From Vilker's issue:

We’ve noticed that it’s possible for job coordinators to change the status of workflow steps to finished even if it’s not their turn yet.

We have one example (where the reviewer is assigned the QA step, so the agency can check the changed in the “review” step):
Translate (jobcoordinator): finished
QA (editor): open
Review (jobcoordinator): waiting → jobcoordinator changes it to finished and the whole workflow finishes.

While it certainly is a mistake on the agency’s side to manually change their jobs from waiting to finished when preceding workflow steps have not been completed yet, do you think it makes sense to (technically) disallow this?
Or do jobcoordinators simply need to be familiar enough with the system to not do this?

Solution

Restrict JC on his attempt to update job's state.

Check for state of task and step of JC job to determine what is allowed for JC
