This is, in effect, a capstone paper. We've studied some aspects of motivation. We've discussed personality. Finally, we've discussed job characteristics. Which of these, in your opinion, is the primary determinant of performance in most jobs? Support your decision with anecdotes drawn from your personal experience, the experiences of others, and (most important of all!) the material you read and studied throughout this course.
You should make use of at least six sources, suitably cited and referenced. These sources should include selections from the motivation, personality, and job design literatures.
