Keep focusing on the people who drive value out of the solution and the others will eventually catch on (or not). It is through recognizing the success that the solution creates, that the others will participate. Even with that being said, there is a small fraction of your employee base that will never use a solution. Their reasons in many cases are valid. I would encourage you to try to understand why people don’t want to use the solution, but not put a lot of effort into trying to change their minds.
