What is Agile Adoption ?

Before we get into what is Agile Adoption, let’s try to understand what is ‘Agile’.

In software development, it’s an umbrella term for a set of frameworks and practices based on the values and principles expressed in the Manifesto for Agile Software Development .

Software development lifecycle(SDLC) is the step by step process followed in the development of software applications. It defines the various stages/phases involved in developing and deploying software, from the initial concept to its eventual retirement/maintenance. Each step in the SDLC has specific goals and activities that need to be completed to ensure the successful development of software. Here are the commonly used models in the SDLC:

1. Waterfall Model

The Waterfall model is a linear and sequential approach. It consists of distinct phases such as requirements gathering, design, implementation, testing, deployment, and maintenance. Each phase is completed before moving on to the next, and it’s difficult to revisit previous stages once completed. 

2. Agile Model

Agile follows an incremental approach and encourages the team to work simultaneously on different phases of the project. It embraces continuous integration and continuous development where one complex project is divided into multiple iterative and incremental smaller projects. Agile is a flexible method which allows changes to be made in the project development requirements.

3. Spiral Model :The spiral development model is a risk-driven, iterative, and incremental model. It is a hybrid software development model that contains elements of both waterfall and agile. The spiral model is used to handle projects prone to unanticipated risks but customer interaction is less.

5. V-Model : V model is a type of SDLC model where process executes in a sequential manner in V-shape. It is also known as Verification and Validation model. It is based on the association of a testing phase for each corresponding development stage. Development of each step directly associated with the testing phase.

Waterfall and Agile being the most commonly practiced SDLC models, Let’s further break it down. Waterfall model gained its popularity with the well structured sequence of phases where one phase is build upon the previous one. The Waterfall method’s appeal lies in its predictability and comprehensive planning. However, it has limitations. If any design flaw or requirement change occurs during development, it can cause delays and expensive modifications.

Example: Imagine a team of engineers and builders working together in the construction of a bridge, each responsible for a specific stage of the process. The project progresses linearly, just like the movements of a symphony, with each step building upon the previous one any modifications after the design phase will be just like trying to rewrite a symphony mid-performance.

This led to the emergence of a more flexible and adaptive approach: Agile methodology.

Agile’s popularity soared because it addressed the limitations of Waterfall. It thrived in an environment where change and unpredictability were common. Agile’s flexibility and iterative approach allowed teams to adapt to evolving requirements, incorporate user feedback, and deliver value faster. This dance-like methodology promoted collaboration, creativity, and customer satisfaction. Experienced professionals appreciate Agile for its ability to navigate complex projects, manage uncertainty, and foster innovation. Ultimately, Agile is a mindset evolved by following Agile Manifesto‚Äôs values and principles. Those values and principles provide guidance on how to create and respond to change and how to deal with uncertainty. There are multiple frameworks that follows this Agile mindset and projects can adopt any of these, or even go without a framework just by sticking onto the values and principles of Agile.

Conclusion : Just as a symphony and a dynamic dance captivate different audiences, the Waterfall method and Agile methodology offer distinct approaches to project development. Understanding their unique characteristics helps us appreciate the strengths and weaknesses of each and choose the most suitable approach for our specific projects.
