J. Wolfsberger,
The reframing offers the design team opportunities to re-examine the problem set throughout the effort. Attempting to get the best picture of the problem set early is important, but the reality is that in almost every case the design team is not going to get it all the way right at the beginning.

Reframing happens throughout the design effort and gives the team the chance to see what has changed in the environment. Simply studying the environment changes it, and if the organization introduces any energy into the environment or system then it definitely changes.

Reframing does give the design team the chance to consider measures of performance and measures of effectiveness during the process. We have had difficulty getting this realistically accomplished in our experiments, so it doesn't seem that we've fully tested the feedback loop.

I'll check out the DTIC search and see what it brings up. Thanks for the recommendation.

Dave
