Stop switching gears every five minutes. It’s hard to get anything done, when you are asked to change directions five different times. Assign the work and let your people complete their tasks before giving them more work.
Stop micromanaging people. The biggest productivity blockers are leaders. There, I said what you are all thinking. If you trust someone enough to give them the job, trust them to do it without your over site.
Hire the best. Yes, it might cost a few dollars more to hire someone with additional skills or experience, but you can bet that most will be more productive on day one than newbies. When it comes to hiring talent. Hire the best and forget the rest.
