Do Only What Matters. Break big problem into small manageable chunks. Prioritize. Attack high priority chunks in parallel using multiple teams. Do only tasks that are absolutely needed. Keep in mind the MSP (Minimal Sellable Product) concept in mind.
Think Big, Do Small.
Take baby steps.
Attack big big problem one small piece at a time.
Measure, Measure, Measure. To manage a successful team, we must measure everything the team do, how effective your team is. This mean we must gather metrics, and we must do thing in a way that allow us to obtain this metrics.
Presidents typically say they want to be surrounded by strong-willed people who have the courage to disagree with them. Sometime strong direct disagreement can be a bad thing. Sometime we need to apply some thought into what we say. In general, I should try to speak what is on my mind. If the group does not seem to pick-up my idea / suggestion, or the meeting is expanding in multiple directions, I may just need to repeat myself a couple of times.
Keep it simple.
