1. Understanding the Problem:
- Objective: Gain a clear understanding of the problem or requirement that the software aims to solve.
- Activities: Define the scope, gather requirements, and identify constraints. Establish the goals and objectives of the software.
2. Constructing the List of Variables and Output Design:
- Objective: Define the variables and outputs that the program will use and produce.
- Activities: Identify the necessary data elements, define the input and output specifications, and plan the overall structure of the program.
3. Program Development – Writing Code:
- Objective: Translate the design specifications into actual code.
- Activities: Write the program logic using a programming language, adhering to coding standards and best practices.
4. Compiling, Interpreting, and Debugging:
- Objective: Ensure the code is error-free and ready for execution.
- Activities: Compile the code (for compiled languages), interpret the code (for interpreted languages), and debug any errors or issues.
5. Testing the Program:
- Objective: Verify that the program functions correctly and meets the specified requirements.
- Activities: Execute various tests, including unit tests, integration tests, and system tests. Identify and fix any defects.
6. Documentation and Implementation:
- Objective: Create documentation to facilitate understanding, usage, and maintenance of the program.
- Activities: Generate user manuals, technical documentation, and any other relevant documentation. Implement the program in the target environment.
7. Maintenance:
- Objective: Address issues, make updates, and provide ongoing support to ensure the software remains relevant and functional.
- Activities: Handle bug fixes, implement changes based on user feedback, and update the software as needed to meet evolving requirements.
This structured approach ensures a systematic and organized progression through the various stages of software development. Each stage builds upon the previous one, promoting clarity, efficiency, and the successful delivery of a high-quality software solution. Additionally, feedback loops between stages, especially during testing and maintenance, contribute to continuous improvement and refinement of the software.
