I recall having some great conversations with the Carson's.....Sullivan's.....et al about how a real activity should be structured....circa 1997-2001.

We still need the following in 2010:

An address/location/location type and link to directions on where a meeting is going to be held.

Many meetings have ContactS at them, need a list of attendees\roles.....

Sales Calls are often about a 'sub' Account....you call on Wal-Mart or Home Depot and talk specifically about a store opening that isn't the HQ Account.

You often bring product samples to a meeting (productID, quantity, lot # and expiration date).

Literature pieces......

Sub Activities (the check list of items to discuss that themselves may need follow up/another meeting/someone else's involvement)....

you get the idea.....
