The need for tools which aid the decider organize decisional latitude was identified in a study of task organization decisions in three different manufacturing workshops. Hierarchical mechanisms in the decisional process were identified at both an organizational and an individual level. The hierarchy was found to be associated with different levels of detail relating to time, resources and work. The model proposed is based on the notion of decision centers characterized by a specific type of decision associated with a particular level of detail in the factors relating to work, resources, and time. The decisional latitude or leeway in a lower center is thus governed by decisions made at the next higher level. In a given center attention must be paid to : (1) coherence with higher level decisions, i.e. remaining within imposed decisional limits; (2) feasibility and decisional durability by allowing enough decisional leeway to the lower center. The design of ergonomic computer aids can be reformulated as a problem in the presentation of latitudes in resources, time, and work loads designed to help the decider make coherent, feasible and durable decisions about task organization. A prototype is described which presents latitudes in work load and time in a graphical way to aid task organization in hybrid manufacturing industries.
