Like Mark, I've done this before and switched between paper and funtioning prototype and even an animated PowerPoint which we revealed when we got to the point of a feature that wasn't implemented. I've also used the mix-fidelity approach relatively late in development when a major requirement was suddenly thrust on the product team. I found it quite useful to do a few practice runs internally to get the transition down and work on the instructions in the facilitator's script. If you are doing something remotely, you might consider using a PowerPoint (or another interactive tool) as a fill-in for the particular missing functionality.
There was a great paper by Desiree Sy, one of my colleagues at Autodesk (then of Alias) where video and paper prototypes were mixed with working features in a multi-modal prototype test. I'll see if I can get hold of a copy of the paper. Chauncey On Wed, Jul 9, 2008 at 4:07 PM, Mark Pawson <[EMAIL PROTECTED]> wrote: > I agree with Todd.
