In light of repeated prescriptions for theory-driven prediction of job perf
ormance (Guion & Gottier, 1965; Tett, Jackson, Rothstein, & Redden, 1999),
the complexity of the manager's role calls for a comprehensive performance
taxonomy more detailed than those offered previously. Review of recent disc
ussion of the fidelity-bandwidth tradeoff (e.g., Hogan & Roberts, 1996; One
s & Viswesvaran, 1996) and the need for greater articulation of job perform
ance (Campbell, 1994; Murphy & Shiarella, 1997) raise important issues rega
rding construct specificity in considering managerial behavior. None of 12
earlier managerial performance taxonomies (e.g., Borman & Brush, 1993; Torn
ow & Pinto, 1976; Yukl & Lepsinger, 1992) offers adequate specificity for m
eeting key research challenges. A "hyperdimensional" taxonomy of managerial
competencies, derived from the earlier models and developed using unique m
ethods, was subjected to content validation by expert review in 3 studies.
In the first 2, a total of 110 Academy of Management members sorted 141 beh
avioral elements into 47 competencies with average hit rates of 68% and 85%
, respectively. Results directed model refinements, including addition of 6
competencies. In Study 3, 118 subject matter experts sorted behaviors into
targeted competencies in a more rigorous task with an average hit rate of
88.5%. Findings support the model's content validity, its continued develop
ment, and most importantly, the pursuit of specificity in understanding and
predicting managerial behavior. The Scientific Mind-a mind nimble and vers
atile enough to catch the resemblances of things, which is the chief point,
and at the same time steady enough to fur and discern their subtle differe
nces; endowed by nature with the desire to seek, patience to doubt, fondnes
s to meditate, slowness to assert, readiness to reconsider, carefulness to
set in order, and neither affecting what is new nor admiring what is old an
d hating every kind of imposture.
