Advantages and Disadvantages of Agile Model when comparing it with Waterfall Model
Agile development model is also a type of Incremental model. Software is created in rapid, gradual cycles. As a result, small incremental releases are made, with each one building on the previous one’s functionality. To ensure that software quality is preserved, each release is thoroughly reviewed. It’s used in time-sensitive applications.
Advantages of Agile model:
- Customer satisfaction is achieved by the implementation of useful applications in a timely and consistent manner.
- Method and tools are less important than people and experiences. Customers, developers, and testers are continually in contact.
- Continuous attention to technical excellence and good design.
Disadvantages of Agile model:
- It can be difficult to estimate the effort needed at the start of the software development life cycle for certain software deliverables, especially large ones.
- If the customer representative is unclear about the desired result, the project may quickly become derailed.
The first Process Model to be adopted was the Waterfall Model. A linear-sequential life cycle model is another name for it. It is really easy to comprehend and use. In a waterfall model, each step must be completed before moving on to the next, and the phases do not overlap.
Advantages of Waterfall model:
- Simple and easy to understand and use.
- Because of the model’s rigidity, it’s simple to handle. There are unique deliverables and a review process for each step.
- For smaller projects with well-defined specifications, this method works well.
Disadvantages of Waterfall model:
- Until the end of the life cycle, no working software is made.
- High amounts of risk and uncertainty.
- Not ideal for projects with a moderate to high chance of change in specifications. As a result, this process model has a high level of risk and uncertainty.
