Thesis Abstract :

Small and Medium-sized Enterprises (SMEs) from different business sectors, that are certified by some standardization organizations, are increasingly prioritizing the process improvement to raise their product’s quality. The process improvement in SMEs has focused principally on the refinement of existing processes to improve what is currently done through the application of previously developed tools and techniques. This thesis study describes the application of Soft Systems Methodology (SSM) for engineering design process improvement in a SME that has the certification of Capability Maturity Model Integration (CMMI). The SSM uses systems thinking in a cycle of action research and learning to help understand the various perceptions that exist in the minds of different people involved in the problematic situations. In the concept of thesis study, it will lead to identify problematic situations about design process and its sub-processes by involving the human, social and cultural factors besides the technical factors. This thesis study includes four case studies of SSM’s use to analyze the sub-processes of design process named as Requirements Management, Technical Solution, Integration, Verification and Validation sub-processes. There are seven stages of SSM and they are applied to design process and its sub-processes except the stage seven, implementation stage. The rich pictures of sub- processes are drawn based on gathered data from semi-structured interviews and then the root definitions are defined by using CATWOE rule. The conceptual models are built for sub- processes and they are compared with real world activities to address the proposed changes. The outcomes of the study will show how the rich pictures, root definition and conceptual models approaches of SSM can help to identify the problematic situations and address the proposed changes.
