Autopilot sounds great, but easier said than done. Create a system (s) that eliminates interruptions, enabling me and my entire organization to be exponentially more productive? Sounds like some sort of pipe dream – the stuff of high-sounding books . . . or blog posts.
Perhaps we should start here:
Just because I am the leader, does not mean that I am not the smartest person in my organization. Others are just as, and possibly more capable of making decisions than I am.
With this understanding, start addressing each situation. Each time you are called upon to make a decision, consider if the person asking could have made that decision on their own. Start asking them what they would advise, or "what would you do?" type of questions, to encourage critical thinking and build your comfort and trust in their abilities.
Then, extend the authority.
"From this point forward, you do not need to call me for decisions related to . . ."
"I trust you ability to make the right decision in these situations."
Repeat as often as required until you have opened up your time to lead more effectively; to think, coach, challenge, train, influence and inspire. Your people and your organization will thank you. So will your family.
