What is Agile Methodology?
Agile project management and software development is an incremental and iterative method that seeks to provide a software product as rapidly and efficiently as feasible while minimizing difficulties. Additionally, it promotes flexibility, collaboration, and continuous improvement throughout the development process. Moreover, it encourages customer involvement and adaptability to changing requirements. In addition, Agile methodologies such as Scrum and Kanban emphasize frequent deliveries of working software and close collaboration between development teams and stakeholders. Furthermore, Agile approaches prioritize customer satisfaction and value delivery, allowing for early and frequent feedback to drive continuous enhancements. Additionally, Agile practices foster transparency, self-organization, and empowered teams to achieve optimal results. Moreover, Agile methodologies enable faster time-to-market, improved product quality, and increased customer satisfaction through incremental development and continuous iterations.
What is Waterfall Methodology?
A traditional System Development Life Cycle (SDLC) paradigm is the waterfall technique. In contrast to Agile methodologies, it adheres to a sequential, linear design process that is common in software development and IT projects. However, in contrast to Agile, the waterfall approach adheres to a rigid structure where the completion of each stage precedes moving on to the next.On the other hand, it goes through stages such as requirement gathering, feasibility study/analysis, design, coding, testing, installation, and maintenance. In comparison to Agile’s iterative nature, the waterfall method emphasizes completing one phase entirely before starting the next. Nevertheless, if the development process requires changes or revisions later on, this sequential approach can pose challenges.
Agile & Waterfall
| Agile | Waterfall |
| Testing is carried out in parallel with development. | Testing is usually completed at the end of the development process. |
| Agile is iterative and incremental. | It is a sequential design process in which design, development, testing, and other phases are completed one after the other. |
| It is a firm believer in continuous feedback and is open to adjustments in requirements. | Customer feedback is rarely gathered until the very end of a project, and revisions are generally discouraged. |
| Requirements can be gathered even late in development. | Requirements are gathered before starting the development in the Waterfall model. |
| In Agile, Project is divided into sprints. | In Waterfall, the project is divided into stages. |
| The project is driven by self-motivated and self-organizing teams. | The project is drive by the project manager as a central controlling authority |
| It enables us to work on a few modest active projects at the same time. | It enables us to finish a single project. |
