Here's a link to an excellent whiteboarding session on HCP in combination with HDD-MS. It explains first of all how Sharepoint works (high-level) and what possible issues one can encouter. Next, the session explains how HCP and HDD-MS will tackle each and every one of these issues.
Already had a "test-run" of this whiteboarding and got very good feedback.
I recommend for presales to master this whiteboarding session and apply it at customers (instead of showing the movie and becoming the person who presses the PLAY button )
