2 Overview Scrum 2

3 Scrum Framework What is it Scrum is an agile framework that allows us to focus on delivering the highest business value in the shortest time; It allows us to rapidly and repeatedly inspect actual working software every two to four weeks (Sprints); The business sets the priorities. Teams self-organize to determine the best way to deliver the highest priority features. In every sprint, anyone can see real working software and decide to release it as is or continue to enhance it for another sprint. 3

12 Roles Product Owner Works on and communicates a shared Vision for the product with the Team and other stakeholders Gathers requirements (generally with assistance from others inside and outside the Scrum Team) Manages and orders the Product Backlog Accepts the software at the end of each Sprint Manages the Release Plan Manages Stakeholders Manages the profitability of the product (ROI) 12

13 Helps the Team Members as facilitator, coach and servant leader to improve continuously Works with the Product Owner to perform this role Roles Scrum Master Removes impediments to the Team Members Keeps the process moving at all times Ensures stakeholders are integrated Socialises Scrum to the greater organisation 13

14 Estimates Product Backlog items (generally User Stories) Contracts with the Product Owner to produce increments of deployable software......and delivers them Roles Team Tracks own progress Self-organises within the frame of their contract with the Product Owner and the organisation s rules Note: The collection of Team Members is termed the Development Team, Delivery Team or just team (with lower-case t). This is in contrast to the Scrum Team, which comprises one Product Owner, one Scrum Master and three to nine Team Members. 14

15 Artifacts Product Backlog A prioritized list of functional and nonfunctional requirements and features to be developed with items of most business value and/or risk listed first. The product backlog items of highest priority are granular enough to be readily understood by the Scrum Team and developed into an increment within a sprint. Lower priority product backlog items are progressively less wellunderstood and granular. This list transcends any one release and is constantly emerging and changing. 15
