1. Agile Model :
Agile is a replacement for the traditional waterfall model for the creation of software development. It was developed in the year 2001 by a group of software developers for better ways for developing one. This mechanism divides the product into small builds and these small builds are developed with proper designing, coding, and testing with meetings until one build is completed. After this build, the other requirements are analyzed and the previous process is repeated until the final product is developed. The time for each build is called Sprints.
Advantages of Agile:
- It enhances collaboration among the teams.
- It promotes taking rapid feedback from the customer.
Disadvantages of Agile:
- It is not suitable for small projects.
- It requires a Scrum Master which may increase the cost of development.
2. Iterative Model :
The iterative model is a way of software development that works in small steps for the development of the software. It was developed by a group of software developers for better ways of developing one. It is an easy way to craft requirements into a software solution. This works in iterations as large tasks are divided into small steps and easy step is developed in iterations to achieve a final solution.
Advantages of Iterative:
- It makes easy debugging of errors.
- It is a more flexible way of creating software.
Disadvantages of Iterative:
- It requires good planning for deciding iterations.
- It needs well-defined modules to work on.
Differences between Agile and Iterative Model : S.No Agile Model Iterative Model
1. The Agile Model of software development is a type of model in which specifications and solutions enhance through the continuous collaboration of functional teams. The Iterative Model of software development is a type of model in which implementation starts with small elements, and iteratively evolves to the final solution through a collaboration of functional teams. 2. The process of development in this model is called Sprint. The process of development in this model is called an Iteration. 3. With the completion of a sprint, a meeting is carried out. With the completion of an iteration, a meeting is carried out. 4. Collaborating teams can review products during a Sprint. Collaborating teams can review products on the baseline of iteration. 5. There are two main roles in this model Scrum Master and Team member. There are two roles in this model Project Manager and Team Member. 6. Scrum Master is responsible for facility and team members do the estimation. The Project Manager is responsible for the estimation and completion of each iteration. 7. Test cases are prepared, identified, and executed by team members. Test cases are prepared, identified, and executed by Testers. 8. Deploying and Demonstration of software is done at end of each sprint. Deploying and Demonstration of software is done at end of an iteration.
