The short answer is weak executive sponsorship. The longer answer is that we really aren't in a place right now where we can offer customers the value that a CAB demands. This was one of the key initiatives that executives wanted when we started our advocacy program, but when it came time to recruit, plan meetings, and action on feedback, we couldn't get the support we needed from the teams that needed to be involved. It became a very high-energy project with only marginal benefits.
