This document discusses effective techniques for slicing stories into smaller pieces to improve agile workflow. It recommends slicing stories by acceptance criteria, user scenarios, workflow steps, and other factors. The "Hamburger Method" is described as a way to identify tasks within a story and slice it into smaller pieces or "bites" based on options, quality of solutions, and conversations with stakeholders. Slicing stories creates flexibility and allows teams to focus on early delivery of high value functionality.

- 3. Here’s why
- 4. Slicing creates options and exposes goals from solutions
- 5. Why should we make explicit slicing policies? ● ● ● ● Better definition of “ready” and “done” Measure cycle times for work types We can inspect and adapt policies Try and reduce instance of outliers
- 6. Shared definitions of work types are important “Theme” User registration “Feature” Forgotten password “Story” Email user
- 7. Slice by Acceptance Criteria ● Given Bob is a registered user, When Bob logs in Then he should be logged in. ● Given Bob is logged in, When Bob chooses Profile Then he should see his profile.
- 8. Each user scenario is its own story
- 9. Keep vertically slicing (user end-to-end functionality)
- 10. Workflow steps
- 11. Variation in business rules
- 15. CRUD operations
- 16. Test scenarios
- 17. Roles/personas
- 18. Other ways to slice ● ● ● ● ● ● “Implement the 1st X, then the rest” Delay performance considerations Delay UI considerations Look for “and”, “or” in scenarios Browser compatibility Usability
- 19. Hamburger Method
- 20. Step 1 - Identify tasks ● Story: Contact dormant customers by email ● Accomplishing all tasks would meet goal of story Lettuce V e r t i c a l s l i c e Tomato Burger Onions Tomato sauce
- 21. Step 2 - Identify options
- 22. Step 3 - Trim the burger options
- 23. Trimmed, ready for 1st bite
- 24. Step 4 - Take the 1st bite
- 25. Each bite is a story the PO may or may not want done ● ● ● ● Keep taking a bite until “good enough” Iterative = Be open to rework Horizontal slices don’t deliver value Conversations with the PO are key ○ Communicate technical risk ○ Focus on early value delivery
- 26. Group Activity Make your own burger! ● Story: I want customers to be able to buy my artwork from my website ● Use the Hamburger Method to slice this story ● You have 15 mins to: ○ Identify 5 or 6 tasks/stories ○ Identify options for each in order of quality
