A model for deploying life‐cycle process standards in the change management of complex systems

A model for deploying international systems and software life‐cycle process standards within large organizations/enterprises is presented. The model defines a limited number of actor (stakeholder) categories and identifies their roles and responsibilities in respect to the change management of complex systems. While the main thrust of this paper is related to process deployment, the need for achieving balance between the system related key aspects of architecture, processes, methods and tools, organization, and competence is emphasized. Principles for the integration of systems as aggregates of entities (components, tasks, and other aggregates) are presented. An “agreement pipe” abstraction is introduced to conceptualize the flow of products and services between model actors. The importance of centralized intelligence and support functions is considered. Finally, the means of instrumentation of the model via international system and software life cycle process standards is presented and illustrated via an adaptation (tailoring) of the development process from ISO/IEC 12207.
