A-Cadre: Advanced Family of Manikins for Workstation Design

Abstract

A-CADRE, an advanced cadre of 17 manikins, is delineated and shown to be valid for assuring population accommodation when applied to workstations. As with the earlier CADRE manikins (Bittner et al., 1986; 1987), a general four-stage procedure was followed in percentile description development, but with variations designed to assure greater reach accommodation within a tighter percentile boundary envelope. A-CADRE manikins were evaluated for process- and outcome-validity in the context of a redesign of a cockpit workstation using a diagnostic model (CAR-IV). A-CADRE's process utility was found both (1) virtually equivalent to a 400-member random sample and (2) slightly greater than the original CADRE. Outcome validity was virtually identical to the original CADRE, and “more than adequate for workstation design purposes.” A-CADRE can assure workstation population accommodation within a tighter percentile boundary.
