Product development life cycle in agile methodology.

1. SME meets with the customer to determine the product requirements and build user stories.
2. Project manager break the requirements into independent tasks and estimate the time to complete each task.
3. Programmers present the customer with the task list and with time estimates, and have them create a priority list of features.
4. The programming team assigns tasks to pairs of programmers based on their skill sets.
5. Each pair creates unit tests for their programming task using the application’s specification.
6. The pair works on their task with the goal of creating a code base that passes the unit tests.
7. Each pair fixes/retests their code until all unit tests are passed.
8. All pairs gather and integrate their code base every day.
9. The team releases a preproduction version of the application.
10. Customers run acceptance tests and either approve the application or create a report identifying the bugs/deficiencies.
11. Programmers release a version into production upon successful acceptance tests.
12. Programmers update time estimates based on latest experience.
