The phase of the SDLC when the system is actually built or purchased is the ________________.a.designb.constructionc.implementationd.analysis

Breakdown the Problem

1. Identify the phases of the Software Development Life Cycle (SDLC).
2. Determine which phase corresponds to building or purchasing the system.

Relevant Concepts

• Design Phase: Involves planning and designing how the system will work.
• Construction Phase: Sometimes referred to as "development," where coding occurs to create the software.
• Implementation Phase: The phase where the system is actually deployed and made operational.
• Analysis Phase: Involves gathering requirements and analyzing needs.

Analysis and Detail

• The options are referring to specific phases of SDLC:
  • a. Design: Focuses on how the system will function.
  • b. Construction: This phase involves the coding and actual building of the system.
  • c. Implementation: The system is deployed to users, but not necessarily when it is built or purchased.
  • d. Analysis: This phase comes before the construction phase, focusing on requirements.

Verify and Summarize

Given the definitions and roles of each phase, it's clear that the phase where the system is actually constructed or purchased aligns more closely with the b. Construction phase.

Final Answer

The correct answer is b. construction.
