While I was converting my first firm from 2D to BIM, management allowed me to introduce an incentive program...
Once and employee had learned the software and felt comfortable, they got to take a competency test. If they passed they received a monetary prize as well a recognition diploma.
During employee reviews, part of their salary increase was influenced by a "competency grade" that was reported by the support staff or me.
BTW - as Tom wrote, you NEED complete management support for a successful implementation.
