Enhancing ISO/IEC 15288 with reuse and product management: An add-on process reference model

•Extension of ISO/IEC 15288 with system level reuse and product management processes•Provision of process reference model conformant to requirements of ISO/IEC 15504•Reference framework for process assessment and improvement in systems engineering•Support for transformation of systems engineering towards use of ‘system products’

To support the transformation of system engineering from the project-based development of highly customer-specific solutions to the reuse and customization of ‘system products’, we integrate a process reference model for reuse- and product-oriented industrial engineering and a process reference model extending ISO/IEC 12207 on software life cycle processes with software- and system-level product management. We synthesize the key process elements of both models to enhance ISO/IEC 15288 on system life cycle processes with product- and reuse-oriented engineering and product management practices as an integrated framework for process assessment and improvement in contexts where systems are developed and evolved as products.
