Which of the following is one of the six parts of the SDLC?

• A. Debugging
• B. Investigation
• C. Interface design
• D. Project management

Answer: (B)

In the SDLC, projects are organized into stages, and the first stage is often the Investigation (also called feasibility or discovery). This stage concentrates on understanding the problem, talking to stakeholders, gathering what the system needs to do, and checking whether the project is worthwhile and feasible to pursue. It’s about defining the scope and justification before any design or coding happens. That’s why Investigation fits as one of the six main stages: it marks the initial step of understanding and evaluating the project. Debugging is a task that happens later during testing or maintenance, not a separate stage. Interface design is part of the design work within the design phase, not a standalone stage. Project management runs across the lifecycle to plan and monitor work, but isn’t typically listed as one of the discrete stages.
