Difference between Agile and Waterfall
Agile and waterfall are two different processes or methods for executing projects or work tasks. Choosing the suitable method for your project depends on the particular project's preferences and nature. Some projects require a more iterative process, while other projects require a more consistent approach.
Waterfall
Waterfall model process is also known as the sequential linear life cycle model. The waterfall model is performed sequentially, so the project team will enter the subsequent development or testing phase only after completing the previous stage. Following the waterfall method is a more straightforward process that moves tasks through requirements definition, implementation design, work item implementation, implementation verification and quality assurance, and final functional maintenance.
Agile
Agile methodology is a practice of continuous iterative development and testing that facilitates software development. In this model, in contrast to the waterfall model, development and testing are carried out simultaneously. This process improves communication between customers, developers, managers, and testers. According to agile methods, your project will go through a series of cycles throughout the project life cycle. Design phase, review, feedback, and then approve the work item, either yes or no. If no, note and make any necessary changes, track and adjust pending tasks or priorities to reflect the newly acquired knowledge, and then move on to the next task or sprint. Following the waterfall process, the method is a more straightforward process that moves tasks through requirements definition, implementation design, work item implementation, implementation verification and quality assurance, and final functional maintenance.
| Agile | Waterfall | |
|---|---|---|
| Structure | Flexible | Structured software |
| Process | Incremental approach | Sequential design process |
| Efficiency | Complete many projects | Completes a single product |
| Focus/Orientation | Customers | Project |
| Stages | Phases | Sprints |
