This work presents a method to incorporate the principles of verification and change management in order to address the quality control of engineering artifacts in early stage design. A refined definition of quality is presented and relates design quality to design iteration. A new model, the Decision Pathway Chart (DPC), is introduced to model decisions and iteration. A method and tool for incorporating this DPC model into a process for verifying and managing change through baselining is described and validated based on criteria for evaluating decision-based design methods. The contribution of this work is to introduce a practical technique for implementing quality control principles during design activities that typically lack such rigor toward quality assurance.
