• When customer choose Flexible Model (where customer request are accepted).

what are the terms used in Agile?

Terms Used in Agile are as below:-

• Customer is a Stack Holder in Agile Model.

• BA (Business Analyst) is a Product Owner in Agile Model.

• BRS (Business Requirement Specification) is a Product Backlog in Agile Model.

There are Different Approaches which are used in Agile.

• Dynamic Systems Development Method (DSDM)

• Evolutionary Project Management (Evo)

• Feature Driven Development (FDD)

• Kanban

• Scaled Agile Framework (SAFe)

• Scrum

Kanban and Scrum are the mostly used Agile Approaches.

Kanban:

Does not require fixed iterations. Work moves through the development process as a continuous flow of activity. A key feature is to limit the amount of work underway at any one time (referred to as the work in progress limit or WIP). The team works only on a fixed number of items at any one time and work may begin on a new item only when it is required to maintain flow downstream and after the previous item has been completed.

Scrum:

A lightweight process management framework based on empirical process control. Work is performed in a series of fixed length iterations, called Sprints, which last one month or less. At the end of each sprint the team must produce working software of a high enough quality that it could potentially be shipped or otherwise delivered to a

customer.

What is Sprint?

Sprint means iteration short development cycles.

Duration of sprint is 1 week Minimum to 4 week Maximum.

Here we are Assuming the Sprint is of Two Weeks. So all meetings duration is mentioned for Two weeks Sprint.

What is the flow of Agile model?

A short understanding of whole Agile model or a flow of processes is given below.

• A stack holder came with project demands/Requirement to product owner.

• product owner understand the requirement and write it down in the product Backlog.

• Product owner takes estimation from Development team and Testing Team.

• Business Analyst (Product owner) create the User Stories and add it to backlog,During the sprint planning meeting entire team discuss about User Stories available in backlog and based upon business priority User Stories are moved from backlog to sprint.

Stack Holder ----> Product Owner --> Product backlog --> Estimation --> Sprint backlog --> User Stories .

Advantages of Agile Model are:-

• DSM(Daily Scrum Meeting)
  

• Sprint wise delivery

• Priority Wise delivery
  

• Except CR at any point of time and also fulfil these CR

Disadvantages of Agile Model are:-
