A). Incremental Model

B). Concurrent Development Model

C). WINWIN Spiral Model

D). All of the above

Show explanation Expand Question

All of the listed models are evolutionary; hence 'All of the above' is correct.

Question 44

The software life cycle can be said to consist of a series of phases. The classical model is referred to as the waterfall model. Which phase may be defined as 'The concept is explored and refined, and the client’s requirements are elicited'?

A). Requirements

B). Implementation

C). Design

D). Specification

Show explanation Expand Question

The Requirements phase is where the client’s requirements are elicited.

Question 45

How is WINWIN Spiral Model different from Spiral Model?

A). It defines tasks required to assess both technical and management risks

B). It defines tasks required to construct, test, install, and provide user support

C). It defines tasks required to define resources, timelines, and other project related information

D). It defines a set of negotiation activities at the beginning of each pass around the spiral

Show explanation Expand Question

WINWIN Spiral Model includes negotiation activities at the beginning of each loop.
