A great idea for getting a task completed in the best manner possible is to tell the employee the results that you want and get out of their way.
If you have hired good employees, and empowered them to get the job done, then let them have their head.
Don't squelch them, their ideas, or their initiative.
Many times they will have better ideas about how to accomplish a task than you would have.
Their way might not have been how you would have done it, but so what?
