The first major dimension on which competency modeling and job analysis differ concerns the completeness of the resulting picture of a job. As mentioned previously, the primary purpose of competency modeling is to identify those charac- teristics that differentiate superior from average performers(Spencer& Spencer, 1993); thus, itfocuses on attributes rather than activities, where job analysis may focus on either or both. More crucially, when job analysis focuses on attributes. the goal is commonly to present a complete picture of job requirements.
