5. Arrange the tasks involved in requirements elicitation in an appropriate manner.

I. Consolidation

ii. Prioritization

iii. Requirements Gathering

iv. Evaluation

a) iii, I, ii, iv

b) iii, iv, ii, I

c) iii, ii, iv, I

d) ii, iii, iv, I

View Answer

 

Answer: b

Explanation: Requirements gathering captures viewpoint from different users followed by evaluation of those 

view points. Now comes the task of checking the relative importance of the requirements and finally to 

consolidate or bind together the information collected.
