House of quality in analysis of product development processes

The product development process is subject to randomness of duration of design activities and a path followed through the network of activities. Any feasible schedule of design activities is subject to multiple resource constraints, precedence constraints and temporal constraints. In addition, the design organization may need to undertake multiple projects with different priorities, simultaneously and the availability of resources may change over time. In this paper, the complex relationships between various attributes of the design process and the corresponding design process variables are captured using the house of quality and then transformed into quantitative relationships. The impact of the process control variables on the design process attributes is discussed.
