This paper describes the psychological type, as measured by the Myers-Briggs Type indicator, (MBTI) of a representative sample of more than 4, 617 students who attended the Defense Systems Management College (DSMC) since 1985. This study addresses the contributions and potential pitfalls that personnel with each Myers-Briggs Type bring to an organization, and implications for leaders who must work in a possibly changing work force. this descriptive analysis may enable all who work in the defense acquisition environment to understand their coworkers better and, in this understanding, to enhance the overall acquisition process.
