ABM is often seen as being "just another initiative" and often seen as "reorganising the deck chairs on the titanic" than a new way of working.

ABM isn't a new tool, it's a new way of working, your future state, has to be different from your "as is" otherwise it is just another re-organisation.

ABM is a change program, requiring input from sales, marketing, HR, operations, service and support.  It needs a new type of leadership and probably different skills from the people you have right now.  Good luck!
