> Sometimes this backfires badly: not only does everyone above them say yes, but someone somewhere up the chain loves the idea, and turns it into an "initiative" — i.e. something the line-level manager is now locked into doing.

I've seen a variant of this (repeatedly!) where a sales person will suggest the bronze/silver/gold/platinum edition of some product to a manager, the decision goes up the chain (unnecessarily), and then someone near the top says: "Platinum sounds the best!". Nobody dares take responsibility for suggesting "anything less than the best", so it gets locked in.

Meanwhile, the platinum edition exists only to make the silver and gold pricing look reasonable, so now... now... the consultant has to implement a solution based on the "bells & whistles edition" which takes 10x as long and has a bunch of issues. E.g.: "clustered" versus simply "active-passive" or weird nonstandard high bandwidth ports instead of ordinary Ethernet, etc.
