Once you've seen enough buzzwords come and go, they don't affect you any more.
But take the scorecard example. Someone might say they want a "scorecard". Buzzword? Maybe. I know what they are trying to do, though. They want to have a way of monitoring how the company is doing that is easy to understand. That's to be expected of managers. They are supposed to know how things are going.
Not long ago, they would do that by looking through long, dry, printed reports full of numbers, making up a complicated spreadsheet, keying in many of the numbers from the reports, generating a graph, and interpreting the results while hoping they didn't make any data entry errors that would invalidate the results. The scorecard saves them lots of time. It's useful. It should help the company perform better. So I don't write it off as corporate doublespeak. It's just a word that communicates what they are talking about.
To me that's very different from blather like saying they are implementing a "Productivity Transformation Program" when they mean "We're laying people off". [that's real - from Schering-Plough] Or, "BHAG" which was popular for a while some years back. It was an acronym for "Big hairy audacious goal". The idea was that you should establish a very challenging target for something (productivity, sales, whatever) you want to achieve in 10 years. But somehow it was supposed to be more exciting to call it a "BHAG" (pronounced bee-hag).
