Abstract : The Mission Operabilty Assessment Technique (MOAT) is an evaluation methodology that measures the operability of a system or subsystem in terms of operator tasks performed during a mission. MOAT addresses the problem of how well an operator can use a system or subsystem to perform tasks within the mission context. Contrasted to evaluations using human engineering design criteria which present only pass or fail information, this technique provides information on the degree of system and/or subsystem success or failure. This report discusses how MOAT was developed, how MOAT can be used on existing or emerging systems, and how MOAT will be expanded in future development to include multicrew station evaluations. This report examines how the three underlying technologies have been integrated into one comprehensive methodology. Task analysis, scaling methodology, and multi-attribute utility theory are discussed in terms of MOAT development and application. Finally, the report discusses the importance of developing systems evaluation methodologies which provide decision makers with meaningful information necessary for effective decision making.
