Agile VS Waterfall: A Complete Comparison

With many project management software swarming the Internet, Agile and Waterfall methodologies are the most popular methods. However, they can be confusing at times and hence we try to straighten them up in detail.

Introduction

The Agile methodology is a project management tool in which the project team manages the project by dividing it into several stages. It involves constant collaboration with the stakeholders and non-stop improvement and iteration at every step.


The Waterfall methodology is a kind of model that breaks down project activities into systematic linear sequences; hence, it’s also called the linear-sequential life cycle model. In this methodology, the subsequent phases rely on the deliverables of the previous one and correspond to the specialization of tasks.

Agile VS Waterfall: Which one should you use?

Before adopting Agile or Waterfall, it is wise to consider factors such as:

  1. Project requirements and regulations. Does the project consist of precise regulatory requirements without any future changes? Yes: choose Waterfall. No: use Agile.
  2. Stringent organizational processes. Does the firm have strict project processes that one must follow them? Yes: use Waterfall. No: use Agile.
  3. Client participation in project progresses. Do clients require an update of the project process frequently? Yes: choose Agile. No: select Waterfall.
  4. Nature of the project. Is it an already existing product that requires some upgrading? Yes: use Waterfall. No: choose Agile.
  5. Time scope of the project. Is the project deadline set and cannot be altered in any situation? Is the period short? Yes: use Waterfall. No: use Agile.
  6. Budget of the project. Is it already drawn up and inflexible? Yes: use Waterfall. No: use Agile.

Now, is there a way that you can use these two development methodologies to work on a single project? Yes, and you can find out the answer in the Agile-Waterfall Hybrid example below.

They achieve this by:

  1. Gathering and filing all project requirements up first and foremost.
  2. Designing the project model.
  3. Going into the development phase of a software or product.
  4. Testing the product when the development is complete.
  5. Receiving feedback on what has been created up to this particular project stage.
  6. Making changes according to the feedback until a perfect output is realized.
  7. Deploying the product and getting the final outcome.
