This paper reports on a study into the Levels of Abstraction Hierarchy (LOAH). The original proposition for the LOAH was that it depicted the levels of system representation, working from functional purpose through to physical form to determine causes of a malfunction, or from physical form to functional purpose to determine purpose for system function. The LOAH has been widely used throughout human supervisory control research to explain individual behaviour, but most control rooms comprise teams. The research sought to determine if the LOAH could be used to describe human supervisory control teams. A series of interviews were conducted in an energy distribution company. The results favour the LOAH, but suggest that people in the team are predominately operating at different levels of system representation, depending upon their team role.
