The case study methodology is compatible for many types of software package engineering study, since the objects of study are up to date phenomena, which might be difficult to study in isolation. Case research usually do not crank out the same benefits on e.g. causal interactions as managed experiments do, but they offer deeper idea of the phenomena beneath study.

There's no inhabitants from which a statistically representative sample continues to be drawn. Having said that, for case research, the intention would be to empower analytical generalization the place the final results are extended to cases which have prevalent properties and hence for which the conclusions are relevant, i.e. defining a idea.
2007). It should nevertheless be famous that it generates a considerable volume of data which makes the analysis time consuming.
Samples of presently available information are effort information from older initiatives, income figures of goods, metrics of merchandise good quality concerning failures and many others.
