Study Notes
Overview of SDLC
- The Systems Development Life Cycle (SDLC) is a project management model outlining stages in an information system development project.
- Stages include initial feasibility study and maintenance of the finished application.
Phases of the SDLC
- Composed of four core phases: Planning, Analysis, Design, and Implementation.
- Each phase comprises steps that yield specific deliverables, aiding in the project's understanding and management.
Planning Phase
- Key process to establish the necessity of an information system.
- Two main steps:
- Project initiation: Identify the system's business value (cost reduction or revenue increase).
- Project management: Create work plans, assemble the team, and implement project control techniques.
Analysis Phase
- Addresses who will use the system, its functions, and deployment specifics.
- Involves investigating current systems, pinpointing improvement areas, and developing new system concepts.
- Contains three steps:
- Analysis strategy.
- Requirements gathering: Leads to the development of analysis models for the new system.
- System proposal: Initial deliverable outlining business requirements for the new system.
Design Phase
- Defines operational aspects such as hardware, software, network infrastructure, user interfaces, and databases.
- Involves five steps:
- Design Strategy.
- Architecture Design.
- Database and File Specifications.
- Program Design.
Implementation Phase
- Focuses on system development or procurement, often the most time-consuming and costly phase.
- Includes three steps:
- System Construction: Building and testing the system to ensure functionality.
- Installation: Preparing to support the newly installed system.
- Support Plan: Incorporates a post-implementation review to assess effectiveness.
System Development Methodologies
- Formalized approaches for implementing SDLC that vary based on emphasis (business processes vs. supporting data).
Methodological Focus
- Process-centered Methodologies emphasize activity definition and system representation as a set of processes with data flow.
- Data-centered Methodologies focus on organizers of data storage and content structuring.
