Questions worth asking there

A claim at a show is a starting point. These questions help you test it.

  • What unit-level or patient-level outcome data support this claim, and over what period?
  • Was the result measured against a comparison group or only before and after?
  • Which care settings were studied, and how close are they to the one under discussion?
  • Who sponsored the evaluation, and is the full report available?

Plan it

Guides for any show

First time at a major show

A show floor rewards a plan. Decide what you need to learn before you see the program, then let the program fill the plan.

Show planning checklist

The same checklist works for a payments summit, a marketing conference and a machine tool show.

Parking and getting there

Parking and transit change by event and by day. The venue and the transit agency are the sources to trust, close to the date.

Hotels and travel

Use the organizer's official housing page as your starting point. Third-party offers that use a show's name are not always connected to the organizer.

During the show

A claim on a show floor sounds as firm as a published figure. It usually is not. Keep the same few questions in your pocket, and class what you hear.

Meeting planner

A meeting earns its time when both sides know the question before they sit down.

After the show

The value of a show is decided in the two weeks afterward, when notes turn into decisions or get lost.
