What is SDLC and name its typical phases?

• A. System Development Life Cycle; phases: Planning, Analysis, Design, Implementation, Verification, Maintenance
• B. Software Development Life Cycle; phases: Requirements, Design, Implementation, Testing, Deployment, Maintenance
• C. System Data LifeCycle; phases: Analysis, Deployment
• D. Software Development Lifecycle; phases: Initiation, Termination

Answer: (B)

SDLC is a framework for delivering software from idea to ongoing support, guiding how work progresses from start to finish. The most accurate option uses Software Development Life Cycle and lists the familiar sequence of phases: Requirements, Design, Implementation, Testing, Deployment, Maintenance. This reflects a clear, logical flow: determine what is needed, plan and design how it will work, build it, verify it works through testing, release it to users, and later maintain and update it as needed. While some variants use System Development Life Cycle, the standard software-focused terminology and the progression shown here align with common practice in many organizations and curricula. Other options mix in terms that aren’t standard for SDLC, such as System Data LifeCycle or phases like Initiation and Termination, which don’t fit the usual software development process.
