There is no typical day at work. There are regular scheduled meetings but at any stage of the day someone or a project hits a crisis point.
I learnt very quickly to get the days work out of my so I can deal with the crisis as they arise.
Management were an interesting part of the game. They either didn't wont to know or micromanaged. The best of them trusted their staff to do what they did and did it well.
The hardest part of change management is to guide people down a path without taking dangerous shortcuts. The most enjoyable part was seeing the 'lightbulb' moment when the reason for a structured process is that it makes life easier not harder.
