Agenda What is scrum? Roles in scrum Scrum artifacts Scrum meetings Advantages Q & A
What is Scrum? Scrum is an agile approach to software development. It is an iterative development. The project progresses in series of Sprints. There is no team lead. Teams are self-organizing. Scrum Master is a coach for the team.
Ham and Egg story A chicken and a pig decide to start a restaurant. Chicken says “Lets call it Ham and Eggs!" Pig replies “No Thanks, You’d only be involved where as I’d be committed!"
Roles in Scrum Committed (Pigs) Product Owner Scrum Master Team Member Involved (Chickens) Stakeholders (Users, Customers..) Managers
Roles in Scrum Product Owner Writes User stories. Creates product backlog. Prioritizes user stories. Scrum Master Is a team member and NOT a team lead. Makes sure Scrum team lives by the values and practices of Scrum. Facilitates Daily Standup and Sprint Review meetings. Team Responsible for delivering the product. Typically made of 5-7 people.
What is Sprint? Sprint is a time-boxed iteration, typically 2-4 weeks. Output is a shippable product (No matter how basic it is). A release typically consists of multiple sprints. Each Sprint starts with Sprint planning, having daily scrum meetings, ends with Sprint review followed by sprint retrospective.

Product backlog Managed by product owner. It is the list of all the features to be added to the product. Contains user stories ( a short description of customer requirements). User stories re-prioritized by product owner after each sprint.
Scrum Meetings Sprint Planning Daily Standup Sprint Review Sprint Retrospective Only pigs are allowed to speak, chicken are welcomed only to listen.
Sprint Planning Estimate the effort/Story points from the product backlog. Planning Game / Poker Each User story is divided into Engineering tasks Every team member gets a deck of cards with numbers representing story points. For each user story every one estimates and show the card with that number. Discuss the discrepancies and finalize the story points. Determine the Sprint goal. Plan for the user stories for next sprint. Out come is ‘Sprint Backlog’ (list of user stories to be completed). Tasks are signed up by team members (Not assigned).
Daily scrum meeting Not more than 15 mins. Standup No problem solving Same time and same location 3 Questions What did you do yesterday? What obstacles are in your way? What will you do today?
SPRINT review Team presents the product that has bee built during the sprint to management, customer and product owner. 3 Questions What was the Sprint goal? What was committed from Product backlog? What is completed? Product owner checks against DONE criteria. Executed from dev environment. Stake holders comment/criticize on the developed functionality Identify not completed and new functionality to be added to the product backlog
SPRINT Retrospective End of each sprint Product owner, Scrum master and team are involved. 3 Questions What went well (Continue doing this) What didn’t go well (Stop doing this) Improvement areas (Start doing this)
Burn down charts To track progress Sprint burn down chart Shows number of tasks left in the current sprint backlog. Updated daily by scrum master and uploaded to a shared location (sharepoint). Product burn down chart Shows number of requirements left. Requirements can be added/removed.
Team Velocity Team velocity = Number of story points burnt in a sprint. If a team of 4 members complete 3 user stories with story points 5,5,8 story points respectively. Team velocity = (5 + 5 + 8 ) / 4 = 4.5 user stories per person in a sprint
Advantages Increased productivity. Continuous development process improvement. Team Team gets focused. One common goal. More accountability and responsibility. Flat structure, No manager-sub ordinate relation. Team work, No individual failure/success. Stakeholders Higher visibility. Better evaluation.
