System design

Based on the requirements, the team designs the system architecture, user interface, database schemas, and detailed technical specifications. Implementation During this phase, developers write code according to the design specifications, adhere to coding standards and best practices, and create unit tests for individual components.

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

of waterfall requires meticulous planning and clear communication throughout the development lifecycle.

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 completedMilestones 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.

The upfront planning involved in the waterfall model allows for accurate budget estimation, efficient resource allocation throughout the project lifecycle and minimised unexpected expenses.

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.Enhance your skills with our expert-led courses

Limitations of the waterfall method

The waterfall method is a structured approach to

project management that follows a linear sequence of phases. However, it has some limitations.

Limited flexibility for changes

The

structured approach of waterfall can make changes challenging once a phase is completed. This rigidity can lead to difficulties in adapting to new requirements, costly revisions if requirements change mid-project and can inhibit creativity and innovation during the development process.

What is ITIL? Waterfall methodology can result in longer delivery times due to the extensive upfront planning. This approach can lead to delays in delivering working software to end-users and slower time-to-market compared to more iterative approaches.

Simon Buehring Waterfall may present obstacles by restricting customer collaboration after the requirements phase. This can lead to limited stakeholder input and a potential mismatch between the final product and the evolving needs of the customer.
