Both Sides of the Coin

Abstract

Army analysts have developed an integrated technique for optimum system design early in the system development cycle called the Human Availability Technique (HAT). HAT combines a systems engineering technique, the System Capabilities Analysis Process (SCAP) with a Human Factors Engineering technique, Cognitive Building Block (CBB) Approach. Analysts implement HAT by creating human performance models that include both common Soldier functions from CBB and system capabilities from SCAP. To demonstrate the benefits of this approach for a complex system, analysts completed a proof-of-concept analysis with HAT for a conceptual 2-Soldier design utility vehicle. This case study demonstrated the benefits of including a detailed representation of both Soldier and system functions in one analysis.
