Are There Benchmarks to Compare Engagements?

Are there benchmarks to compare engagements to or should organizations compare with their engagements and effectiveness internally only? I think we have to be really careful about comparisons of different strategic environments. We wouldn't really want to compare the social media impression numbers to the time spent with a direct HCP engagement. The numbers tell us one story, but the direct impact of the one on one engagement is going to have more depth.
