Data aggregation and reporting principles – applied common sense

Principles for effective risk data aggregation and risk reporting

Basel Consultative Document
Data aggregation and reporting principles (BCBS 239)

Those of you familiar with my blog will know that I am a fan of common sense.

I believe that data quality management requires one to apply common sense principles and processes to your data.  I believe that the same common sense principles apply regardless of the industry you are in.

Your data will be unique, but the common sense questions you must ask yourself will be the same.  They include:

  • What MI reports do we need to run our business?
  • What critical data do we need in our MI reports?
  • Who owns and is responsible for gathering the critical data we need in our MI reports?
  • What should our critical data contain?
  • What metrics do we have to verify our critical data contains what it should?
  • etc…

Click on the image to see a document that lists what I regard as “common sense” data aggregation and reporting principles.  They were published as a consultative document on 26th June 2012 by the Basel committee on Banking Supervision (BCBS). The principles are commonly known as BCBS 239. The committee invited comments from interested parties, which are available at I co-operated with a group of fellow independent data professionals to comment and you may see our comments at You may see the final version at The largest banks in the world (known as Global Systemically Important Banks, or G-SIBS) must comply by Jan 2016. Other, “Domestic Systemically important banks”, or D-SIBS, must reach compliance three years after the date on which they were so designated, which varies by bank. Many received their designation during 2014.

While the document is targeted at risk management within the banking industry, the principles apply to all industries. The document explicitly refers to “Risk data aggregation and risk reporting” – I suggest you ignore the word risk and read it as “data aggregation and reporting principles”.

Over the next while I plan to explore some the principles proposed in the document. I plan to explore the practical challenges that arise when one seeks to implement common sense data quality management principles. I welcome your input.  If you have a specific question – let me know – I will do my best to answer it.

Risk data aggregation and risk reporting – Board and senior management responsibilities

Do you know what’s in the data you’re consuming?

Standard facts are provided about the food we buy

These days, food packaging includes ingredients and a standard set of nutrition facts.  This is required by law in many countries.

Food consumers have grown accustomed to seeing this information, and now expect it. It enables them to make informed decisions about the food they buy, based on a standard set of facts.

Remarkable as it may seem, data consumers are seldom provided with facts about the data feeding their critical business processes.

Most data consumers assume the data input to their business processes is “right”, or “OK”.  They often assume it is the job of the IT function to ensure the data is “right”.  But only the data consumer knows the intended purpose for which they require the data.  Only the data consumer can decide whether the data available satisfies their specific needs and their specific acceptance criteria. To make an informed choice, data consumers need to be provided with facts about the data content available.

Data Consumers have the right to make informed decisions based on standard data content facts

The IT function, or a data quality function, can, and should provide standard “data content facts” about all critical data such as the facts shown in the example.

In the sample shown, a Marketing Manager wishing to mailshot customers in the 40-59 age range might find that the data content facts satisfy his/her data quality acceptance criteria.

The same data might not satisfy the acceptance criteria for a manager in the Anti Money Laundering (AML) area requesting an ETL process to populate a new AML system.

Increasing regulation means that organisations must be able to demonstrate the quality and trace the origin of the data they use in critical business processes.

In Europe, Solvency II requires insurance and re-insurance undertakings to demonstrate the data they use for solvency calculations is as complete, appropriate and accurate as required for the intended purpose. Other regulatory requirements such as Dodd Frank in the USA, BASEL III and BCBS 239 are also seeking increasing transparency regarding the quality of data underpinning our financial system.

While regulation may be a strong driving force for providing standard data content facts, an even stronger one is the business benefit that to be gained from being informed.  Some time ago Gartner research showed that approximately 70% of CRM projects failed.  I wonder were the business owners of the proposed CRM system shown data content facts about the data available to populate the proposed CRM system?

In years to come, we will look back on those crazy days when data consumers were not shown data content facts about the data they were consuming.

What is your undertaking-wide common understanding of data quality?

Do you have an undertaking-wide common understanding of data quality?  If not – I suggest you read on…

When a serious “data” problem arises in your organisation, how is it discussed? (By “serious”, I mean a data problem that has, or could cost so much money that it has come to the attention of the board).

What Data Quality KPIs does your board request, or receive to enable the board members understand the problem with the quality of the data? What data quality controls does your board expect to be in place to ensure that critical data is complete, appropriate and accurate?

If your board has delegated authority to a data governance committee, what is the data governance committee’s understanding of “Data Quality”?  Is it shared across your organisation?  Do you all speak the same language, and use the same terminology when discussing “Data Quality”?  In brief – are you all singing from the same “Data Quality Hymn Sheet”?

