Agile

 

Agile model is a software development methodology that emphasizes the iterative and incremental delivery of software products. It is a highly adaptive and flexible approach to software development that allows for frequent changes to be made to the software product throughout the development process.

History:

Agile methodology was introduced in 2001 through the Agile Manifesto, a set of principles for software development that emphasized customer satisfaction, working software, and collaboration between development teams and customers. Since then, Agile has gained significant popularity in the software development industry.

Phases/Stages:

Agile methodology consists of several phases, including:

1. Planning: This phase involves defining the project requirements and creating a backlog of features that need to be developed.

2. Sprint: This phase involves developing and testing a small set of features within a short timeframe (usually 2-4 weeks).

3. Review: This phase involves reviewing the completed work to ensure that it meets the customer's requirements.

4. Retrospective: This phase involves analyzing the development process to identify areas for improvement.

Terminology used in Agile model:

Agile model uses various terminologies such as sprint, user story, backlog, daily stand-up, retrospective, etc. Agile model uses various technologies such as Continuous Integration (CI), Continuous Delivery (CD), and DevOps to support the iterative and incremental development process.

Some common terms used in Agile methodology include:

1. Backlog: A prioritized list of features or tasks to be completed.

2. Sprint: A fixed period of time (usually 2-4 weeks) during which a set of features or tasks are developed and tested.

3. Scrum Master: A team member who is responsible for facilitating the development process and ensuring that the team follows Agile principles.

Technology used in Agile model:

Agile methodology emphasizes the use of collaboration and communication tools such as online collaboration platforms, project management software, and issue tracking tools.

Frameworks of Agile model:

Agile model has several frameworks, including Scrum, Kanban, Lean, and Extreme Programming (XP), among others. Scrum is the most popular Agile framework that is widely used in software development.

Software application example of Agile model:

An example of the Agile model is the development of a mobile app. The development team would work in sprints to develop and test small sets of features, with each sprint resulting in a working version of the app. The customer would be involved throughout the development process, providing feedback and prioritizing features for development.

Industry acceptance of Agile model:

Agile methodology is widely accepted in the software development industry, with many companies adopting it as their primary software development methodology. Agile model gained wide acceptance in the software industry due to its emphasis on customer collaboration, frequent feedback, and continuous improvement. The Agile model provides a flexible and adaptive approach to software development that can help organizations respond to changing requirements and market conditions.

Market values of Agile model:

The market value of Agile methodology has grown significantly in recent years, as more organizations adopt Agile practices. The Agile Alliance reported that the Agile model has a market share of over 70% in the software development industry.

Advantages of Agile model:

1. Allows for frequent changes to be made to the software product throughout the development process.

2. Emphasizes collaboration between development teams and customers, ensuring that the final product meets the customer's requirements.

3. Results in higher quality software products due to the iterative and incremental approach to development.

Disadvantages of Agile model:

1. Can be difficult to implement in large organizations with multiple teams and stakeholders.

2. Requires significant communication and collaboration between team members.

3. May not be suitable for projects with strict deadlines or limited budgets.

In conclusion, the Agile model is a flexible software development methodology that emphasizes collaboration and iterative development. It has gained widespread acceptance in the software industry and is used in a wide range of projects across industries. While it has many advantages, it can also be challenging to adopt and may not be suitable for all projects.
