Agile vs Waterfall are the two software development approaches that are frequently used to finish projects. Agile employs an iterative process that changes as the project progresses. Whereas Waterfall demands that specific conditions be met before moving on to the following stage. Depending on the kind of project, both of these project management techniques provide significant advantages. Agile enables teams to work together across stages simultaneously while Waterfall requires them to finish each phase before moving on to the next.


The amount of iteration and flexibility that each offers are the primary distinctions between Agile and Waterfall. Agile is far more flexible and lets teams change their plans as they go. As a result, this strategy promotes teamwork and can lower errors because adjustments can be made to address any problems that arise during the development process. Waterfall, on the other hand, adheres to a more rigid framework and finds it difficult to swiftly adapt to changing requirements. If the project scope changes dramatically, this strategy might not be as effective as it is for projects with established goals and needs.


What Is Agile Methodology?


Agile methodology is an iterative software development methodology that relies on collaborative efforts between team members. Teams using it are better able to respond rapidly to customer changes while working more efficiently together collaboratively. Its values are collaboration, customer feedback, flexibility, and continual improvement.


Agile encourages teams to break large projects down into manageable pieces, deliver working code rapidly, respond swiftly to customer feedback, and implement necessary modifications quickly. Agile also empowers teams with autonomy over their tasks without needing an intermediary project manager or lead.


Understanding Waterfall Methodology


Waterfall methodology is an iterative, linear approach to software development that has long been one of the most prevalent practices. Based on achieving distinct goals with each stage of development prior to moving onto another step in order for successful completion.
