Delegation for owners who can't let go
Most owners don't have a delegation problem. They have a trust and a training problem.
Delegate outcomes, not tasks
'Schedule the trucks for the week' delegates an outcome. 'Open the spreadsheet, click here, type this' delegates a task. Owners who only delegate tasks stay the bottleneck forever.
Accept B+ work
The person you delegate to will do it 80% as well as you would. That's the deal. If you keep redoing their work, they stop trying and you stay the only person who can do it.
The first three months are training, not delegation
Real delegation only starts after someone has shipped the work a dozen times. Before that you're teaching, not handing off.
