This paper aims to propose the principles of a systems architecting method to assess and guide the conceptual design of platform based solutions for satellite space applications. The method helps the developers to assess the platform changeability to achieve future missions with a minimum impact in terms of modifications and to assess the platform comprehensiveness in terms of possible missions...

Changeability (also called evolvability) is an essential property of software. Software change is the foundation for both new software development and legacy software maintenance, therefore a better understanding of software change is an important software engineering issue. This paper covers selected topics related to software change, including minicycle of change, partitioned annotations, and...
