1.1 - Data Governance challenge in a simple theoretical model
Data are transferred, stored, extracted,
prepared, calculated and reconciled several
times before being reported. A long and risky
journey !
Information presented in report G depends on succession of embedded transformations
Quality of G = Quality of [t6(t5(t4(t3(t2(t1(data in operational system A)))))))]
Substantial part of data may be lost or deteriorated during the process !

Internal risk : availabiliy of right information for management decisions
External risk : inconsistent reporting to third parties

2.4 - Issue Management
Importance:
– Data Quality issues must be fixed as early in the data logistical chain as possible as the graph below
will show
– Studies prove that the costs grow exponentially while data progress through the data logistical chain
Goal: solutions, not issues
Process:
As Data Quality is being analysed and checks are performed issues will be identified. The issues are
addressed by the Issue Management Team (part of DQCC) in cooperation with the domains. All issues are
given a priority, a deadline and addressed to an action owner.
Tools:
– Formalized Issue Management process
– Quality Centre: A tool in which DQ issues are logged and managed
– Prioritisation Tool: A tool which is used to prioritise the DQ issues
– Issue Management Process Guideline: A guideline for the domains how they could set up their own
Issue Management Framework

I. The monthly calculated RWA/EC is volatile; This is not the result of a changed risk profile, but due to Data Quality defects
as a result of changes in systems, reference tables and changes in the business and so on.
II. Many of the irregularities are manually corrected, which results in a more stable monthly reported RWA/EC. Due to the
“defaulting” rules is line II lower than line I. However these corrections are often not robust, opaque and could lead to
incompliance.
III. The real RWA only changes as a result of changes in the risk profile of ABN AMRO. The real RWA is lower than the
reported RWA, because many Data Quality issues can only be solved by means of changes in the system- and IT-
infrastructure and not by manual corrections.
Goal: Aligning of calculated and reported RWA/EC with the real RWA/EC

Module 1: Launch data
quality actions in the local
systems
Module 2: Measure the data
quality sourced in the
collector & feedback to the
sources
Module 3 : Define common
measures (thermometers &
KPI’s) across the chain(s)
Module 4: Create an
aggregated multi-sources
/multi-periods reporting
environment
Module 5: Challenge the
results produced in the
chains
Module 6: Industrialize the
production of the
deliverables (reports,
referential, distribution)
Module 7: Industrialize the
DQ analysis & follow-up of
issues

Module 7’ upgrade:
Industrialize the DQ

Effective DQ can
help organisation
to forecast their
future potential
states.
