Rubric: Software Engineering : Factual Claims : Defect Cost Increase : Pressman Ratios

Context

Background: I have been researching quantity and quality of empirical evidence underlying claims in software engineering. What do we know, and how well-established is that? See in particular https://leanpub.com/leprechauns which concludes that the answer is in (too) many cases "not much, and poor".

This applies in particular to the "Defect Cost Increase" claim, which is poorly supported by evidence. The claim states that the longer a defect stays undiscovered after being introduced in a software system's artefacts, the more expensive it is to correct.
