Arguments for Constructively Simple Models

Abstract

This paper examines in detail reasons for using constructively simple models in management science interventions. Constructive simplicity is an objective concept describing the form and level of detail in a model. It is distinguished from the subjective concept of transparency, which relates to user-comprehension of a model. Usual arguments for constructive simplicity focus on model-building considerations such as model clarity, flexibility and convenience. Constructively simple models are also an efficient way of learning about decision situations. Client managers may prefer constructive simplicity not only as a convenient way of ensuring transparent models, but also for reasons related to motivation, time constraints, implementation and involvement of third parties. A principal conclusion is that constructive simplicity in modelling is a robust strategy for effective interventions.
