The Agile method acquires the features of the iterative or incremental process model. More focus on process adaptability and customer satisfaction through the timely delivery of working software. The agile method split the project into small iterations, and these iterations do not directly involve long-term planning. The scope and requirements of the project are determined at the beginning of the development process. Plans about the number of iterations, the duration, and the scope of each iteration are already clearly defined. Each iteration is considered for a short period called a frame that typically lasts from one to four weeks. Each iteration consists of cross-functional teams working together in different areas such as:-
- Requirements Analysis
- Quality Assurance
At the end of the iteration, a working product is displayed to the customer and important stakeholders.
Working of Agile Model
The agile model believes that each project needs to be addressed differently to meet project requirements, and current methods should be changed. In Agile, tasks are divided into time boxes to provide specific features for the release.
In Agile, tasks are divided into time frames (shorter time frames) to deliver specific, to a variable. An iterative approach is taken, and the construction of the operating software is delivered after each iteration. Each build is incremental in terms of features; the final version contains all the features requested by the client.
The agile thinking process began early in software development and became popular over time because of its flexibility and adaptability.
Advantages of Agile Model
- This model encourages teamwork and cross-training.
- The functionality can be developed quickly.
- Less planning is required.
- Resource requirements are less.
Disadvantages of Agile Model
- Greater risk of stability, stability, and extensibility.
- There is too much individual dependency, as minimal documentation is generated.
