GATE | GATE-CS-2014-(Set-1) | Question 28

Match the following:

1) Waterfall model        a) Specifications can be
                              developed incrementally

2) Evolutionary model     b) Requirements compromises 
                             are inevitable

3) Component-based        c) Explicit recognition of risk
software engineering

4) Spiral development     d) Inflexible partitioning of 
                             the project into stages

(A)

1-a, 2-b, 3-c, 4-d

(B)

1-d, 2-a, 3-b, 4-c

(C)

1-d, 2-b, 3-a, 4-c

(D)

1-c, 2-a, 3-b, 4-d

Answer: (B)
Explanation:

• Waterfall Model: We can not go back in previous project phase as soon as we proceed to next phase ,So inflexible
• Evolutionary: It keeps changing with evolution so incremental in nature
• Component based: Reuse-based approach to defining, implementing and composing loosely coupled independent components into systems
• Spiral: Spiral model is the most advanced .It includes four faces one of which is Risk.
  • Phases: Planning, Risk Analysis, Engineering and Evaluation
