To support a data governance initiative, Yapı Kredi needed a tool to define common business terms and to help its data stewards and data managers to collaborate.
Yapı Kredi created a business glossary to support its business metadata management processes. The bank can now store “golden source” data, up-to-date data definitions and data quality rules.

Business challenge story
Seeking to improve data governance
In 2015, Yapı Kredi began a strategic data governance initiative. Data governance has become increasingly important over the years for several reasons, particularly for highly regulated industries such as banking, according to Bora Üzüm, Vice President, Data Governance Office, Yapı Kredi. Consumer trust is one of these reasons. In the past, consumers didn’t think twice about sharing personal data. But with so many stories in the news about data leaks and improper data usage, consumers have become more cautious. “As a company, you have to brand yourself as a trustworthy data steward,” says Üzüm. “Data privacy and governance are very important.”
Reliable analytics are another reason data governance is essential. If you want to achieve meaningful results from your analytics activities, you must have up-to-date, complete and high-quality data in your systems. The effects of bad data in a company’s systems can be negative and far-reaching. “There is a concept called data prejudice,” says Üzüm. “If you put untrustworthy data in your machine-learning practices or analytics procedures, you can be discriminating against certain groups unintentionally. Bad data can have significant real-world consequences.”
Creating a business glossary
To begin its data governance initiative, Yapı Kredi appointed data stewards and data managers and took steps to foster, within the bank, the change needed to support the effort. “We promoted cultural change management through communication and training,” says Üzüm. “We appointed all roles and responsibilities.”
The bank also implemented InfoSphere Information Governance Catalog (IGC) software to support its business metadata management processes. The InfoSphere offering is a web-based tool that provides the business glossary for Yapı Kredi’s data governance approach. Using the InfoSphere Information Governance Catalog solution, the bank can store “golden source” data, up-to-date data definitions, data quality rules and data refreshment policies.
“Data owners and data stewards use the InfoSphere application to define their own business terms in the system; then, according to those definitions, we’re developing automatic systems to measure data quality levels,” says Üzüm. The InfoSphere application is customizable. Yapı Kredi can calculate data quality scores for its business terms, and then load the scores into the Information Governance Catalog application and display them in custom fields. Through integration with its Lightweight Directory Access Protocol (LDAP) server, users can access the InfoSphere application via the bank’s single sign-on system. The bank can also load its HR organizational units into IGC via LDAP, which enables data stewards to grant the appropriate units access to certain business terms.
Getting started with the InfoSphere Information Governance Catalog application was straightforward. “The tool already contains hierarchies, basic universal concepts of data governance and collaboration tools, so it was easy to set up and use,” says Üzüm.
The InfoSphere Information Governance Catalog solution is accessible to employees outside of the IT group. “Our data stewards and data managers aren’t technical. They are from the lines of business, so the tool must be very easy to use for them,” says Üzüm. “It’s a very lightweight, easy to use and easy to understand business data glossary.” InfoSphere Information Governance Catalog software also supports collaboration. Data stewards and data owners can collaborate to approve and publish assets, and the application logs every change.
Finally, the bank anticipates that it will be easier to cope with changing regulations with a data governance strategy in place. “We are protected from regulatory changes central to data management,” says Üzüm. “The banking sector is a highly regulated environment. We must comply with multiple regulations. Without properly identified data responsibilities, it’s impossible to survive.”
