J. R. Galbraith, "Organization Design: An Information Processing View" Interfaces, 4 (1974), 28-36 SummaryGalbraith believes that "the greater the uncertainty of the task, the greater the amount of information that must be processed between decision makers during the execution of the task to get a given level of performance". Firms can reduce uncertainty through better planning and coordination, often by rules, hierarchy, or goals.Galbraith states that "the critical limiting factor of an organizational form is the ability to handle the non-routine events that cannot be anticipated or planned for".When the "exceptions" become too prevalent, they overwhelm the hierarchys ability to process them. Variations in organization design arise from different strategies to increase planning ability and to reduce the number of exceptional events that management must resolve.Galbraith defines a continuity of organizational forms that firms utilize to reduce uncertainty:1. Creation of Slack Resources. These include extending delivery times, adding more money to the budget, and building inventory (all which have inherent costs). If a firm fails to actively create a higher level strategy to address uncertainty, this strategy will occur by default.2. Creation of Self-Contained Tasks. One strategy at this level is changing from functional to product groups.3. Investment in Vertical Integration Systems. Condensing the flow of information by building specialized languages and computer systems can help analysis and decision making.4. Creation of Lateral Relationships. Moving the decision making power down in the firm to where the information exists can reduce uncertainty at the decision level.There are various strategies of increasing complexity to achieve this:A. Direct contact between managers across groupsB. Liaison personnel between groups.C. Task ForcesD. TeamsE. Cross-group Managers (project managers, program managers, etc.)F. Linked Managers (with power over some cross-group resources)G. Matrix Organization
