Gathering useful data → Analysing the data → Finding the right requirements
When you collect data it’s very important to have clear goals, a pilot study is in most cases essential. Triangulation is something that we will most likely use in our case study, approaching it from different perspective can help the survey to improve the result. Since we’re doing a case study we will probably both use a direct and an indirect observation. In the case study we will think about problems concerning ethnography (culture point of view), experience sampling and different methods the questionnaires.
When the first pilot study is finished, the next step would probably be deciding how to form the major case study. We will most likely consider the options of how what data we really want. Do we need quantitative data or qualitative data, while graphing the data do we need mean, mode or median?
What’s most important with chapter 10 is the note about requirements is not a wish list. Getting the requirements right can save a lot of money because it’s almost always much cheaper to correct an error early in the development rather than later. The textbook quotes “100 times more expensive” (which is probably in most cases not true)
Question for the seminar: What’s important to think about while defining requirements, since it’s usually something that gets confused.
