CERN IT Department CH-1211 Geneva 23 Switzerland t CF Background Have applied SCRUM methodology with Procurement team for 2 years Now using SCRUM with Monitoring team Disclaimer The next “slides” are a personal opinion. If you follow any suggestion on this deck and your project fails, it will be your responsibility. ITTF SCRUM - 2

CERN IT Department CH-1211 Geneva 23 Switzerland t CF If everybody liked yellow… What would happen to blue??? One solution rarely fits all ITTF SCRUM - 3

CERN IT Department CH-1211 Geneva 23 Switzerland t CF Scrum in a few words “Scrum is an iterative and incremental agile software development framework” It is a framework that relies on teamwork and empowers the team to find solutions ITTF SCRUM - 4

CERN IT Department CH-1211 Geneva 23 Switzerland t CF Do’s Follow the recommendations: create a Sprint, review the Sprint and feedback on the process before starting again. Every team member should get all updates of a given project. Use Jira for keeping Product backlog and, based on that, create new Sprints (use Agile Board). Have one Jira project per team-project. In the spirit of the framework, take time to plan so you can execute as a team. Keep the ceremonies focused, the ceremonies are well described, don’t waste time. ITTF SCRUM - 5 don’t forget to execute the Sprint!

CERN IT Department CH-1211 Geneva 23 Switzerland t CF Don’ts Planning+Executing is very different from Support (unplanned activities). At CERN, don’t use Jira for User Support, use SNOW. Don’t skip the review and feedback (retrospective) meetings. Don’t let large stories from the Backlog into the Sprint. Sprint Planning is also breaking large stories into smaller ones Don’t assign Sprint Stories to other people. Don’t forget to adjust the Sprint length (1week – 4week) ITTF SCRUM - 6
