Characteristics for the implementation of changeability in complex systems

Abstract: Changeability has become increasingly relevant in the development of complex systems. The definition of system changeability is determined by the ability of the system to change from one state to another in order to overcome encountered changes to deliver and provide for extended value. Considering the dynamic changes encountered in system development and increasing concern over the value of systems, a need to understand which system characteristics should be present to effectively implement changeability is needed. This paper introduces a set of characteristics and elements that are suggested for the implementation of changeability in complex engineering systems based on a systematic literature review. The review showed when properly considered during the concept stage, changeability is an effective approach to deliver active value to systems and architectures.
