Several years ago, I had to attend a full day "culture training" session given by Senn Delaney (a division of Heidrick & Struggles) [1]. It was also a massive waste of time. Our company actually has a really great culture, and what I remember of the training amounted to a somewhat subtle attempt to indoctrinate employees to be more blindly obedient to management change initiatives. There was some other stuff, but I honestly can't recall anything else. Maybe some simplified Meyers-Briggs type thing.
The only time I've heard any of the concepts cited since the training push has been in the context of some mid-level executive type pushing an unpopular top-down change, and even then, they seem to be at the bottom of their rhetorical sack. My co-workers' reaction ranged from neutral to eye-rolling, and as far as I can tell, no one has explicitly employed the trained culture concepts and the whole experience has mostly been forgotten.
I have no idea how much the my employer paid for all this, but the cost must have been enormous (every employee had to attend a course that took between one and three whole work days, with no multitasking allowed).
