Have you run a (table-top) disaster response scenario at your company?

I've used it mainly for technical DR or incident response testing. For non-technical DR testing take a look at FEMA's tabletops as a starting point: https://www.fema.gov/emergency-planning-exercises. You can find a ton of free tabletops online

In my experience it's a useful pre-step to an actual DR simulation to shake out the low hanging fruit.

But, as you almost always find issues that you weren't aware of when you do the actual simulation, it's not hugely useful as an end in itself.

Essentially I see it as an insurance to make it more likely that you'll find useful things in the simulation.
