Design Tutorial: Command and Control

In the previous tutorials we have considered work domains located at the endpoints of the continuum described in Chapter 6. In this tutorial we will explore issues in ecological interface design for work domains located in the middle of this continuum. These work domains are characterized by interaction that is driven, in equal amounts, by law-driven constraints on the one hand and by intent-driven constraints on the other (e.g., hospitals, of¤ces, and manufacturing plants; see Figure  6.3, in Chapter 6, and Rasmussen, Pejtersen, and Goodstein 1994).
