Abstract
Methodology is a term that comes from method and in project we often choose different types of project such as construction to which process may finish the project earlier. In this essay I have contrasted many different methods of traditional waterfall. I have write a brief review of the advantages of the water and disadvantages as well as agile approach towards the project using methodology waterfall effect. When it is appropriate to use it for project towards the end or start how it effect the project at the end is all discussed below.

Advantages of the Waterfall Methodology
1. The waterfall methodology stresses meticulous record keeping. Having such records allows for the ability to improve upon the existing program in the future.
2. With the waterfall methodology, the client knows what to expect. They’ll have an idea of the size, cost, and timeline for the project. They’ll have a definite idea of what their program will do in the end.
3. In the case of employee turnover, waterfall’s strong documentation allows for minimal project impact. Disadvantages of the Waterfall Methodology
1. Once a step has been completed, developers can’t go back to a previous stage and make changes.
2. Waterfall methodology relies heavily on initial requirements. However, if these requirements are faulty in any manner, the project is doomed.
3. If a requirement error is found, or a change needs to be made, the project has to start from the beginning with all new code.
4. The whole product is only tested at the end. If bugs are written early, but discovered late, their existence may have affected how other code was written.
Additionally, the temptation to delay thorough testing is often very high, as these delays allow short-term wins of staying on-schedule.
5. The plan doesn’t take into account a client’s evolving needs. If the client realizes that they need more than they initially thought, and demand change, the project will come in late and impact budget.
Advantages of the Agile Methodology
1. The Agile methodology allows for changes to be made after the initial planning. Re-writes to the program, as the client decides to make changes, are expected.
2. Because the Agile methodology allows you to make changes, it’s easier to add features that will keep you up to date with the latest developments in your industry.
3. At the end of each sprint, project priorities are evaluated. This allows clients to add their feedback so that they ultimately get the product they desire.
4. The testing at the end of each sprint ensures that the bugs are caught and taken care of in the development cycle. They won’t be found at the end.
5. Because the products are tested so thoroughly with Agile, the product could be launched at the end of any cycle. As a result, it’s more likely to reach its launch date. Disadvantages of Agile Methodology
1. With a less successful project manager, the project can become a series of code sprints. If this happens, the project is likely to come in late and over budget.
2. As the initial project doesn’t have a definitive plan, the final product can be grossly different than what was initially intended.
When should you use waterfall methodology?
1. When there is a clear picture of what the final product should be.
2. When clients won’t have the ability to change the scope of the project once it has begun.
3. When definition, not speed, is key to success.
When should you use agile methodology?
1. When rapid production is more important than the quality of the product.
2. When clients will be able to chance the scope of the project.
3. When there isn’t a clear picture of what the final product should look like.
4. When you have skilled developers who are adaptable and able to think independently.
5. When the product is intended for an industry with rapidly changing standards.
