Theories and Tools of Products Development Processes 2

Systems Engineering is a unique approach to problem solving in that it views certain “problems” as parts of an overall system, rather than focusing on individual outcomes and contributing to further development of the undesired element or problem. Systems Engineering is a framework that is based on the belief that the component parts of a system can best be understood in the context of relationships with each other and with other systems, rather than in isolation. The only way to fully understand why a problem or element occurs and persists is to understand the part in relation to the whole. This course will start discussing what system engineering approaches ar in general. Then we will apply them for designing home appliances to understand appliances as whole systems, and relationships between components to system and components to components.
