A career is the succession of positions held over the course of a professional life. It results from individual choices driven by the need for both professional and personal development. A career also reflects organizational management practices and, through the internal and external mobility it enables, serves as a key lever in job and skills management.

Finally, a career expresses social and normative rules that shape perceptions, guide behavior, and frame management practices. In this sense, a career is a multi-level concept—this is what makes it both rich and complex.
