How many times have you been asked by a key stakeholder like project manager, senior manager, development manager etc. about a number of defects that are left in a product? Or about a number of faults that you are going to detect in future e.g. in the following week of testing? What was your`s response? How do you handle with this complex problem?
During the presentation, four different approaches, that will help to deal with it, will be demonstrated and explained: 1.Empirical.
4. ‘For the poor’.
Empirical approach bases on the importance of feedback measured during SIT testing and latent defects. The results are transformed into a correlation curve that shows possible number of defects that will be detected after a release. Modeling is about simulating defects injection curve that allows to monitor and control on-going defects detection. Statistical approach refers to usage of Weibull analysis that shows a possible projection of defects` arrival curve. ‘For the poor’ is a way that can used by any project without the necessity to provide detailed data or specific knowledge. The goal of the speech is to share ideas that will allow participants to give a reasonable and informative response to the question.
