What is Agile Methodology?
An agile methodology is an iterative approach to software development. Each iteration of agile methodology takes a short time interval of 1 to 4 weeks. The agile development process is aligned to deliver the changing business requirement. It distributes the software with faster and fewer changes.
The single-phase software development takes 6 to 18 months. In single-phase development, all the requirement gathering and risks management factors are predicted initially.
The agile software development process frequently takes the feedback of workable product. The workable product is delivered within 1 to 4 weeks of iteration.
Roles in Agile
There are two different roles in a Agile methodology. These are the Scrum Master and Product Owner.
1. Scrum Master
The Scrum Master is a team leader and facility provider who helps the team member to follow agile practices, so that the team member meets their commitments and customers requirements. The scrum master plays the following responsibilities:
2. Product Owner
The Product Owner is one who runs the product from a business perspective. The Product Owner plays the following responsibilities:
Every agile team contains self-sufficient team with 5 to 9 team members. The average experience of each member ranges from 6 to 10 years. The agile team contains 3 to 4 developers, 1 tester, 1 technical lead, 1 scrum master and 1 product owner.
The Scrum master and Product owner are considered as a part of Team Interface, on the other hand remaining members are the part of Technical Interface.
How an Agile Team plan their work?
An Agile methodology is not a specific set of ceremonies or specific development techniques. Rather, it is a group of methodologies that demonstrate a commitment to tight feedback cycles and continuous improvement. An Agile team works in iterations to deliver the customer requirement, and each iteration takes 10 to 15 days. However, the original Agile Manifesto didn't set the time period of two-week iterations or an ideal team size.
Each user requirement is a planned based and their backlog prioritization and size. The team decides, how much scope they have and how many hours available with each team to perform their planed task.
What is a user requirement?
The user requirement defines the requirements of the user in terms of functionalities. There may be of two type of functionality.
During software release planning, a rough estimate is given to a user requirement using relative scale points. During iteration planning, the requirement is broken down into tasks.
Relation between User requirement and Task
When the requirement is completed
The Agile team decides the meaning of task done. There may be different criteria for it:
What is Software Acceptance Criteria?
Acceptance Criteria is defined as the functionality, behavior, and performance required by a product owner. It defines what is to be done so that the developer knows when a user requirement is complete.
