From a Resource-Based Perspective, company competitiveness critically depends on assets accumulated by the organization. The focus of analysts often concentrates on the so-called ''innovation capacities.''

The present work aims at contributing to this issue by developing a capacity assessment methodology. It presents an evaluation methodology that integrates three components: a conceptual model based on a systemic approach to companies that borrows the conceptual proposal of Nadler and Thusman, and develops a characterization of capacities; a metric developed based on the Capability Maturity Model (CMM); and an implementation instrument based on semi-structured interviews
