Document Summary

Select representative sample of people and provide motivation for responding. Make sure questions and answers are unbiased and unambiguous. Ask the same things in different ways- check if answers are consistent. Goal: acquire/validate info from concrete examples through narratives. Illustrate typical sequences of interaction among system components to meet an implicit objective. Widely used for: explanation of system-as-is, exploration of system-to-be and elicitation of further info. Storyboards: tells a story by a sequence of snapshots (sentence, sketch, slide, pic etc. ) A running/ seemingly running version of a system/ concrete system used for experimentation/feedback: focus on unclear, hard to formulate requirements. Pros: discover what they need, establishes feasibility at a low cost, detailed study of the reuqirements. Cons: increased development time and cost, misleading (setting expectations too high), incompleteness. Goal: speed up elicitation by reuse of knowledge from experience with related systems. Requirements meta-models: typical things to look for in requirements in a general way.
