Systems Engineering is an interdisciplinary and holistic discipline with methods and techniques to address complex problems. This paper proposes an integration of system life-cycle processes and stages from ISO/IEC 15288 with the proposed tools-model framework as a basic framework, allowing team to generate data, define customer needs, optimize solutions, architecture the system, make decisions, validate, analyze failures, and realize the system. This paper gives a short presentation of tools-model framework application on a real case in industry. The application of this proposed model led to a significant increase of the firm total and (labors, materials) partial productivity, qualityproductivity index, profit, and value added almost by (39%, 65%, 20%, 39%, 202%, and 119%) respectively, noticeable positive decrease of defective products percentage, downtime, rework, and lead time almost by (79%, 28%, 98%, and 80%) respectively, also acquiring new customers and new products, besides developing training programs, and solving customer claims
