Errors in a design process have been recognized as a major source of product quality loss. There are a number of current methods that can be used to identify and quantify these errors including the Design Failure Modes and Effects Analysis and Risk in Early Design. However, these techniques typically do not provide a useful context within which to incorporate the errors identified into the design process in a beneficial way. This thesis proposes that time is a viable metric to measure the impact of errors on the design process. It presents a technique to quantify, in time, the cost of a mistake and proposes a formal approach to determine when it is appropriate to error proof design process steps.
