Study Notes
System Development Life Cycle (SDLC)
- SDLC is a conceptual model that includes policies and procedures for developing or altering systems throughout their life cycles.
- SDLC is a systematic approach that breaks down the work into phases required to implement new or modified Information Systems.
Phases of SDLC
- Planning
- Analysis
- Design
- Implementation
- Maintenance
Planning
- Feasibility studies are undertaken to determine whether a project is viable.
- Feasibility studies help determine if a company has enough money for a project, if the product will sell, and if there are enough human resources.
- A good feasibility study shows the strengths and deficits before the project is planned or budgeted for.
Types of Feasibility Studies
- Technical Feasibility Study: assesses an organization's technical resources to determine if they meet capacity and if the technical team can convert ideas into working systems.
- Economic Feasibility Study: determines whether the required software is capable of generating financial gains for an organization.
- Operational Feasibility Study: assesses the extent to which the required software performs a series of steps to solve business problems and user requirements.
Analysis
- The purpose of the systems analysis phase is to understand business requirements and build a logical model of the new system.
- Requirements determination involves studying the existing system and gathering details to find out what the requirements are, how it works, and where improvements should be made.
- Requirements investigation involves studying the current system and documenting its features for further analysis.
