Program Development Life Cycle

The program development life cycle is a structured approach to creating software.
It consists of stages: Analysis, Design, Coding, Testing, and Maintenance.
Each stage produces outputs that feed into the next stage.

Analysis

The analysis stage aims to precisely understand the problem the program must solve.
Abstraction is used to remove unimportant details and focus on core functionality and requirements.
A requirements document is created, defining each requirement with a description and success criteria.
Example of abstraction: London Underground map – shows connections, not geographical accuracy.

Design

The design stage produces a blueprint for the solution.
Design can be presented using structure diagrams, flowcharts, or pseudocode.
The design must match the requirements from the analysis stage.

Coding

Developers write code in a suitable programming language, creating modules that work together.
Iterative testing is performed: each module is tested and debugged as it is built.
Modules are retested when new modules are added to ensure correct interaction.

Testing

The complete program is run many times with varying sets of test data.
Testing ensures the program works as intended and rejects invalid input.
Example test data: alphanumeric sequences for password validation.

Maintenance

After delivery, the program may need updates to fix bugs or add features.
Maintenance ensures the program continues to meet user needs.
