Question
According to the document, which of the following is a key deficiency of the Waterfall Model regarding flexibility?
Correct Answer
Option A is the correct answer.
Detailed Explanation
Page 37 explicitly states, "All requirements must be known upfront" and "Deliverables created for each phase are considered frozen - inhibits flexibility" as key deficiencies of the Waterfall Model. This rigidity in defining requirements early reduces flexibility.
Hint
Consider how early, rigid requirement definition impacts the model's ability to adapt to changes.
