This will depend on MANY things:

• how much training (and what kind) you provide before (and after) Go Live
• the existing level of digital literacy your users have
• how you communicate before and during the Go Live
  
• how much you empower "champions" and "power users" to help your team
• the organizational culture when it comes to change
• how much existing processes were modified
• mechanisms you have in place to obtain (and promote) feedback
• any history of failed digital transformations
• how rigorous your systems are for logging and providing support (first come first served, prioritization, requiring tickets, hyper care, etc)
• how critical the work is that the organization does (ie: room for error and delays)
• the availability of self-help resources, work instructions, sop's, trained coaches, etc.

I can share for one of our current projects some metrics related to the ticket volume after a November 1st 2023 Go Live.
