Which of the following is/are the phases of system development life cycle?

  1. A.Implementation
  2. B.Feasibility study
  3. C.All of the options
  4. D.Coding

Correct answer

C. All of the options

Explanation

The correct answer is C, All of the options. The system development life cycle, or SDLC, is the set of stages followed while building a software system, and feasibility study, coding and implementation are all stages of it. The usual order is preliminary investigation and feasibility study, then requirement analysis, then system design, then coding or development, then testing, then implementation, and finally maintenance. The feasibility study checks whether the proposed system is workable in technical, economic and operational terms before money is spent; coding turns the design into program instructions; implementation installs the finished system and moves users onto it. A, B and D are each wrong only because they name a single stage, while the question asks which of them belong to the life cycle and all three do. Exam tip: remember the SDLC order as feasibility, analysis, design, coding, testing, implementation, maintenance.
