Agile Methodology

Agile methodology is a project management approach that prioritizes flexibility and collaboration. It is based on the Agile Manifesto, a set of values and principles for software development that emphasizes individuals and interactions, working software, and customer collaboration.

In an Agile project, the requirements and solutions evolve through the collaborative effort of self-organizing and cross-functional teams. The project is divided into small phases of work, called sprints, which typically last two to four weeks. At the end of each sprint, the team demonstrates a working product increment to the customer. The customer can then provide feedback, which is incorporated into the next sprint.

One of the key principles of Agile methodology is to deliver working software frequently, with a preference for the shorter timescale. This allows the customer to see progress and provides the team with opportunities to gather feedback and make adjustments.

Scrum is one of the most popular Agile frameworks. It is a process framework that defines specific roles, events, and artifacts to help teams implement Agile methodology. The roles in a Scrum team include the Scrum Master, who is responsible for ensuring the team adheres to Scrum principles and removing any obstacles; the Product Owner, who represents the stakeholders and is responsible for the product backlog; and the Development Team, who are responsible for delivering the software.

The events in Scrum include Sprint Planning, Daily Scrum, Sprint Review, and Sprint Retrospective. Sprint Planning is a meeting where the team plans the work for the next sprint. The Daily Scrum is a short meeting where the team reviews progress and plans for the day. The Sprint Review is a meeting where the team demonstrates the working software and receives feedback. The Sprint Retrospective is a meeting where the team reflects on the past sprint and identifies ways to improve.

Artifacts in Scrum include the Product Backlog, Sprint Backlog, and Increment. The Product Backlog is a prioritized list of requirements for the product. The Sprint Backlog is a list of items from the Product Backlog that the team commits to delivering in the next sprint. The Increment is the sum of all the product backlog items completed in a sprint and the value of the increments of all previous sprints.

Another Agile Framework is Kanban which is a workflow management method that emphasizes visualizing the flow of work, limiting work in progress, measuring and making process policies explicit, implementing feedback loops, and improving collaboratively and evolving experimentally. Kanban boards typically have columns that represent the different stages of a workflow, and cards that represent tasks. The team pulls tasks from the "To Do" column into the "In Progress" column, and then moves them to the "Done" column when they are completed. By limiting the number of tasks in the "In Progress" column, the team can focus on completing work before starting new tasks.

In summary, Agile methodology is a flexible, collaborative approach to project management that prioritizes working software and customer collaboration. Scrum and Kanban are popular frameworks for implementing Agile methodology. They provide specific roles, events, and artifacts to help teams implement Agile principles and deliver working software frequently.
