Distributed Problem Solving in Modular Systems: the Benefit of Temporary Coordination Neglect

Abstract

The rising division of labour in problem-solving work such as complex product development is fuelled by principles of modular design. But because complex systems are only near-decomposable, modular decompositions always contain interdependencies that cut across modules. Extant research suggests that these interdependencies may not be neglected, and that distributed problem solving must be coordinated across the modules. But is ‘more’ coordination in modular systems strictly preferable to ‘less’? Analysis of a simulation model points to a trade-off: although constant coordination efforts are most effective in the short term, temporary coordination neglect—repeated switches between module-level autonomy and coordinating intervention—can yield superior long-run performance. The paper characterizes the conditions under which such temporary coordination neglect can be beneficial and suggests that the level of coordination in distributed problem solving serves to balance two functions: ensuring that the modules fit together and inducing broader search for better module-level solutions.
