QIt’s possible to transfer information effectively on written documents without much of human contact. Essential knowledge is lost in every handover and human interaction is needed to overcome it.
  15. 15. Scrum Workshop by Practical Agile is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License. The Product Owner • The person that represents the customer. • Should have business knowledge or at least have access to it. • Has almost no authority over the team in technical aspects. • Exceptions are non-functional constraints and requirements And the definition of Done.
  16. 16. Scrum Workshop by Practical Agile is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License. Role of the PO • Defines the features of the product • Defines release dates and content • Responsible for ROI. • Prioritizes feature according to value. • Can change features and priority 
 once every predefined interval. • Decides what will be worked on in each iteration • Accepts or rejects results.
  17. 17. Scrum Workshop by Practical Agile is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License. Concept Change • Traditionally throws content “over the fence”– no more! • Takes an active role throughout the development lifespan. • Needs to make decisions regarding ROI every sprint. • The single wringable neck.

  19. 19. Scrum Workshop by Practical Agile is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License. The Product Backlog
  20. 20. Scrum Workshop by Practical Agile is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License. The Product Backlog • List of features, Technology, issues. • Items should deliver value for customer. • Constantly prioritized & Estimated. • Anyone can contribute.
  21. 21. Scrum Workshop by Practical Agile is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License. The Product Backlog • Visible to all. • Derived from business plan, may be created together, with the customer. • Can be changed every sprint!!! • Customer is not “programmed” to think of everything in advance.

  24. 24. Scrum Workshop by Practical Agile is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License. The Product Backlog • Can be defined in any way that serves best the PO. • User stories are recommended for functional requirements. • Usually contains the fields: ID, area, description, value, estimate, test criteria. • Common other fields: dependency details, source of item. • Remember to “KISS” - Keep it simple, stupid sweetheart!
  25. 25. Scrum Workshop by Practical Agile is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License. User Stories • Are not use cases! • Describe requirements from the user’s POV • A defined format:
 As a …. I would like to…. [so that….] • Should not include too many details. • Modeled for discussion, to overcome the communication gap. • Guidelines for a good story are: Independent, Valuable, Properly sized, Testable.
  26. 26. Scrum Workshop by Practical Agile is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License. User Stories - Example • As a customer I want to be able to check my current balance. • As a manager I would like to be able to see the overall balance of the customers. • As a manager I would like to see trends in sales. • As a sales person I would like to have a report of past activity for specific customers. • As a customer I would like to reprint receipts of past purchases.

  28. 28. Scrum Workshop by Practical Agile is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License. QIt is possible to “collect” or even “know” all the requirements up- front Requirements evolve as customers and our knowledge increases – based on experience
  29. 29. Scrum Workshop by Practical Agile is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License. Backlog Items Size • The product backlog items (PBI) become more granular the higher they are in the backlog. • Usually the PBI starts as very big items (Epics) and are split into smaller sized items. • It is common that the PBIs for the next 2-3 sprints are split so that: • 3-5 PBIs fit within a single sprint.
  30. 30. Scrum Workshop by Practical Agile is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License. Splitting User Stories • Different scenarios • Stubbingmocking external dependencies • Splitting across the data model. 
 E.g Support only a subset of attributes • Splitting across operations
 E.g CRUD parts of a protocol
  31. 31. Scrum Workshop by Practical Agile is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License. Splitting User Stories • Splitting on results
 E.g Success and failure scenarios. • Splitting cross-cutting concerns
 E.g Logging Security. • Splitting functional & non-functional requirements

  33. 33. Scrum Workshop by Practical Agile is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License. Backlog Grooming • Also called backlog refactoring. • Done by the team and the PO. • The goal is to have the backlog ready for the sprint planning. • Grooming = Splitting, clarifying & estimating.
  34. 34. Scrum Workshop by Practical Agile is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License. Backlog Grooming • Usually grooming just enough for 2-3 sprints ahead. • Recommended to allocate ~5% of sprint time for this task. • NEVER allow the PO to reach a sprint planning meeting with a backlog not in good shape.

  38. 38. Scrum Workshop by Practical Agile is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License. Why Plan? • Reduce risk. • Reduce uncertainty. • Gather data to assist in decision making. • Provide external stake holders with data. • Establish expectation to measure progress against.
  39. 39. Scrum Workshop by Practical Agile is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License. Estimating
  40. 40. Scrum Workshop by Practical Agile is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License. –John Maynard Keynes “It’s better to be roughly right than precisely wrong.”

  44. 44. Scrum Workshop by Practical Agile is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License. Why Relative? • We are not good in measuring absolute values. • We are good in comparing things. • We have the basic math skills (or a calculator). • High accuracy has a high toll. • Estimates become commitments • Time is not persistent.
  45. 45. Scrum Workshop by Practical Agile is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License. Story Points • Name is derived from user stories. • They reflect the “bigness” of a user story. • How hard it is ?
 How risky it is ?
 How much of it there is ? • Relative values matters.
  46. 46. Scrum Workshop by Practical Agile is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License. Planning Poker 1. Each person gets a deck of cards (Fibonacci). 2. The item to be estimated is read to all. 3. Attendants ask clarifications for the item. 4. Each person selects a card and puts it on the table facing down. 5. When everyone is done, cards are exposed. 6. If the estimations do not match a short discussion is done – Highest & Lowest estimators speak first. -> Goto 4. 7. Handle next item. 12 3 5 8 132040

Release Planning • Given that: – the items for the release are estimated. – The velocity is known (or predicted) – We know the scope or deadline. • We can estimate one of the two: – how much can we do until the deadline. – How many sprints it will take to complete the content. • The more data we will have, the more accurate will be our estimate.

Scaling the PO Role • Easy when feature teams exists. • Instead of a PO have a PO team. • Each team member is an APO – Area product owner. • Area product owner focuses on one or more requirement areas. • Team decides together how the general prioritization of the back log is. • Each APO has the responsibility to support, follow and prioritize within his areas. • APOs report back to the team for adaptations. • Usually an APO deals with the same teams for a long period of time.
