I have to include this preface: Sentences full of "business words" make me sad.
Value-Add: "Is this really a value-add feature?" Are you really that big of a value-minus idiot? Would it be so hard to just rearrange your sentence to ask: "Does this feature make the product better?"
Core Competencies: aka stuff I know how to do. E.g. A manager core competencies are non-value-add.
Emergent: This one bothers me because I think people use it as a replacement for the word emergency. "I'm out of the office, but if you have an emergent need, please call me at...". Why not just use the word emergency? Is that extra character to write, or that extra syllable to say really that taxing?
These are the 3 that I came up with right now... but I'm going to start writing down words that people use at work that annoy me.
