5 Themes from a Chief Data Officer Forum

A rather famous theme

This article is the first of two pieces reflecting on the emerging role of the Chief Data Officer. Each article will cover 5 themes and the concluding chapter may be viewed here.

I would like to thank both Peter Aiken, who reviewed a first draft of this piece and provided useful clarifications and additional insights, and several of my fellow delegates, who also made helpful suggestions around the text. Any errors of course remain my responsibility.
 
 
Introduction

As previously trailed, I attended the IRM(UK) Enterprise Data & Business Intelligence seminar on 3rd and 4th November. On the first of these days I sat on a panel talking about approaches to leveraging data “beyond the Big Data hype”. This involved fielding some interesting questions, both from the Moderator – Mike Simons – and the audience; I’ll look to pen something around a few of these in coming days. It was also salutary that each one of the panellists cast themselves as sceptics with respect to Big Data (the word “Luddite” was first discussed as an appropriate description, only to then be discarded); feeling that it was a very promising technology but a long way from the universal panacea it is often touted to be.

However it is on the second day of the event that I wanted to focus in this article. During this I was asked to attend the inaugural Chief Data Officer Executive Forum, sponsored by long-term IRM partner DAMA, the international data management association. This day-long event was chaired by data management luminary Peter Aiken, Associate Professor of Information Systems at Virginia Commonwealth University and Founding Director of data management consultancy Data Blueprint.

The forum consisted of a small group of people working in the strongly-related arenas of data management, data governance, analytics, warehousing and information architecture. Some attendees formally held the title of CDO, some carried out functions overlapping or analogous to the CDO. This is probably not surprising given the emergent nature of the CDO role in many industries.

There was a fair mix of delegate backgrounds, including people who previously held commercial roles, or ones in each of finance, risk and technology (a spread that I referred to in my pre-conference article). The sectors attendees worked in ranged from banking, to manufacturing, to extractives, to government to insurance. A handful of DAMA officers made up the final bakers’ dozen of “wise men” [1].

Discussions were both wide-ranging and very open, so I am not going to go into specifics of what people said, or indeed catalogue the delegates or their organisations. However, I did want to touch on some of the themes which arose from our interchanges and I will leaven these with points made in Peter Aiken’s excellent keynote address, which started the day in the best possible way.
 
 
Theme 1 – Chief Data Officer is a full-time job

Not a part-time activity

In my experience in business, things happen when an Executive is accountable for them and things languish when either a committee looks at an area (= no accountability), or the work receives only middle-management attention (= no authority). If both being a guardian of an organisation’s data (governance) and caring about how this is leveraged to deliver value (exploitation) are important things, then they merit Executive ownership.

Equally it can be tempting to throw the data and information agenda to an existing Executive, maybe one who already plays in the information arena such as the CFO. The problem with this is that I don’t know many CFOs who have a lot of spare time. They tend to have many priorities already. Let’s say that your average CFO has 20 main things that they worry about. When they add data and information to this mix, then let’s be optimistic and say this slots in at number 15. Is this really going to lead to paradigm-shifting work on data exploitation or data governance?

For most organisations the combination of Data Governance and Data Exploitation is a huge responsibility in terms of both scope and complexity. It is not work to be approached lightly and definitively not territory where a part-timer will thrive.

Peter Aiken also emphasizes that a newly appointed CDO may well find him or herself looking to remediate years of neglect for areas such as data management. The need to address such issues suggests that focus is required.

To turn things round, how many organisations of at least a reasonable size have one of their executives act as CFO on a part time basis?
 
 
Theme 2 – The CDO most logically reports into a commercial area (CEO or COO)

Where does the CDO fit?

I’d echo Peter Aiken’s comments that IT departments and the CIOs who lead them have achieved great things in the past decades (I’ve often been part of the teams doing just this). However today (often as a result of just such successes) the CIO’s remit is vast. Even just care and feeding of the average organisation’s IT estate is a massive responsibility. If you add in typical transformation programmes as well, it is easy to see why most CIOs are extremely busy.

Another interesting observation is that the IT project mindset – while wholly suitable for the development, purchase and integration of transaction processing systems – is less aligned with data-centric work. This is because data evolves. Peter Aiken also talks about data operating at a different cadence, by which he means the flow or rhythm of events, especially the pattern in which something is experienced.

