But I’m concerned about tasks getting done on time

A lot of this comes down to communication and expectations, and when we start working on a task, yes, it may take you, let’s say 30 minutes to do a task, and it may take someone who’s never done it before, an hour. 

But once you show the person how to do it step by step, you’ll find that they’re completing the task within your time frame. 

If not faster sometimes.
