Realize you have a certain degree of inefficiency within your team, and the number is likely higher than you think. The larger the organization the more likely this is to be true. Create systems to minimize this.
Focus on the margins – It’s worthless to focus on what happened on the past. Learn from it, don’t let it happen again, but don’t let it impact future decisions. Beware of sunk costs and know the cost of one more.
Always focus on opportunity costs. What are the lowest value activities your team does? If that was outsourced or automated, what else could they focus on up the value chain?
Focus on 80/20. There are a few things you do that contribute the most. Punt everything else to others.
Always explain why. If you ask somebody to do something, be sure you tell them why. If you don’t, bad things can happen.
