Blacksheep a fine story of our times. Let me guess what happened next: The maintenance department told the middle management what had happened. The middle management did not tell the senior management the same story. Consequently, no lesson was learned.
Unless, of course, the maintenance department decided to start ordering key items of stock as before - despite the order to the contrary. This means that the system continued to operate normally, with the exception that some idiot in so called 'management' thinks they did a good job and received words and/or money to reward them.
Please tell me that I am just too world weary and cynical, that the company learnt the lesson and that the accountants were told to keep their nose out of things?
