  5. 5. EThICSENGINEERING SCR - SYSTEMS CONCEPTS RESEARCH - METHODOLOGYEThICS 039.CE06E.04 INTRODUCTION Ref.: [LIBR_01] Main Concept of SCR The SCR is an organized complex of management and engineering activities, starting from needs and requirements, to obtain the most adequate system concept solution to attain those needs and requirements, considered all the life cycle extent. The SCR method is structured on steps and interactive tasks. It requires the integration of management and engineering activities, during research, development and product assurance, and comprising specialized knowledge and skills on systems, requirements, risks, product assurance, costs and project planning and product development. Depending on the specific conditions of procurement and supply of systems, the work-share between client and manufacturer (or supplier) will vary. Anyway, the complete composition of tasks is practically the same. 9/12/2011 Intellectual Property of EThICS Engineering 5
