Examples

The Defect detection Efficiency of the Specification-Quality-Control (SQC) Process is about ‘one Major-Defect found and fixed’ per ‘work-hour invested’. This compares well to the downstream testing and reWork-Processes (Debugging), which are an order-of-magnitude less efficient, and even more, the downstream field rework costs, which are two orders of magnitude less efficient.
Sources: [GILB93, WHEELER96].


Notes

1. A benefit to Cost ratio or a Performance-to-Cost-Ratio would be a Measure of Efficiency.
