Deriving intentions from examples
Collecting examples and deriving intentions requires collaboration
between the „three amigos“

Formalizing scenarios (AC)
scenarios = abstract acceptance criteria illustrated with examples (AC)

Lessons learned
Track progress of scenarios accessible for all project stakeholders
•builds trust: know what’s going on
•shows what’s ready to test: completed, temporarily not working
•helps involving business into BDD cycle
30
Lessons learned Align tasks with scenarios task planning after formalization of scenarios
• helps team with task planning (some teams even drop task planning)
• helps team limiting WIP on scenario level (not just user story level)
• yields earlier testable user stories (partial finished, prioritized scenarios)
