FOR THOSE IN CHARGE: There are lots of things you don’t know and lots of people who hope you don’t find out. Beware of the naive confidence that because you have an open door that someone will tell you what you need to know.
Use your open door to exit your office, walk around with open eyes and ears. Talk to people. Ask questions. Not everything you learn will be what you expected. It’s your job to know what you need to know.
