Abstract
AbstractMany high‐reliability organizations must deal with the problem of requisite cognitive variety in operators of interactively complex technological systems. The present study describes an organizational script strategy dealing with this problem, based on development of shared meta‐scripts sustained by continuous learning. Analysis of mission briefing and debriefing protocols in an armored brigade indicated that most task‐related interactions were based on script language (i.e., verbs and action phrases signifying particular meta‐scripts and relevant contingencies). These protocols suggest that script‐trained operators construe complex missions as interchangeable combinations of 15 meta‐scripts, reducing cognitive demands or requisite variety to manageable proportions. An ongoing learning process, maintained via repeated script‐based feedback during debriefings, further reduces cognitive demands by increasing available variety in operators. Implications for performance reliability in ordinary organizations are discussed. Copyright © 2003 John Wiley & Sons, Ltd.
