This first key to success is by far the most important one. Because site managers affect the results of their wash, it is worth the effort to create a Job Model for that position and evaluate internal or external candidates to see if their behavior traits match the requirements of the job. When someone is a match for any job they achieve more, are happier in their work, and are actually less influenced negatively by family and friends in terms of industry image. When the job satisfaction of a successful manager is high, the chances of retaining that person are better.
