The Auditor General examined five departments, and some 28 are heavily involved in this business. I would suggest that if he had a broader scope, he would probably have found similar activities in the other departments and agencies as well.
To keep my answer brief, I think sharing best practices became one of the elements of the action plan. Through a number of different mechanisms, the Auditor General has acknowledged the good work that was done to do that. Certainly, a number of departments and agencies are now combining forces when they share joint recipients, to lessen the burden in that sense.
