Comparing SPiCE for Space (S4S) and CMMI-DEV: Identifying Sources of Risk from Improvement Models

Abstract

This paper analyses the differences between SPiCE for Space (S4S) snd CMMI-DEV v1.3. S4S (ECSS-Q-HB-80-02) is the software process assessment model used by the European Space Agency (ESA) based on ISO/IEC 15504-2 and the process reference model ISO/IEC 15504-5. CMMI-DEV, widely used in the United States and adopted by companies worldwide, is a requirement for subcontractors working for NASA projects. This means that companies in the aerospace sector need to demonstrate compliance with the requirements and practices described in both models. The objective of this paper is to identify the gap in the base practices proposed in S4S and CMMI-DEV. This analysis of differences is necessary, as long as the gaps between these models can translate into potential risks for those companies focused just on one of the models. European aerospace companies must deal with the need of working and being assessed from two different perspectives: S4S and CMMI-DEV. Getting a detailed picture of the differences between these models may help companies focus their improvement strategies and avoid potential pitfalls when being assessed. © Springer-Verlag Berlin Heidelberg 2013.
