You are only checking up and advising, not hovering or taking back. Be sure to follow up on these dates. Secure their commitment and assure them of your faith in their ability to do the job. Don't assume they know you think they can do it, tell them. This might be the toughest thing you will have to do.
People approach projects differently.
Since you have been clear with your expectations and established follow up dates, you should be free from disaster. Let them do it their way. Once the job is complete, praise people. Let them know how much they helped you and how much you appreciate their work. This is one of the best tools in a supervisor's arsenal.
