You MUST know everything that's going on with your company when you're building a startup. If there's a manufacturing process, no one should know it better than you. If there's software, no one should be better informed about the state of the software than you.
HOWEVER... You CANNOT, SHOULD NOT, WILL NOT be able to CONTROL all of those things. And you SHOULD NOT try. Do what you are good at, be the biggest champion of your product and your people, and let those who are great at their jobs do them well.
Happy Tuesday, you know-it-alls!
