The presentation will show how Root Cause Analysis (RCA) can be applied in way that it supports reaching the business goals of an organisation. It is based on collected data of RCA sessions (done for several years) and the impact on business results, and analysing this data together with non-quantitative information. This has lead to effective RCA methods, applied at specific points in the processes, with significant business results.

Also the role of RCA in Total Quality Management and Statistical Process Control is explained, including how RCA used results from Orthogonal Defect Classification for maximum result. Finally, RCA as a pragmatic implementation of the CMMI Causal Analysis & Resolution process area, is elaborated.
