applied to the methodology at the levels of key process areas (KPAs) and key
performance indicators (KPIs). These pieces are necessary in order to understand and
define what the business processes are and should be around the implementation and life
cycle of the business intelligence build-out.

The business of building business intelligence solutions needs to mature. In order to
accomplish these goals, the implementation team must first accept that a BI system is a

software product. As such, software development life cycle (SDLC) components, along
with best practices of managing, identifying, measuring, and optimizing must be applied
—particularly if the team is to become and remain agile going forward. Fig. 6.4.2
demonstrates how CMMI levels map to Data Vault 2.0 methodology. It is not a complete
map, just a representative portion of the entire piece.

The end goal of CMMI is optimization. Optimization cannot be achieved without metrics
(quantitative measurements) or KPIs. These KPIs cannot be achieved without the KPAs
or definitions of key areas to be measured, which of course cannot be achieved without
