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.
