If you want to force certain tasks to be completed in a specific order, you could create a task-based workflow that when you close a specific task, then it will add the next. That way, the only tasks that are available are the ones that are actionable.

For example, we do laptop replacements in my company using service requests. An example task would be to re-image the laptop, but that can’t be done until the equipment has been received and checked in. So, we have a task for checking the equipment in. Once that is complete, then the workflow adds the task to re-image the laptop.

Here is an example of what we have:

Hope that helps.

If you dont have a 1 then 2 then 3 task sequence requirement as @BortFrenzy stated above, the tasks will be generated in the order they are listed in your workflow. I just created a feature request with my specific use case as well as the pain I faced on a SR that has 12 tasks where they wanted to add a 13th, but at the “third” position and how it was super painful and didnt need to be from the automator standpoint.

See below, if you like the idea toss it an upvote for all of our sanity :)
