I have a senior colleague with a lot of insider knowledge. He has too much information to write down at one time so I make documentation as I come across issues that require his attention.
He's been at one of our satellite offices for a long time due to some projects he's assigned to, but he's the only person I can go to for certain things. Sometimes he responds to emails instantly and other times he never responds to me at all. When something is really critical I will call him, but I don't like doing that often for several reasons.
- He has a bit of an accent which makes it hard to understand what he says sometimes.
- I like a paper trail and email makes it easy to reference exactly what he said and when.
- Some technical information is just better served over email like file paths, console commands, etc.
I don't want to go to our shared boss because I hate being seen as "telling" on my colleague.
How can I get my colleague to answer my questions in a timely manner, with a paper trail?
