Agile Vs Waterfall: Comparing the Top Two Software Development Methodologies

Agile Vs Waterfall Methodology
There are numerous ways of developing a software. The two most common methodologies are Waterfall and Agile. However, availability of more than one method to develop a project makes it difficult to choose.

What Is Waterfall Methodology?

Waterfall Methodology is a traditional and most frequently used method for developing a software. The waterfall methodology is a linear design process. Each phase in this model takes place in a sequence and gradually flows down through all the phases forming a waterfall layout.

What Is Agile Methodology?

Unlike Waterfall, Agile Methodology works on a sequential approach with the flexibility of changing the requirement as and when needed. Agile Methodology came into use as a solution to the problems faced while using the Waterfall Methodology. Let us compare these two software development methodologies and analyze which could be a better approach for your business.
  1. Initial Requirement Gathering:

The Waterfall Methodology is a sequential software development methodology which demands the initial requirements to be defined. Whereas Agile Methodology is flexible and compatible with changing requirements.

2. Project flow:

The Waterfall Methodology encourages initiation and completion of software development as a single project with predefined SDLC phases. On the other hand, Agile Methodology divides a single project into multiple phases focusing on improvement in every passing phase with the help of feedbacks from the users and the QA team.

3. Customer involvement:

The Waterfall Methodology does not encourage customer involvement at any phase. Whereas Agile Methodology believes in customer satisfaction and thus involves customers in every single phase of the development cycle.

4. Quality analysis:

The Waterfall Methodology tests and ensures the quality of the whole system after the fulfillment of the predetermined requirements. The final phase of the project completion is testing and quality analysis. Nevertheless, this increases the chances of having multiple errors and dysfunctional features. On the other hand, Agile Management engages in testing and quality analysis at each phase of the development cycle with the help of user and developer feedbacks This helps in minimizing errors in the final stage.

5. Project delivery:

The Waterfall Methodology has a separate testing phase after fulfilling the requirements of developing a software. This increases the chances of having multiple bugs. Resolving the issues at this stage could delay the project delivery. On the other hand, in Agile Methodology, the product is tested with each passing phase of SDLC so that the project can be delivered on time to the client. In addition, the client can take over the project at any stage of development without any issues.

One can choose the methodology for developing a project on the basis of resources available in the company as well as the requirements set for the project. For more information or professional assistance contact Bexcode services.
