SHELL-Team is based on modelling team performance and considers several interacting SHELL units (such as 3 cockpit crewmembers and an air traffic controller) where each unit shares certain components with other units according to the working environment/situation and task requirements (Cacciabue, 2004 1).
For example, a SHELL-T model might convey that each flight crew member has hardware to interact with, all crew members share the same environment and all crew members communicate with each other and the air traffic controller for performance of the flying task. However, the SHELL-T model may also suggest that the pilot and co-pilot share different software (procedures and training) to the software associated with the flight engineer (the third crew member). Similarly, the SHELL-T model may convey that the air traffic controller communicates with crew members but does not share any other elements of the SHELL-T unit (operates in a different working context, with different rules and regulations and with different control system hardware) (Cacciabue, 2004 1).