Why do I ask?

Solvency II – What is your undertaking wide common understanding of Data Quality?

For the first time, a regulator has stated that organisations must have an “undertaking-wide common understanding of data quality”.

Solvency II requires insurance organisations to demonstrate the data underpinning their solvency calculations are as complete, appropriate and accurate as possible.  The guidance from the regulator goes further than that.

CP 56, paragraph 5.178 states:  “Based on the criteria of “accuracy”, “completeness” and “appropriateness”… the undertaking shall further specify its own concept of data quality.  Provided that undertaking-wide there is a common understanding of data quality, the undertaking shall also define the abstract concept of data quality in relation to the various types of data in use… The undertaking shall eventually assign to the different data sets specific qualitative and/or quantitative criteria which, if satisfied, qualify them for use in the internal model.”

Business Requirements should be clear, measurable and testable. Unfortunately, the SII regulator uses complex language, that make SII Data Quality Management and Governance requirements wooly, ambiguous and open to interpretation.  My interpretation of the guidance is that the regulator will expect you to demonstrate your “undertaking-wide common understanding of data quality”.  

What might a common understanding of data quality look like?

Within the Data Quality industry, commonly used dimensions of data quality include.

  • Completeness
    Is the data populated ?
  • Validity
    Is the data within the permitted range of values ?
  • Accuracy
    Does the data represent reality or a verifiable source ?
  • Consistency
    Is the same data consistent across different files/tables ?
  • Timeliness
    Is the data available when needed ?
  • Accessibility
    Is the data easily accessible, understandable and usable ?

Little did I know at the time I wrote the above blog post that a regulator would soon require organisations to demonstrate their understanding of data quality, and demonstrate that it is shared “undertaking wide”.

How might you demonstrate that your understanding of data quality is “undertaking-wide” and “common”?

You could demonstrate that multiple “data dependent” processes have a shared understanding of data quality (processes such as CRM, Anti Money Laundering, Anti Fraud, Single View of Customer etc.)

In the UK, the Pensions Regulator (tPR) has issued record keeping requirements which requires pensions companies to measure and manage the quality of their schemes data.  I believe the Solvency II “independent third party” will at least expect to see a common understanding of data quality shared between Solvency II and tPR programmes.

Data Governance – Did you drop something?

Welcome to part 5 of Solvency II Standards for Data Quality – common sense standards for all businesses.

Solvency II Data Quality - Is your data complete?

Solvency II Data Quality – Is your data complete?

I suspect C-level management worldwide believe their organisation has controls in place to ensure the data on which they base their critical decisions is “complete”. It’s “applied common sense”.

Therefore, C-level management would be quite happy with the Solvency II data quality requirement that states: “No relevant data available is excluded from consideration without justification (completeness)” (Ref: CP 56 paragraph 5.181).

So… what could go wrong?

In this post, I discuss one process at high risk of inadvertently excluding relevant data – the “Data Extraction” process.

“Data Extraction” is one of the most common business processes in the world.  Data is commonly “extracted” from “operational systems” and fed into “informational systems” (which I refer to as “End of Food Chain Systems”).  Data Extraction is usually followed by a “Data Transform” step to prepare the data for loading into the target system. I will discuss “Data Transformation” risks in a later post.

If the data extraction can be demonstrated to be a complete copy – there is no risk of inadvertently omitting relevant data. Few data extractions are complete copies.

In most instances, data extractions are “selective”.  In the insurance industry for example, the selection may be done based on product type, or perhaps policy status.  This is perfectly acceptable – so long as any “excluded data” is justified.

Over time, new products may be added to the operational system(s). There is a risk that the data extraction process is not updated, the new products are inadvertently excluded, and never make it to the “end of food chain” informational system (CRM, BI, Solvency II, Anti-Money Laundering, etc.)

So… what can be done to manage this risk.

I propose a “Universal Data Governance Principle” – namely: “Within the data extraction process, the decision to EXCLUDE data is equally important to the decision to INCLUDE data.”

To implement the principle, all data extractions (regardless of industry) should include the following control.

  1. Total population (of source data)
  2. Profile of source data based on the selection field (e.g. product type)
  3. Inclusion selection list (e.g. product types to be included)
  4. Exclusion selection list (e.g. product types to be excluded) – with documented justification
  5. Generate an alert when a value is found in the “selection field” that is NOT in either list (e.g. new product type).
  6. Monitor the control regularly to verify it is working
So – ask yourself – Can you demonstrate that your “data extractions” don’t overlook anything – can you demonstrate that “No relevant data available is excluded from consideration without justification (completeness)”?
Feedback welcome – as always.
