Concept:
Software Project Management (SPM) is the discipline of planning, organizing, and managing resources to bring about the successful completion of specific project goals and objectives. It is not a "one-and-done" activity that stops when the code is written.
Step 1: The Scope of Project Management.
A project manager's responsibility spans the entire lifecycle. While Option (B) is a correct activity of project management, Option (D) more accurately reflects the concept of the project lifecycle mentioned in the question prompt. A project is not truly "closed" until the transition to maintenance is complete and the support period is managed.
Step 2: Debunking Incorrect Assumptions.
• Option (A): Planning covers requirements, design, resource allocation, and budget—not just coding.
• Option (C): Risk management is actually one of the most important parts of SPM. Identifying what could go wrong is a core duty.
Step 3: Conclusion on Post-Delivery.
Modern software management follows the "DevOps" or "Agile" mindset where management includes monitoring the software in the live environment, managing updates, and handling support requests. This ensures the long-term success and sustainability of the software.
