DWH change management
4500 tables,10000 ETL flows (mainframe, RDBMS, flat files), 600 Universes, 25000 reports, ODS, DataMarts, Staging Area “We don’t dare make any
changes to our Data Warehouse”
Our systems have become too complex to understand the interdependencies enough to understand the impact of making changes without tools.

Consistent customer face and preparation for SOA
“We need to be able to access all of a customers information when ever there is an interaction. The days of 'faking it' are over. There needs to be a clear understanding of what all the information that is needed to answer any inquiry, and that information has to be readily available.”

Unlocking SAP metadata
• A customer needed to better understand their data and how to translate that into better business decisions, which is why despite the downturn and cuts in other IT projects, the CIO and CFO saw the investment in PowerDesigner and was one of the few projects not being put on hold as part of their cost reduction plan in response to the financial crisis.
• Works with SAP, Siebel, JDEdwards, PeopleSoft, Oracle Apps
