Question

Match each software lifecycle model in List – I to its description in List – II :

$\begin{array}{clcl}  \text{} & \textbf{List-I} && \textbf{List-II} \\ \text{I.} & \text{Code-and-Fix} & \text{a.} & \text{Assess risks at each step; do most critical} \\ &&& \text{action first} \\ \text{II.} & \text{Evolutionary} & \text{b.} & \text{Build an initial small requirement specifications,} \\ &&&\text{code it, then “evolve” the specifications and code} \\ &\text{Prototyping}&& \text{as needed}  \\  \text{III.} & \text{Spiral} & \text{c.} & \text{Build initial requirement specification for several}\\ &&& \text{releases, then design-and-code in sequence}  \\ \text{IV.} & \text{Stagged delivery} & \text{d.} & \text{ Standard phases (requirements, design, code, test)} \\&&&\text{in order}  \\ \text{V.} & \text{Waterfall} & \text{e.} & \text{Write some code,debug it, repeat(i.e. ad-hoc)} \\  \end{array}$

$\textbf{Codes :}$

• A. $\text{I-e, II-b, III-a, IV-c, V-d}$
• B. $\text{I-e,II-c, III-a IV-b, V-d}$
• C. $\text{I-d, II-a, III-b, IV-c, V-e}$
• D. $\text{I-c, II-e, III-a, IV-b, V-d}$

Answer 1

ans should be A

Code-and-Fix------->Write some code, debug it, repeat (i.e. ad-hoc)

Evolutionary prototyping--->Build an initial small requirement specifications, code it, then “evolve” the specifications & code as needed

Spiral------>Assess risks at each step; do most critical action first.

staged delivery--->. Build initial requirement specification for several releases, then design-and-code in sequence

Waterfall  --------->Standard phases (requirements, design, code, test) in order
