Operator workload often is given little consideration early in the design of a new system. Here we describe a projective application of the Subjective Workload Assessment Technique that can be used to evaluate workload implications of technology options before they exist in hardware form. Features of the technique that probably impact its reliability and validity are discussed. Further, a comparison of projected and measured workload was made for a set of system technologies. The results indicate that the projective workload assessment technique may be able to provide a meaningful workload analysis early in system design.
