what is the reference for this uirements, design, implementation, verification, and maintenance. Each phase must be completed before the next one begins, which ensures a clear and organized approach. Thorough Planning: In hardware projects, thorough planning and design are crucial because changes later in the project can be very costly. The Waterfall model emphasizes detailed documentation and planning upfront, which helps in identifying potential issues early. Minimizing Changes: Once the design phase is completed and approved, the project moves to the implementation phase. This reduces the likelihood of changes during the manufacturing process, which can be expensive and time-consuming in hardware projects. Clear Milestones: The sequential nature of the Waterfall model provides clear milestones and deliverables at each phase. This is particularly important in hardware projects where each phase might involve different teams and specialized equipment. Risk Management: By addressing all requirements and design aspects before implementation, the Waterfall model helps in identifying and mitigating risks early in the project lifecycle. Documentation: The emphasis on documentation in the Waterfall model ensures that all aspects of the project are well-documented, which is essential for hardware projects that may require detailed specifications and compliance with industry standards. In summary, the Waterfall model's
