Chapter 22, Problem 1CQ

To determine

Identify the evaluation processes that are most likely to be part of SDLC step.

Answer to Problem 1CQ

Option b

Explanation of Solution

System Development Life cycle: It is a five step processes used to design and implement new design. The five step processes of SDLC are listed below:

• System analysis.
• Conceptual design.
• Physical design.
• Implementation and conversion and
• Operation and maintenance.

Justification for the incorrect answer:

Option a: System analysis is the first of SDLC in which the information relating to the purchase, develop or modify a system is gathered. These needs are required for developing and documenting system requirements that are used to select or develop new system.

Option c: Physical design is third step in the SDLC that helps in interpreting to the board, user-oriented conceptual design into detailed specification. This step comes to end once the physical system design is communicated to information system directing committee.

Option d: Implementation and conversion is the four step in SDLC were training are provided to employees and existing employees are relocated, when the processing are tested and modified.

Option e: Operation and maintenance is the last step of SDLC, in this step the implemented new system are reviewed periodically and modified as problems arise or new needs become apparent.

Justification for correct answer:

Option b: Conceptual design is second of step of SDLC in which the company decides a way to meet the user’s requirements. This step identifies and evaluates the suitable design alternatives.

Conclusion

Therefore, from the above explanation it is observed that Option b is the correct answer and other options a, c, d and e are incorrect answers.
