Process improvement through Root Cause Analysis

Italtel SIT BUCT Linea UT has been conducting a software process improvement program since 1991, following some of the most widespread paradigms, including: process certification in accordance with ISO 9001, Process Quality Management and Improvement (PQMI), process assessment in accordance with Bootstrap. After four years, the improvement program has brought to tangible quantitative benefits and to the reaching of a stable maturity level 3. Among the lines of actions that have been set up to feed and care the continuous improvement program, a particular emphasis has been put on the experimentation of defect prevention techniques. In this context, a Root Cause Analysis (RCA) program has been implemented, focusing both on failures and on scheduling slippages.
