User feedback comes too late, reducing opportunities for early improvement.
Suitable For:
Waterfall is best suited for projects with stable, clearly defined requirements, such as government systems, financial software, manufacturing tools, and compliance-heavy projects. It also works well for teams that prefer a structured environment with predictable timelines.
3. Rapid Application Development (RAD) Methodology
The Rapid Application Development (RAD) model, introduced in 1991, is one of the earliest iterative frameworks and remains a cornerstone of modern fast-paced development. Its core focus is accelerating delivery while maintaining high quality. Instead of following a rigid, linear process, RAD relies on rapid prototyping and continuous customer feedback to refine the product.
RAD operates through four main phases:
- Requirements planning
- Prototyping
- Testing and refinement
- Implementation
In this model, developers quickly transform requirements into functional prototypes and review them with the customer through multiple iterations. Each cycle gathers valuable feedback, helping teams detect issues early and reduce overall product risk. RAD often incorporates automation, low-code tools, and reusable components to compress timelines without sacrificing performance.
Advantages:
- Constant customer involvement helps catch problems early and reduces project risks.
