“Management gurus agree to distinguish four levels of decision making for businesses. Strategic decisions define the relationships between the company and its environment (choice of activities, markets, technology clusters, …), they set axes and policies for the long term. Organic decisions define the organizational structures, processes, information systems (business, mission, delegation, responsibility, resources, …), they set the framework for the medium term. Management decisions for the short term set the direction and expected performance (objectives, resources, control, …). Finally, operational decisions are interested in the daily operation, in supervision of the execution.” Michel Bruley ( 2013 )
