Agile Vs Waterfall: Which is a Better Model of Development?
Waterfall Model methodology is also known as Liner Sequence Life Cycle Model. Waterfall Model followed in the sequential order, and so the project development team only moves to the next phase of development or testing if the previous step prepared and obtained successfully. Whereas Agile methodology is a practice that helps continuous phase of development and testing in the software development process. In this model, development and testing activities are contemporary, unlike the Waterfall model. This process allows for more communication between customers, developers, managers, and testers.
Advantages of the Waterfall Model
- It is one the easiest model of development. Because of its nature, each phase has a specific deliverable and a survey process.
- It works well for smaller size projects where the client’s requirements are less.
- Faster delivery of the project in the model
- Easily adaptable method for shifting teams
- This project management procedure is beneficial to manage dependencies on all levels.
Advantages of the Agile Model
- It is a focused consumer process. So, it makes sure that the client is continuously involved during every stage, their feedback is a constant necessity.
- Agile teams are exceptionally motivated and self-organized so it likely to provide a better result.
- Agile software development method assures that integrity of the development is maintained
- The process is completely based on total progress. Therefore, the client and team know exactly what is exact and what is not.
Limitations of the Waterfall Model
- It is not an ideal model for a massive size project
- If the requirement is not clear at the beginning, it is a less beneficial method.
- Very difficult to move back to makes changes in the prior phases.
- The testing process starts once development is over. Hence, it has high bugs to be found later in development where they are valuable to fix.
Limitations of the Agile Model
- It is not a valid method for small development projects.
- It requires an expert to make crucial decisions in the meeting.
- The cost of enforcing an agile method is a little more compared to other development models.
- The project can easily go off track if the project manager is not clear what consequence he/she wants.
Conclusion
Both the models have their separate pros and cons, it’s up to you to decide which one has better functioning depending on your requirements and needs.
