The 3 C’s of a Good User Story: • 1) The Card - The topic of the backlog item, the high level description of the desired system behavior. • 2) The Conversation - Detailed requirements are only discovered after the backlog item has been pulled into a sprint. This is a dialog between the product owner and the development team. • 3) The Confirmation - Criteria that insures the backlog item was completed to the specifications of the product owner. The customer will evaluate the competed backlog item against the acceptance criteria, and if all tests pass, approve the backlog item by the end of the sprint. www.synerzip.com
Business Priority MoSCoW Title - The title should be 10 words or less. H-M-L M-S-C-W Description- As a ________ I would like to ______________________________ so that ______________________________. XS - S- M - L - XL T-Shirt Size The Index Card - Overview: www.synerzip.com
Writing a Good User Story Description Template: • As a _________________________ I would like to __________________ so that ________________________________. • Example: As a (role or persona), I would like to (execute an activity), so that I can (see or achieve a value or benefit). www.synerzip.com
High Each Sprint implements The highest priority features Each new feature is Prioritized & added to the stack Features may be reprioritized At any time Features may be removed At any time Low Features Product Backlog Design: • All possible system features are captured in a stack rank ordered list called the product backlog. • New features can be added to the backlog at any time. • Features in the backlog have a gross estimate of effort and or value. www.synerzip.com
Breaking Down The Work: www.synerzip.com
What About Business Priority? • We all know the business has a 3 point ranking scale for priority of backlog items: High, Really High, or Really Really High. • The business needs to use tools to help them understand that not everything can be of the highest priority. • With the understanding that we would not be doing the work if it were not important, which items have the greatest urgency? Can we arrange them into High, Medium, and Low categories? Two websites to assist with priority:http://dotmocracy.orghttp://www.innovationgames.com www.synerzip.com
Time vs. Relative Complexity: • Let’s paint the room! • How many hours will it take? • Why all of the different answers? • Have any of you painted before? • Compared to something else you have painted, would it be easier to determine how difficult it would be to paint the room? • Is it easier to reach consensus? www.synerzip.com
Planning Poker - Does It Work? www.synerzip.com
Let’s Use a T-Shirt Size... • Smaller Than XS = a Task. • Extra Small = 1 • Small = 2 • Medium = 3 • Large = 5 • Extra Large = 8 • Larger than XL = an Epic www.synerzip.com
Understanding MoSCoW: • MoSCoW = more than a Russian Capital • Must Have • Should Have • Could Have • Would Like • Every iteration should have a mix of the above types of items. • Stake holders LOVE the Would Likes. • The Product Owner drives the product backlog and creates the rank order based heavily on the MoSCoW ratings. www.synerzip.com
Understanding Velocity: The rate at which a team can produce working software Measured in non-time-referent terms (e.g., Story Points) per Sprint More accurately stated, it is measured in terms of the stabilizednumber of Story Points a team can deliver per sprint of a given length, and with a given definition of Done. Used for estimation and planning Can be artificially increased by cutting corners on quality Must have stabilized to be reliable Should not be used as a measure of comparison across teams Lean concept of Limiting Work to Capacity www.synerzip.com
Velocity - An Example: Example: Team A is working in 2-week sprints on work that it has estimated together. Team A has been working together for several sprints, and consistently delivers between 18 and 23 points of working software every sprint. We could reasonably expect Team A to deliver roughly 20 points per 2-week sprint, and so we consider that to be the team’s velocity for planning purposes. If there are eight 2-week sprints in a release, we can extrapolate that Team A has the capability to deliver 160 points in a release. www.synerzip.com
Connecting The Dots: Size (complexity) is estimated A story is estimated to be 3 story points in relative complexity Velocity is measured “Team A can deliver 20 story points in a 3-week sprint” Duration is derived - “Based on Team A’s measured velocity of 20 story points per sprint, it will take Team A 3 sprints to deliver 60 story points.” www.synerzip.com
In Other Words... Backlog Item estimates answer the question “how big?”, rather than “how long?” Size estimates and observed Velocity, used together, are answer the question “how long?” www.synerzip.com
