Agile Model - SCRUM Process Overview

Lot of testers have interest to know about,
1. What is agile model?
2. What is the advantage of it over other models?


Agile - Simply we can say "On demand, more monitored and controlled testing"
Agile model have benefits like,
1. Easy adoption of requirement changes at any stage.
2. Piece of working product will be arrived very early in life cycle.
3. More monitoring on team so every team members will be in same path and goal.


SCRUM is one of a process of agile methodology. SCRUM involves below terms,
1. Sprint
2. Scrum master
3. User Stories
4. Work Items
5. Sprint Back Logs
6. Sprint retrospective item, etc.


Sprint - Sprint is nothing but the scrum period. i.e. The no of days for between each release like 30 days, 15 days. This is mainly based on customer requirement. If your every sprint consists 30 days, then every 30 days there will be a release. Sometimes release will not be there based on customer request.


Scrum Master - The person responsible to assign the tasks to team members and monitor the team.


User Stories - User Stories are the original requirements from customer. This may be "New functionality" or "Change Request".


Sprint Work Items - Work Items are the Task items created by Scrum Master with Estimated time for each User story. Normally scrum master will create task item for each user story and assign it to some team member with estimated time.


Sprint BackLog Item - Sprint back log items are the sub task items created by every team member for each assigned work item. Team member will create this sprint back log item for each assigned work item and he will set estimated time. This is used to track the daily effort done by team member and to update the status like how much hrs actually worked on this sprint back log item. Automatically this will affect the Work Item related to this Sprint back log item. So finally the User story will be finished by doing all the work items related to that user story.


Sprint Retrospective Item - Retrospective item will be created after sprint release. This should cover the answers for below 2 questions.
1. What went well?
2. What can be Improved?


Now, you should be aware of above terms. Let's see, how actually scrum will be followed in real time projects.
1. Customers will enter the User Stories in your ALM system like TFS, QC, etc.
2. Once received user stories, scrum master will arrange a meeting called Sprint Planning Meeting
3. In Sprint planning meeting, scrum master will discuss with team members like
    What are the user stories we can select for this sprint?,
    Which user story going to handle every team member?, etc.
4. After planning meeting, scrum master will create Sprint Work Items for each user story and assign them to team members. For ex. Login Module is the user story. For this story, scrum master will create work items like Development of Login Module, Testing of Login Module, Regression and Retesting of Login module, etc. and he/she will put the estimated time to finish each work item.
5. Now, team members will pick up their work item and create Sprint Back Log Items i.e. sub work items. For ex. Team member will create sprint back log items like UI development, functionality development, unit testing, etc for Development of Login module work item.
6. Daily team members will work on their tasks and update their actual worked hours (i.e. burning worked hours) against estimated hours in sprint back log items.
7. This will give progress status for every sprint back log item which in-turn update sprint work item's progress. Finally every one can able to know the progress status of each user story.
8. Daily 10 to 15 mins quick meeting will be arranged by scrum master to update daily status, showstoppers and any blockings to continue the planned tasks. Based on this, they will continue their progress. This is called Daliy Scrum Meeting
8. Once everything is OK and working fine and tested, then we will go for release.
9.After the release, scrum master will arrange a meeting called Sprint Retrospective Meeting. In this meeting, every will discuss about the 2 points mentioned above and will create retrospective items if any.
10. In future releases, team members will concentrate to cover the created retrospective items as part of sprint tasks.


Hope this will give you basic idea about the scrum process in agile model...
