... Just as the Bureau of Labor statistics measure of overall national productivity (i.e., Gross National Product, GNP, divided by labor input) is of limited value, an overall measure of space station productivity is limit - .

... productivity from human performance in cognitive tasks until better measures of input resources, cognitive processes, and output measures are available. Productivity does, however, seem to be a viable metric to evaluate larger units of analysis of space-related missions in which the astronaut is considered one cc mponent of the unit of analysis.

... Improving Productivity Mast of the ra search issues presented in the Nick£rson paper dead mg with performance enhancements can relate to improving human productivity if the antecedent input quantities are evaluated in order to establish appropriate productivity indices. the unit of analysis at the human-machine interface level or above seems to provide the best cpportunities for improved productivity given the characteristics of the productivity metric.
