Show answer & explanation
Correct answer: A
Concept
An initialism is expanded by mapping each letter to a word in the accepted term for the stated subject area. The subject-area qualifier matters because one initialism can have more than one established expansion in different technical contexts.
Application
Here the subject area is systems analysis and design, so the system-development terminology is the relevant convention.
Letter | Term |
|---|---|
S | System |
D | Development |
L | Life |
C | Cycle |
The mapped expansion is System Development Life Cycle. It denotes the full span of activities associated with a system, from initiation and development through operation, maintenance, and retirement.
Contrast
Software Data Life Cycle changes D to Data and describes a data-centred phrase.
Software Design Life Cycle changes D to Design and narrows the phrase to software design.
System Design Life Cycle also changes D to Design and narrows the phrase to system design.
Cross-check
NIST recognises System Development Life Cycle as an SDLC expansion for the lifecycle of a system. Software Development Life Cycle is also an established expansion in software-engineering contexts, which explains the learner’s concern, but that wording is not among the offered choices; the systems-analysis qualifier makes System Development Life Cycle the applicable offered expansion.
