The program development lifecycle 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 setting 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 program is planned out in detail. This includes creating a blueprint of the program's structure, as well as designing the user interface and any other visual elements.
4. Implementation: This is the stage where the actual coding of the program takes place. Programmers write the code according to the design specifications, and test it to ensure that it functions correctly.
5. Testing: In this stage, the program is thoroughly tested to identify and fix any bugs or errors. This includes both unit testing (testing individual components of the program) and integration testing (testing how the components work together).
6. Deployment: Once the program has been thoroughly tested and approved, it is ready to be deployed to the end users. This may involve installing the program on individual computers, or making it available for download online.
7. Maintenance: After the program has been deployed, it is important to continue to maintain and update it as needed. This may involve fixing bugs, adding new features, or making other improvements based on user feedback.
By following these stages of the program development lifecycle, developers can ensure that the program is developed efficiently and effectively, meeting the needs of both the users and the organization.

Program Development Lifecycle (PDLC)
The PDLC is a structured and iterative process that guides the development and maintenance of software applications. It consists of the following stages:
1. Planning
- Define project goals and objectives
- Identify stakeholders and requirements
- Create a project plan and timeframe
- Establish development methodology and tools
2. Analysis
- Gather detailed requirements from stakeholders
- Document and validate requirements
- Analyze system functionality and data structures
- Define system architecture and interfaces
3. Design
- Create technical specifications and design documents
- Develop system architecture and components
- Implement design patterns and algorithms
- Design user interfaces and databases
4. Implementation
- Code the software application
- Create unit and integration tests
- Conduct code reviews and testing
- Integrate and deploy the application
5. Testing
- Perform unit, integration, and system testing
- Verify that the application meets requirements
- Identify and resolve defects
- Conduct user acceptance testing
6. Deployment
- Release the application to production
- Install, configure, and test the application
- Train users on the application
- Monitor and maintain the application
7. Maintenance
- Address performance issues and security vulnerabilities
- Implement enhancements and new features
- Apply updates and patches
- Monitor and track application usage
8. Retirement
- Plan for the end-of-life of the application
- Migrate data to a new system or archive it
- Decommission the hardware and software
Key Principles
- Iterative and Incremental: PDLC follows an iterative approach, where requirements are refined and the application is developed incrementally.
- Stakeholder Involvement: Stakeholders are actively involved throughout the process to ensure their needs are met.
- Documentation: Detailed documentation is created at each stage to provide a clear understanding of the project.
- Quality Assurance: Testing and validation are integral parts of the process to ensure the application meets the required standards.
- Continuous Improvement: The PDLC is a cyclical process, where lessons learned are used to improve future iterations.
