Which of the following is a disadvantage of the SDLC?

The chosen answer points to a significant drawback of the Systems Development Life Cycle (SDLC). SDLC can be resource-intensive, both in terms of financial costs and labor efforts. This is attributed to the structured and sequential approach that involves multiple phases such as planning, analysis, design, implementation, and maintenance. Each phase often requires thorough documentation, stakeholder involvement, and rigorous testing, all of which contribute to increased costs.

In contrast, the other options highlight positive attributes or characteristics that are generally associated with SDLC processes. The flexibility, quick implementation, and ease of change do not typically apply to traditional SDLC frameworks, which tend to follow a rigid structure. Such rigidity can make adjusting to changing requirements or rapid deployment challenging, further emphasizing the validity of the chosen answer regarding the associated costs of implementing SDLC.
