The program development life cycle consists of several stages that are followed in order to successfully develop a software program. These stages are as follows:
1. Planning: In this stage, the goals and objectives of the program are defined. This includes determining the scope of the program, identifying the target audience, and establishing a timeline and budget for the project.
2. Analysis: During this stage, the requirements of the program are gathered and analyzed. This involves understanding the needs of the end users, as well as any technical requirements that need to be met.
3. Design: In the design stage, the overall structure and architecture of the program are created. This includes creating a detailed blueprint of the program, as well as designing the user interface and any other visual elements.
4. Implementation: The implementation stage involves actually writing the code for the program. This is where the design is turned into a functioning program, with each component being built and tested.
5. Testing: Once the program has been implemented, it is tested to ensure that it functions correctly and meets the requirements that were established in the planning and analysis stages. This includes both unit testing (testing individual components) and system testing (testing the program as a whole).
6. Deployment: In the deployment stage, the program is released to the end users. This may involve installing the program on individual computers, uploading it to a server, or making it available for download.
7. Maintenance: After the program has been deployed, it enters the maintenance stage. This involves fixing any bugs or issues that arise, as well as making updates and improvements to the program as needed.
By following these stages in the program development life cycle, developers can ensure that the program is developed efficiently and effectively, meeting the needs of the end users and achieving the goals of the project.

Program Development Life Cycle (PDLC)
The PDLC is a systematic and iterative process for developing software or computer programs. It consists of the following stages:
1. Planning and Analysis
- Define project scope, goals, and requirements.
- Study the problem domain and identify the system's functional and non-functional needs.
- Conduct feasibility analysis and create a project plan.
2. Design
- Create a detailed system design that outlines the system's architecture, components, and interfaces.
- Implement design patterns, algorithms, and data structures.
- Develop unit tests and integration tests.
3. Implementation (Coding)
- Write the source code for the program using the chosen programming language and tools.
- Enforce coding standards and best practices.
- Conduct unit testing to verify the correctness of individual code modules.
4. Testing and Integration
- Perform integration testing to ensure that the individual modules work together as expected.
- Conduct system testing to verify that the entire system meets the requirements.
- Execute acceptance testing to confirm that the system meets the needs of the end users.
5. Deployment
- Install the program on the target environment (e.g., servers, workstations).
- Configure and set up necessary infrastructure and dependencies.
- Train end users on the system's operation.
6. Maintenance
- Continuously monitor and support the live system.
- Respond to bug reports and user feedback.
- Implement updates, bug fixes, and enhancements to improve the system's functionality and performance.
7. Retirement
- When the program is no longer needed or viable, plan for its decommissioning.
- Archive or dispose of program assets (e.g., source code, documentation).
- Ensure a smooth transition to a replacement system or end-of-life solution.
Iterative and Agile Development
Modern software development approaches, such as Scrum and Agile, emphasize iterative and incremental development. This involves breaking down the PDLC stages into smaller cycles, allowing for frequent feedback and adjustments throughout the process.
