Hi Gray,
Thanks for contacting CTB, but I think you have discovered a hole in our information base. We did searches for cost benefit analysis within both our Table of Contents and Connecting With Others. Nada! The only result that was remotely relevant had to do with cost-benefit of direct mailing procedures. You may find information of limited relevance under Developing Strategic And Action Plans.
We have referred your question internally to staff and other advisors in hopes that they can be of some assistance. Thanks for helping us identify a topic that might need to be addressed more thoroughly here.