More prosaically, anyone who has seen the impact of a set of parallel and uncoordinated projects on a previously well-designed data warehouse will be able to attest to the project and asset mindsets not mingling too well in the information arena. Also, unlike much IT work, data-centric activities are not always ones that can be characterised by having a beginning, middle and end; then tend to be somewhat more open ended as an organisation’s data seldom is static and its information needs have similar dynamism.

Instead, the exploitation of an organisation’s data is essentially a commercial exercise which is 100% targeted at better business decision making. This work should be focussed on adding value (see also Theme 5 below). Both of these facts argue for the responsible function reporting outside of IT (but obviously with a very strong technical flavour). Logical reporting lines are thus into either the CEO or COO, assuming that the latter is charged with the day-to-day operations of the business [2].
 
 
Theme 3 – The span of CDO responsibilities is still evolving

Answers on a postcard...

While there are examples of CDOs being appointed in the early 2000s, the role has really only recently impinged on the collective corporate consciousness. To an extent, many organisations have struggled with the data → information → insight → action journey, so it is unsurprising that the precise role of the CDO is at present not entirely clear. Is CDO a governance-focussed role, or an information-generating role, or both? How does a CDO relate to a Chief Analytics Officer, or are they the same thing? [3]

It is evident that there is some confusion here. On the assumption (see Theme 2 above) that the CDO sits outside IT, then how does it relate to IT and where should data-centric development resource be deployed? How does the CDO relate to compliance and risk? [4]

The other way of looking at this is that there is a massive opportunity for embryonic CDOs to define their function and span of control. We have had CFOs and their equivalents for centuries (longer if you go back to early Babylonian Accounting), how exciting would it be to frame the role and responsibilities of an entirely new C-level executive?
 
 
Theme 4 – Data Management is an indispensable foundation for Analytics, Visualisation and Statistical Modelling

Look out for vases containing scorpions...

Having been somewhat discursive on the previous themes, here I will be brief. I’ve previously argued that a picture paints a thousand words [5] and here I’ll simply include my poor attempt at replicating an exhibit that I have borrowed from Peter Aiken’s deck. I think it speaks for itself:

Data Governance Triangle

You can view Peter’s original, which I now realise diverges rather a lot from my attempt to reproduce it, here.

I’ll close this section by quoting a statistic from the plenary sessions of the seminar: “Data Scientists are only 10-20% productive; if you start a week-long piece of work on Monday, the actual statistical analysis will commence on Friday afternoon; the rest of the time is battling with the data” [6].

CDOs should be focussed on increasing the productivity of all staff (Data Scientists included) by attending to necessary foundational work in the various areas highlighted in the exhibit above.
 
 
Theme 5 – The CDO is in the business of driving cultural change, not delivering shiny toys

When there's something weird on your board of dash / When there's something weird and it's kinda crass / Who you gonna call?

While all delegates agreed that a CDO needs to deliver business value, a distinction was made between style and substance. As an example, Big Data is a technology – an exciting one which allows us to do things we have not done before, but still a technology. It needs to be supported and rounded out by attention to process and people. The CDO should be concerned about all three of these dimensions (see also Theme 4 above).

I mentioned at the beginning of this article that some of the attendees at the CDO forum hailed from the extractive industries. We had some excellent discussions about how safety has been embedded in the culture of such organisations. But we also spoke about just how long this has taken and how much effort was required to bring about the shift in mindset. As always, changing human behaviour is not a simple or quick thing. If one goal of a CDO is to embed reliance on credible information (including robust statistical models) into an organisation’s DNA, then early progress is not to be anticipated; instead the CDO should be dug in for the long-term and have vast reserves of perseverance.

As regular readers will be unsurprised to learn, I’m delighted with this perspective. Indeed tranches of this blog are devoted precisely to the important area [7]. I am also somewhat allergic to a focus on fripperies at the expense of substance, something I discussed most directly in “All that glisters is not gold” – some thoughts on dashboards. These perspectives seem to be well-aligned with the stances being adopted by many CDOs.

As with any form of change, the group unanimously felt that good communication lay at the heart of success. A good CDO needs to be a consummate communicator.
 
 
Tune in next time…

I have hopefully already given some sense of the span of topics the CDO Executive Forum discussed. The final article in this short series covers a further 5 themes and then look to link these together with some more general conclusions about what a CDO should do and how they should do it.

Somewhat encouragingly three of these were actually wise women, then maybe I am setting the bar too low!

Though if reporting to a COO, the CDO will need to make sure that they stay close to wherever business strategy is developed; perhaps the CEO, perhaps a senior strategy or marketing executive.
