The document discusses specification workshops, which are used to develop concise acceptance tests from user stories. It recommends using real-world examples as the basis for specifications and tests in order to develop a shared understanding between customers and developers. Examples should be specific, measurable, achievable, relevant and time-bound. The workshops aim to flush out additional test cases and reach agreement before development starts. Tips include focusing on building a shared understanding, using precise examples, and getting customers involved.
Specification workshops
- 1. Specification Workshops Getting the specs out of user stories Inspired by Gojko Adzic Kishen Simbhoedatpanday E: ksimbhoedatpanday@xebia.com T: KishenPanday
- 2. Do we really understand User Stories?
- 3. B-2 Stealth bomber Crashed – Loss of $1.4 billion “The aircraft actually performed as it was designed. In other words, all the systems were functioning normally.” “The human factor of communicating critical information was a contributing factor to this mishap."
- 4. Chinese Whispers Game 1) One person to think up a phrase. 2) Whispers it to the player who is next, and that player should make as much effort as possible to hear that phrase. 3) Next player whisper what they think was said to the next player, and so on, 4) Last player shouts out the phrase so that everybody can hear.
- 6. Are obvious things really obvious? How many points does the start have?
- 8. Specification Workshop Sprint Sprint Review Planning Development Specification Workshop to the Rescue Agile Acceptance Testing
- 9. Communicate examples Examples Requirements verify Tests
- 10. Agile Acceptance Testing 1. Use real-world examples 2. Select set of examples as specification & acceptance test suite 3. Automate verification of acceptance tests 4. Focus software development on acceptance tests 5. Use acceptance tests to facilitate discussion about future change requests
- 11. Automate on different levels UI Integration Unit
- 12. Keep workshop focused Here’s what I think we face Here’s what I think we should do Here’s why Here’s what we should keep our eye on Now talk to me
- 13. Tips during Specification Workshops Building shared understanding of the domain Point out different examples Brush off vague examples, be precise Flush out additional cases before development starts
- 14. Tips during Specification Workshops Other participants have understood correctly Workshops ends only when everyone involved agrees Build single project jargon Get customers on board!
- 15. Good acceptance tests have these properties Specific: explicitly defined Measurable: observable Achievable: realistic scenario Relevant: related to user story Time-bound: observed instantly
- 16. Building & Maintaining Shared understanding Being Agile Being stiff Individuals and interactions Processes and tools Working software Comprehensive Doc. Customer collaboration Contract negotiation Responding to change Following a plan
- 17. More about Collaborative requirements & Specifications
- 18. What would you rather be? Ferryman Bridge builder
