Managementspeak is almost solely consistent of tired, overused phrases that are supposed to convince people of the speaker's point, without the speaker having to actually explain himself. There is simply no excuse for anyone, anywhere, to use the phrase "think outside the box" any more, because when people hear it they immediately get a bad reaction. I know when I hear that phrase, I wince and immediately lower my opinion of the person for trying to sound more intelligent than they really are.

George Orwell gave his six rules for writers in his brilliant essay, "Politics and the English Language". They are:

(i) Never use a metaphor, simile, or other figure of speech which you are used to seeing in print.

(ii) Never use a long word where a short one will do.

(iii) If it is possible to cut a word out, always cut it out.

(iv) Never use the passive where you can use the active.

(v) Never use a foreign phrase, a scientific word or a jargon word if you can think of an everyday English equivalent.

(vi) Break any of these rules sooner than say anything outright barbarous.

Conrad is right when he says that managementspeak is like Mandarin, but the best managers will totally avoid such silly, useless, self-important speech. I would add that Orwell's rules should also be applied to speaking.
