How about ability to integrate Guides with (Azure Cognitive Services) Computer/Custom Vision to help verify proper Step completion. For instance, you could confirm/verify things such as:

* All screws/bolts have been fully screwed in place
* All connections have been made
* Parts are properly oriented
* Cables are properly run

If any failures are detected, the user could be alerted during step execution -- or perhaps after guide completion, the user is guided to address each step where problems have been detected.
