It is said that "What one likes, one will learn to do well." When assigning someone to a job, I think the basic rule should be to give the job to someone who wants to do it. Although the actual work is out of your hands, it should never be out of your mind. That is why the manager should ask for progress reports as needed and, if any problem arises, offer advice and instructions. This is the principal role of a manager. The attitude of the manager should be, "Leave it up to them, but do not abandon them to it." In other words, delegate responsibility for an assignment but do not leave employees entirely on their own.
