  • . The phases of this methodology are completed one after another in the following order:Requirements elicitation
  • DesignImplementation
  • VerificationMaintenance.
  • Each of these steps should be completed and fully documented before the next step is taken. This linear approach is most known for the following characteristics:Rigid structure

Comprehensive documentation

Each phase in the waterfall process must be completed before the next phase can begin. This approach ensures that all necessary documentation is created and minimises the risk of overlooking important requirements. It can be inflexible if requirements change mid-project. The

sequential nature of waterfall requires meticulous planning and clear communication throughout the development lifecycle. Benefits of the waterfall method

Waterfall project management is a sequential and linear approach to executing tasks, and it has several advantages. Let’s discuss each one of them:

Clear project structure and timeline

The

sequential nature

of waterfall provides:

Phases with clearly defined start and end points

A planned structure with a timeline for when the work is to be completed

Milestones that are easily communicated to stakeholders.

Comprehensive documentation

Waterfall methodology advocates comprehensive documentation, leading to well-defined project requirements and specifications, detailed design documents for future reference and valuable historical records for similar projects. Predictable costs and resource allocation The upfront planning involved in the waterfall model allows for accurate budget estimation, efficient resource allocation throughout the project lifecycle and minimised unexpected expenses.

Easier tracking and progress assessment

Waterfall’s structured approach facilitates easy tracking of progress with clear indicators at each phase, simplified reporting to stakeholders and easy identification of bottlenecks or delays.

Reduced risk through upfront planning

Upfront planning in waterfall can help:

Identify potential risks early in the project

Develop mitigation strategies before the work commences

Minimise costly changes during the later stages of the project.

These strengths make waterfall ideal for projects with clearly defined requirements and relatively few changes expected. The methodology’s robustness is also very appropriate to the complexity of the work and the need for strict and complete control of change for medical device software development.
