Manifesto for Agile Software Development

We are uncovering better ways of developingsoftware by doing it and helping others do it.Through this work we have come to value:

• Individuals and interactions over processes and tools• Working software over comprehensive

documentation• Customer collaboration over contract negotiation• Responding to change over following a plan

The goals of Agile

• Rapid product development• On time delivery• Excellent quality end products• Customer satisfaction• Team achievement• Cost effective product development• Quick adaption to business changes

What is Scrum Methodology

• Scrum has been a framework for developing and sustaining complex products since early 1990s.

• Developed and sustained by Ken Schwaber and Jeff Sutherland.

• We can address complex adaptive problems, while productively and creatively delivering products of the highest possible value.

• Scrum is: – Lightweight – Simple to understand – Extremely difficult to master

October 2010 9

Scrum Framework Preparation Phase

Create User Stories – Written from user perspective “As a sales clerk, I need to be able to enter a sales order”.

Step 1 – 1 day planning session• 2-4 hour release planning per release

– Team, Scrum master & product owner discuss project requirements – Assign story points to user story– Team prioritize user stories identified for the release and group them

into sprints• 2-4 hours sprint planning per sprint

– Poetize user stories selected for the sprint – Team defines detailed tasks for each story – Team selects tasks for each sprint – Team members assign tasks to themselves

04/13/2023 10

Scrum Framework Step 2 - Team works on the current sprint - 2 Weeks

• Daily 15 min. stand-up meeting – Team, Scrum Master, Product Owner– What has been completed – competed work per each day– What to do today – What prevents each member from completing one’s work

Step 3 - Sprint review at the end of each sprint - 1 to 2 hours • Provide a review session to discuss what has been completed with

team members, scrum master, product owner & steakholders• Decide what would be considered completed within the current sprint • Decide what needs to be moved into next sprint

04/13/2023 11

Scrum Framework Step 4 - Retrospective after Sprint review - 1 hour

• What worked• What needs to be different

Step 5 - Start on next sprint

** Do this iterative process to complete release

• Daily scrum meetings – Remember small accomplishments and small goals

• Organizational obstacles become visible quickly

Scrum Challenges

• BAS & QA take part in the project on an going basis and are really responsible for the outcome of the project.

• Scrum is empirical. – The team adapts to new situation – The team has to adapt the process itself.

• Every team is allowed to change the time of a meeting, however they are not allowed to skip a meeting whatsoever.
