In the Systems Development Life Cycle, the planning phase includes System Concept Development, Planning, and the Requirements Definition phases.
System Concept Development Phase
- Begins when a sponsor identifies a need or an opportunity to develop, enhance, or acquire an information system.
- Defines the requirement or opportunity, linking it to specific enterprise missions. (This includes a feasibility study and cost-benefits analysis).
- May result in an initiation of a project.
Planning Phase
- Establishes a comprehensive model of the recommended approach to provide better project definition.
- Addresses the concept identified in the Concept Development phase, providing the basis for acquiring the resources needed to achieve a solution.
- Develops a project plan and other planning documents.
Requirements Analysis Phase
- Analyzes user needs and develops user requirements.
- Creates business process model
- Creates a detailed functional requirements document.
- Creates conceptual data model
- Defines inputs, processes, and outputs. Focuses on what functions must be delivered, rather than how to deliver them.
- Serves as the basis for the initial test plan and QA plan.
