JOB FIT has traditionally been understood as depending upon ATTITUDES, MOTIVATION & VALUES and SKILLS, EDUCATION & EXPERIENCE. Today, we know that these elements rest on a foundation of COGNITIVE & INTERPERSONAL CAPABILITIES that really do not change with training, coaching or experience. Short athletes can love basketball; practice hard; and even have the skills, but success at a professional level is unlikely. Height is a critical factor for basketball. The best coaching and intensive training are not going to overcome a lack of height.  Similarly, some people can sell, and others cannot. Some handle details and planning easily, and others do not. Some learn quickly, and others take more time to learn the same thing. What are strengths in one job are weaknesses in another job. It makes sense to understand each individual's traits and abilities in order to understand and affect their job performance. Today that is possible with a simple online assessment that produces reports that anyone can understand.
