The design of interfaces for complex systems typically focuses on the tasks that individual users
must accomplish during any kind of mission or operation. A common approach used for
designing complex systems is the CTA. It is a powerful tool for improving existing technologies,
but it is insufficient for futuristic environments, since it requires access to subject matter experts
and existing system implementations (Redding, 1989).
For this reason, Nehme et al. (2006) proposed the Hybrid CTA, an extension of the CTA method
which addresses the lack of subject matter experts and previous documentation or
implementation, issues inherent to futuristic unmanned vehicle systems.
The Hybrid CTA enables requirements generation from a representative scenario of a futuristic task domain and compensates for the lack of task experts by using decision ladders to replicate the thought processes of a potential operator. However, the existing Hybrid CTA method does not specifically generate requirements related to collaboration or teamwork in general.
