That's the fine art of emgineering: One striking sentence, demonstrating foresight and irony with the same words.

Then congrats to your top management. At least, "training" is quite close to a useful purpose.
The top management I experienced (=survived) created situations like that for reasons like stupidity, ignorance, carelessness, to cover mistakes of their own, a change of mind for no special reason (or maybe, because the wife said something during breakfast), or to bring people under pressure for easier control, easier handling and/or easier salary negotiation.
