Edit automation rule

Edit the automation that assigns QA to cards moved to Ready for QA. Change the assignee from Sam to Elena, add a 24-hour due date from assignment, and update the comment to read QA assigned: Elena. Verify that existing cards already in Ready for QA are updated and notify Sam by DM that the change is complete.

Before I edit the QA assignment rule, make it easier for Sam, Elena and Product to accept the change: show how many cards are currently assigned to Sam and how many will switch, surface any downstream rules that fire on assignment (like notifications or checklist templates), and highlight which existing Ready for QA cards will inherit the new 24-hour due date so reviewers can decide if exceptions are needed.

I edited the Ready for QA rule to assign Elena and add a 24-hour due date, and now a handful of cards no longer show any due date. Product will ask why deadlines disappeared. I don’t know whether the rule overwrite cleared dates or if another rule removed them after assignment. What is the most likely cause and the immediate rollback or remediation I should run so I can report back confidently?

We’ve repeatedly edited live automation rules and introduced regressions that break SLAs and teamwork. Across several edits the common failures are unintended overwrites and missed communications to affected owners. What operational habit should we adopt: versioned rule edits with a dry-run on a staging board, a mandatory notification to assignees before changes, or approving edits in a weekly automation review? Recommend one change and how to pilot it this month.
