True or False: In practice, requirements engineering is a strictly sequential process — each of the four high-level activities (feasibility study, elicitation and analysis, specification, validation) is fully completed before the next one starts.
Correct Answer
False
Explanation
In practice, requirements engineering is an iterative process in which the activities are interleaved, not strictly sequential. The activities are organized as an iterative process around a spiral. The amount of time devoted to each activity in each iteration depends on the stage of the process and the type of system being developed.
