In regulated environments there are potential disadvantages to documenting the current adhoc process in all its glorious confusion -- we may be audited to see if how the group operates in practice adheres to the letter of the documented process. If the culture is particularly compliance-oriented, then perhaps we end up "I'm sorry, to comply with our documented process, we can't proceed to step 5 until after the IT guy has returned to work. Since he's still at work today we'd better pause until he clocks off then returns tomorrow".
Both groups fell into child-like glee when it was explained to them that SEI level 1 involves writing down your current process as it actually exists. Which meant they got to describe the dumb stuff they'd been putting up with for years, with various degrees of tongue-in-cheek humor, satire, and sarcasm.
- Send boss email
- wait 2 hours for reply
- bug boss about email
- find out IT Guy already left for the day
- Resume process in the morning
Things like that, and a good time was had by all.
