Agile vs. Waterfall

Before the start of any software project, the team must choose a specific methodology that will be followed to complete the software development lifecycle (SDLC). This choice is between the Agile and the Waterfall methods.

Both methodologies can help developers produce high-quality project management. Depending on the specific project requirement, knowing the difference between agile and waterfall can better equip a development team to choose the right process and methods in delivering a successful software project. Some of the distinct differences are:

Waterfall vs Agile Methodology

• The Waterfall Method is a Liner Sequential Life Cycle Model while, Agile is an iterative method of development and testing, done concurrently, in the software development process.
• The Waterfall is a structured software development methodology, Agile is known for its flexibility.
• In the Waterfall methodology, testing comes only after the “Build” phase while testing is performed concurrently with software development in the Agile method.
• After the start of the project development process, the waterfall method does not allow any change in requirements while the agile method provides a scope of requirement change.

What is the Waterfall methodology?

The Waterfall Model methodology, also known as Liner Sequential Life Cycle Model, focuses on breaking the project into various phases and executing them in a sequential order where one moves to the next phase only when the previous phase is executed successfully.

Perks of Waterfall Methodology:

• The easiest model to manage as each phase has specific deliverables and a review process.
• Works well for smaller-size projects where requirements are easily understandable.
• Faster delivery of the project.
• Process and results are well documented.
• Easily adaptable method for shifting teams.
• Beneficial to managing dependencies.

Detriments of Waterfall Methodology:

• Not an ideal model for larger projects.
• Less effective when requirements are not described at the beginning.
• Very difficult to move back to make changes in the previous phases.
• The testing process starts once development is over. Hence, it has a high chance of bugs being found later in development where they are expensive to fix.

What is Agile methodology?

Agile methodology is the technique that helps concurrent iteration of development and testing in the complete process of software development. Hence, it increases the scope of improvement in every phase and enables better communication between customers, developers, managers, and testers.

Perks of Agile Methodology:

• Ensures that the client is continuously involved during every stage.
• Agile teams are extremely motivated and self-organized, so it is likely to provide a better result in the development projects.
• Assures that quality of the development is maintained
• The process is completely based on incremental progress. Therefore, the client and team are clear about the overall progress, reducing the risks during the process.

Detriments of Agile Methodology:

• Not a useful method for small development projects.
• It requires an expert to take important decisions in the meeting.
• The cost of implementing an agile method is a little more compared to other development methodologies.

Head-to-Head variations between Agile and Waterfall Model:

This was the first blog focusing on a better understanding of Agile and Waterfall Methodologies and the differences between them. This will help us to better decide the method that can yield better quality results.

We will be further discussing these methods in detail in our next blogs that will include:
