What are the main advantages of the waterfall model?

The waterfall model is a linear sequential flow that emphasizes a single document reference for each development stage. Its main advantages include:

1. Clear Structure: Each phase has specific deliverables and a review process, which makes the project structure clear and easy to understand.

   • Example: In a software development project, the requirements phase must be completed before moving on to the design phase.

2. Simple Management: Due to its linear nature, the waterfall model is relatively simple to manage and track progress.

   • Example: Project managers can easily monitor the project timeline and ensure that each phase is completed on schedule.

3. Documentation Focus: Emphasis on comprehensive documentation helps in maintaining a detailed record of the project.

   • Example: Detailed requirements documents can be referred to throughout the project lifecycle to ensure consistency.

4. Suitable for Predictable Projects: Ideal for projects where requirements are well-defined and understood by all stakeholders.

   • Example: Building a bridge or a road where the specifications are clear and unlikely to change.

5. Ease of Planning: The sequential nature of the model allows for straightforward planning and resource allocation.

   • Example: Teams can easily estimate the time and resources needed for each phase based on the previous phase's outcomes.

For projects requiring robust documentation and clear phase-wise progression, the waterfall model can be highly effective. In the context of cloud services, platforms like Tencent Cloud offer tools and services that can support structured project management and documentation needs, facilitating efficient implementation of projects following the waterfall model.
