Abstract
In recent years there has been trend away from single sensor/single (SS/SI) indicator boards as the means by which overall understanding of current work-flow is expressed. Rather, computer screen based Supervisory Control And Data Acquisition (SCADA) systems are being modified to meet this need. This paper discusses a continuing experiment that compares existing SCADA design elements and those with simple display modification; display changes that facilitate decision making by improving overall Situation Awareness (SA).
