Build your team big enough so the burden does not become too great. Protect and invest in the people on your team. Don't let Bob spend 30 hours in one week volunteering to make a production happen while his family forgets who he is. Also, take an opportunity to invest in Bob. Get to know his family, take him to lunch just for fun.
Information is power.
Make sure you have a schedule planned out at least one month in advance. Fax the order of worship for the coming Sunday to the technicians no later than Wednesday or Thursday. This gives them time to prepare. Provide ample opportunity for your team to grow and learn. Subscribe to all the industry related magazines like TWM and MIX, and make them available to your team.
