Agile and Waterfall Development: What is It and Which is Better?


There are many ways to develop software, two of the most prominent methods are Waterfall and Agile. You may have heard about these methods if you had approached any software development company before. But you may be wanting to understand these methods better, regarding what is actually agile and waterfall methods and difference between them. Let’s understand it better now.

Difference Between Agile and Waterfall

The waterfall method works on the principle of fixed cost and fixed scope of the project. Once a step has been completed (design, development, testing, or any), developers can’t go back to a previous step. If they want to make changes, they need to start from the beginning. This method is followed when the project idea is ready with an extensive plan in the beginning and it has to be completed within a fixed budget.

But in Agile method, the project is started with working on small modules. The work on these modules is done in weekly or monthly sprints, and project priorities are assessed and tests are run at the end of each sprint. With these sprints, the bugs can be discovered, and customer feedback can be incorporated into the design before working on the next module. This method is followed when the project idea is not very clear or perfectly planned and it may need changes as the project goes.

Advantages of Waterfall Methodology:

• With the waterfall methodology, the project can be completed within the intended budget
• Waterfall model works well for smaller projects where requirement is small
• Phases are processed and completed one at a time

Advantages of Agile Methodology:

• Agile methodology allows to make changes to the program. So it’s easier to add features, which will keep you up-to-date with the latest developments in your industry
• As the project priorities are evaluated at the end of each script, clients are able to give feedback. So with the implementation of feedback, they can get the desired product.
• Testing at the end of each sprint makes sure that the bugs are discovered and fixed in the development cycle. So there will be no or minimal errors at the end.

When You Should Follow Waterfall Methodology?

Waterfall Methodology
  • As told above, you can choose waterfall methodology when you have a clear picture of what the final product should be
  • When you don’t need to change the project idea such as product features and functionality once the project is geared up
  • When you want to complete the project within the intended budget

When You Should Follow Agile Methodology?

  • When you don’t have an exact picture of what the final product should look like
  • When you need to change the project idea such as product features and functionality as the project goes
  • If your industry is experiencing rapidly changing trends
