ABSTRACT
<p>Macrocognitive work systems are complex adaptive systems designed to support near-continuous interdependencies among humans and intelligent machines to carry out joint cognitive work that includes functions such as sensemaking, replanning, mental projection to the future, and coordination. The effort to identify empirical laws and use them to construct a formal theory led the authors to the identification of fundamental trade-offs that place performance limits on all macrocognitive work systems. This article presents five trade-offs that define these limits. It also illustrates how empirical regularities about the performance of human work systems emerge from the trade-offs.</p>
