Toward providing guidance for procedure design: Formal definitions of procedure characteristics

A framework has been developed that is focused on providing guidance for the design of procedures and checklists. The framework identifies characteristics of the procedure and environment that could influence procedure following behavior, and formal definitions of those factors are introduced. In addition, tradeoffs between the factors that can be controlled by procedure designers are described. This framework, along with the formal definitions, should help enable provide more concrete guidance for researchers and practitioners concerning the design of procedures for human-machine systems.
