The immunization-registry team has no Definition of Done, so stories marked done fail System Demo and stall the ART. What should the Scrum Master/Team Coach coach?
Select an answer to reveal the explanation.
Short Explanation
If done means something different on every immunization story, System Demo is where the argument starts. Write the Definition of Done down. That is how quality stops being a surprise that stalls the train.
Full Explanation
An explicit Definition of Done makes quality visible and reduces downstream stalls when immunization-registry stories reach System Demo. Implicit or private definitions produce fake-done work that fails integration and blocks ART flow. A demo-repair sprint after every PI, or counting any merge as done, institutionalizes the gap. The Scrum Master/Team Coach should facilitate a shared DoD the team actually applies.
