How can I send a notification to users assigned a subtask, based on when the parent task is completed?

I have a type of task where each subtask can only be completed once the parent task is completed. I am looking for a way to automate sending a notification to those users assigned a subtask when the parent task is marked complete. Then, those users know they can begin working on their tasks. Any ideas on how to accomplish this?

Welcome, @Catie_Jaffe,

If you’re on any Asana paid plan, you can use Dependencies to make each subtask dependent on the parent task’s completion, then the assignee’s of the subtasks will receive a notification when unblocked.

(FWIW, This may be a bit confusing to some who would expect that seeing the parent task completed would mean that it’s subtasks must have already been completed.)

Hope that helps,
