Organizations can be assumed as the result of historic needs found in a certain environment and in the evolutionary process of social systems, hence, their sustainability depends on the capacity of understanding their own complexities. This paper proposes that the provision of conditions for innovation, as an expression of organizational structure, is an option that ensures sustainability and requires a non-uniform non-predictable process, meaning by this a complex process. The analysis suggests that in order for companies to ensure their sustainability, they must find some sort of highly dynamic and transitory equilibrium for the core of the functional requirements from the demand side and the structural capacities for the supply. As a result, this reflection proposes that those decisions instrumented parting from these capacities, can be accepted within a broad range of efficient evolutionary stra¬tegies within a broad spectrum that goes from following orthodox economic methods as well as current innovation ones.
