Small organisations have been applying several quality approaches such as CMMI-DEV or ISO/IEC 15504-5 with quite diverse results. In order to build an experience factory we are gathering our experiences in a database containing the assessment results of more than 90 initiatives. This paper provides an empirical comparison of survival analysis for different improvement initiatives in the context of very small entities. We compare the Cox Proportional Hazard Regression models of our 90 initiatives, and we discriminated them by the reference model used: ISO/IEC29110, CMMI-DEV or ITMark.
