Understanding Agile Agile is often seen as a “solution� to the drawbacks of the waterfall methodology. Rather than a sequential design process, the Agile methodology works on an incremental approach.
Developers begin with a basic project design, and then work on small units. The work on these units is done on a weekly or monthly basis, and at the end of each week or month, project priorities are assessed and tests are done. These units allow for errors to be found, and customer feedback to be combined into the design before the next unit is run.Â

Understanding Waterfall ď‚ž
Waterfall methodology is a sequential design process. This means that everything is done step by step. The eight steps- outset, initiation, breakdown, design, construction, testing, implementation, and maintenance have to be completed one after another. Once a step has been completed, developers can’t go back to a previous step without discarding the entire project and starting from the scratch.

Strengths of Waterfall Methodology
The waterfall methodology allows for the ability to progress upon the existing program in the future as it stresses careful record keeping. The clients will have knowledge of the size, cost, and timeline for the project. They will have a clear idea of what their program will do in the end and there’s no room for uncertainty. Its strong documentation allows for minimal project impacting the case of employee turnover.

Weaknesses of Waterfall Methodology
Developers can’t move back to a previous stage and make changes once a step has been completed. If initial requirements are faulty in any manner, the entire project is ruined as this methodology relies heavily on requirements. If a change is needed or a requirement error is found, the project has to be started from scratch with all new code.
