The assessment of human/computer performance: a case for connectivity

Abstract

Multiple logistics processing systems are evaluated using human productivity measures. Comparisons between these systems are made to determine which system produces: greater savings in task execution time; greater reduction in task errors; fewer task steps for task completion; and higher user satisfaction. Multiple assessment methods, including interviews, deterministic (task flow) analysis, and controlled field experimentation accompanied by statistical inferential testing, are used. Results indicate the superiority of the LOGDIS Intelligent Gateway Processing system with greater connectivity. The multiple evaluation methods yield convergent results, allowing greater confidence in the evaluation outcomes.<>
