Question
1. Can you tell by looking at a single specification statement in isolation whether it is a requirement or (engineering) design specification? How, or why not? 2. Suppose we are designing a smart pillbox that dispenses the correct dose of medication when it needs to be taken. Write three user-level requirements for such a product. 3. Draw an activity diagram of your choosing to illustrate the process of designing with use case models. Provide enough details and description, and use a drawing tool to create the diagramExplanation / Answer
Ans-1 ) In principle, any statement could appear in either a requirement specification or design specification because given a specification, a scenario can be constructed in which it expresses a client need, or a scenario can be constructed in which it states an engineering design directive. In practice, however, most statements about a product's features/capabilities are requirement specifications, and most statements about implementation are design specification.
