ABSTRACT
In this chapter, we have identified the importance of operationalizing performance in human-machine systems (HMS), measuring HMS performance antecedents, considering the type of task when evaluating HMS in spaceflight, establishing reliability and validity of performance measures, and measuring HMS performance using multiple sources, tools, and techniques. While these five considerations for measuring performance have been introduced discretely, it is important to note that they have overlap. For instance, a previously validated measure may be inappropriate for a given context and should thus be reconsidered. As a result, choosing metrics must be based on several additional metric evaluation criteria.
