Which one is not a phase of the systems development life cycle?

Correct option is B

Decision analysis is not a phase in the traditional Systems Development Life Cycle (SDLC). The Systems Development Life Cycle (SDLC) typically includes the following phases:
· Planning: Defining the project scope, goals, and resources.
· Requirements Analysis: Gathering and documenting functional and non-functional requirements.
· Design: Creating the architecture and design of the system.
· Implementation or Coding: Writing the actual code for the system.
· Testing: Verifying that the system meets the specified requirements.
· Deployment: Releasing the system into the production environment.
· Maintenance: Providing ongoing support and updates to the system.
· Post-implementation Review: Evaluating the project's success and identifying areas for improvement.
Decision analysis, while important, is a technique used in project management and business analysis, not a defined SDLC phase.
Important Key Points:
1. SDLC Phases: Involves specific stages like problem identification, requirements gathering, designing solutions, implementation, and testing.
2. Exclusion of Decision Analysis: While decision analysis supports project management, it is not part of SDLC’s structured phases.
Knowledge Booster:
· Problem Analysis: Defines the issue that needs to be solved through the system.
· Requirements Analysis: Collects and documents the system's requirements.
· Post-Implementation Review: Evaluates the success of the system after deployment.
· Scope Definition: Determines what the project will and will not include, an important early step in SDLC.
