PERFORMING ORGANIZATION NAME(S) AND AOORESS(ES)University Recent years have witnessed strong progress in understanding how people make decisions in operational settings.The emerging field of Naturalistic Decision Making (NDM) is at a point to afford system developers (including design engineers, human factors engineers, ergonomics specialists) different tools and methods for designing interfaces/systems that will better support decision making in those settings.Decision requirements can be identified from the early conceptual design phase through redesign.The NDM framework attempts to describe the way in which people handle difficult conditions within the context of the overall setting or task.This SOAR describes various decision strategies used by individuals and teams to assess a situation, diagnose a problem, and select a course of action.The impact of stress upon these strategies is also considered.To help understand what people are thinking as they perform difficult tasks, the procedures for conducting Cognitive Task Analyses to examine design requirements are also examined.
SUBJECT TERMS
PURPOSE:To describe the current state of knowledge about the way people make decisions in operational settings. This SOAR is written for system developers, including design engineers, human factors engineers, ergonomics specialists, and others who try to design systems, subsystems, and interfaces that will support better decision making.The problem addressed by this SOAR is that system developers usually aren't given details about how the people operating the system will use it to make difficult judgments and decisions. The SOAR explains how to obtain the decision requirements, and how to incorporate them into the design process. The SOAR also describes tools for identifying and using decision requirements. The SOAR is intended to show developers how to use decision requirements tools and methods to clarify system features and to design system interfaces that are easier to use at critical times. BOUNDS: This SOAR does NOT provide a detailed review of the decision-making literature of the past 35 years, since tha...
