I worked some place that did something similar, if not this exact thing. We answered a 20 question quiz of "do you do x, or y? Very in-depth, of course.

It's not an "all or none" situation, but it's supposed to be used as a guideline about how to best interact with different people. Blue/green would prefer a steady, consistent approach. Red/yellow want things fast and aggressive, etc.

What actually happened was people preening about getting the "good colors" that had traits that the company liked, and then absolutely no change at all in the culture or how we treated people anyway, regardless of results.

It was a complete waste of time, but the execs got big wall sized color charts and pinned everyone's names to them, so I guess they enjoyed their made up work for a bit.
