The MPFJ instrument is comprised of two forms. The Importance form of the MPJFI instrument helps assess the relative importance of 16 basic job functions for overall successful performance in a given higher-level position. The Ability form (sold separately) helps provide an assessment of the relative ability of the individual to perform the 16 job functions.

The Importance form may be useful in defining, classifying, and clarifying organizational structure, determining appropriate selection procedures, and job evaluation for higher-level management and professional positions. The Ability form provides self, peer, and supervisory assessments that may be used in an all-around assessment process, and also a procedure for identifying individual and group training needs. This form has an optional, simplified response format for ease and speed of administration.
