CSEL is exploring a new approach to testing and evaluation (T&E) of human-machine systems called joint activity testing (JAT). This methodology focuses on evaluating the performance of the joint human-machine system (i.e., joint activity) as challenge to the system increases. This methodology was designed to facilitate extrapolating insights outside the limits of discrete testing sets in order to better anticipate how complex human-machine systems will respond to scenarios that were not explicitly tested. CSEL has now begun to operationalize JAT in multiple healthcare and intelligence analysis domains spanning multiple projects and continues to further develop the methodology through these experiences.
