During a discussion with my friend Stephen Levy, he distinguished between implementing software and adopting it. A legal department can relatively easily implement software for the use of the department (install it on a server and get it up and running), but it is a much more challenging to have the right people in the department use the software in the right way. The latter series of steps is adoption of the software and it implies that the software is used effectively and makes a positive difference for the legal department.
Virtually all licensed software is implemented – installed on one or more computers so that it can run. Only some software in legal departments is adopted (See my post of July 8, 2009: software with 12 metaposts.).
