Basel II implementation projects at the largest banks, for example, are exposing significant issues
with respect to the risk infrastructure—including policy, processes, systems, and data quality. Most
organizations are managing to come to grips with their policy, process, and systems requirements,
but data quality remains a signifi cant road block. Complying with Basel II qualification standards
requires a signifi cant history of consistent, accurate, and granular data within the credit
management information systems. Even for some of the smaller banks this involves integrating
information from a wide variety of legacy systems, each with a diversity of data definitions, a
variety of data models, and little understanding of data quality levels.
