Question

Explain any five advantages and five disadvantages of plan driven development.

Answer 1

Plan-driven development offers the advantages of clear goals, predictability, well-defined requirements, controlled change, and traceability. However, it has drawbacks such as rigidity, time-consuming planning, limited customer engagement, increased project risk, and reduced creativity and innovation.

Step-by-step explanation:

Advantages of plan-driven development:

1. Clear project goals and objectives: A plan-driven approach helps establish clear goals and objectives for the project, providing a roadmap for the development process.
2. Predictability: With a thorough plan in place, it becomes easier to estimate timelines, budgets, and potential risks, making the development process more predictable.
3. Well-defined requirements: A plan-driven approach places emphasis on gathering and documenting requirements early in the development cycle, minimizing ambiguity and ensuring a solid foundation for the project.
4. Controlled Change: By following a plan, changes to the project can be controlled and managed more effectively, reducing the risk of scope creep and ensuring better quality control.
5. Traceability: Plan-driven development allows for thorough documentation and traceability, making it easier to track progress, identify issues, and validate results.

Disadvantages of plan-driven development:

1. Rigidity: A plan-driven approach can be inflexible, making it difficult to adapt to changing requirements or unforeseen circumstances.
2. Time-consuming: Creating a comprehensive plan can take a significant amount of time and effort, potentially delaying the start of actual development work.
3. Lack of customer engagement: In a plan-driven approach, customer involvement and feedback may be limited, resulting in a potential mismatch between the final product and customer expectations.
4. Increased project risk: Relying solely on a plan can increase the risk of failure if assumptions or predictions prove to be inaccurate.
5. Less creativity and innovation: Strict adherence to a plan may stifle creativity and limit the exploration of alternative solutions.
