Microspeak: here we go again...
issue
All-purpose term for practically anything relating to a product, from a particular characteristic or bug to a delicate diplomatic iniative. Used indiscriminately and often.
blocking issue
A barrier or problem that prevents a neat solution to an issue. Usually technical but can be any sort of potential roadblock.

A marvellous example of management non-speak... Issues are there to be addressed and re-addressed but solving them is more scary! Corporate life may well, after all, be the same everywhere; has Dilbert any views on this?
