Tool for usage of multiple process assessment models

Abstract

CMMI and ISO/IEC 15504 are two main models for software process assessment and improvement. Both models have staged and continuous representations but these are different. It is desirable for organizations to have assessments according to more than one model but every assessment is expensive both financially and time-wise. Furthermore, a new assessment is required when a new model’s version is released. Transitional Process Assessment Model (TPAM) is proposed as tool supporting these opportunities. It enables assessment results according to one Process Assessment Model (PAM) to be transformed to other PAMs. The requirements and the main principles of TPAM construction have been presented in [1, 2]. This paper details the methodology for inclusion of a new model into TPAM and presents application of this methodology for CMMI-DEV V1.3 and ISO/IEC 15504-5:2012 inclusion. It has been concluded that TPAM is a suitable tool for usage of multiple PAMs.
