The exchange at the centre of adoption
Every CRM rollout is a trade. The team provides structured information about their work. In return they should receive something that makes the work easier: a call list that assembles itself, reminders that arrive on the right day, customer history available when the phone rings, quotations that do not have to be retyped.
When the trade is fair, adoption happens with very little management effort. When it is one-sided, no amount of training fixes it, because the problem is not that people do not understand the software. They understand it perfectly and have correctly concluded that it costs them time and gives them nothing.
