Indeed, the first course that House taught at Bay Networks, and the one that he considers most important, was on decision making. Here are some class notes. If you're not going to do anything differently tomorrow by making a decision today, then don't make it today. That's not an excuse to procrastinate. Don't be afraid to argue.
Unresolved conflict is a killer.
That's why real leaders deal with conflict head-on. They take individual feelings seriously, but then they get beyond those feelings. One way to make progress on a tough decision is to agree on what the question is. Agree on the wording and write it down. Debate often stems from having different ideas about what's being decided.
