What makes a good trade show lead?

At Exhibitor 2011, I was seated at a peer-to-peer round table, discussing everything from negotiating with organizers to how sore my feet were, when the subject of quality leads came up.

Someone asked, "what makes a good lead at a trade show?" Simple question., but not one with a simple answer. Unless you count "it depends" as a simple answer.

However, there are three important kinds of information you should get from whoever you define as a "good lead".

1. The contact info. This is typically the information scanned by the badge reader or carried on a business card. Important to know, if you want to reach your prospect after the show.
2. The content. Whatever you talked about relating to the prospect's needs for your products and services, scope & budget, and other stuff unique to your situation.
3. The action plan. Who's gonna do what and when after the show.

IMHO, you can't follow a lead from a trade show unless it has all three of these pieces.

Anybody have other critical stuff to add?
