As a Change Manager I have to weigh in here ( 
). You have probably heard of the acronym ADKAR (Awareness, Desire, Knowledge, Ability, Reinforcement) I’d say you have the Awareness in place but the Desire may be lacking. Not uncommon if there is no burning platform.
What is the benefit of them doing the training from their perspective?
Happy to chime in more if I can help.
I did this and showed everyone the three ways they could access the SharePoint site, Outlook, Teams, the web.
It seems to be going smoothly now that people are getting on board with it.
The benefit to them, which I’ve tried to explain, is that they will have access to the trainings from anywhere and will be able to go back and look at old trainings now if they want them.
I’ve also tried to explain that this is also for me in that it helps me keep the trainings updated and keeps multiple version from being out in the wild, so everyone is looking at the same thing, along with me not having to send out a new email with a new presentation to everyone when there is an update.
Since communication is a big issue in the department I’ve also tried to explain that I’m trying to have everything available for them to view, not edit, so they know what trainings are coming up.
I appreciate all the feedback I received on this topic and have taken steps on my end to improve the new process and really explain to everyone why it’s important to me that we do the trainings this way. This is a great community.
