In this paper we present a general model of organizational problem-solving in which organizations engage into an activity of cognition (un-derstanding the world in which they operate) and an activity of action (implementing those policies which cognition indicates as targets which better fit the world s characteristics). Both cognition and action are adaptively determined as the organization faces limitations in the cog-nitive capabilities of its members and in its control functions. Interde-pendencies among relevant dimensions of the environment and among basic operational tasks are only partly understood. The model allows us to study various combinations of decompositions of cognition and ac-tion and various stylized reward systems. In particular, we can address issues of centralization vs. decentralization of cognition, production and rewards schemes and the possible complementarities among these choices.
