THEA - A Technique for Human Error Assessment Early in Design
Abstract
Human activity constitutes a major source of vulnerability to the integrity of interactive systems. Wherever human actions are either inappropriate, incorrect or erroneous there will be implications for design. This is especially true in high risk endeavors such as commercial air and marine transportation, power production medical care and space flight. The aim should therefore always be to design an interactive system as resilient to human erroneous actions as possible, and to achieve this as early as possible in the design phase. We present in this paper a formative error assessment technique contributing to the achievement of this goal, known as the Technique for Human Error Assessment (THEA). The method has been applied to several real- world case studies and has demonstrated its suitability in evaluating a design for its vulnerability to human interaction failures which may become problematic once the design becomes operational.
