Abstract
This paper examines the theoretical contributions on the firm’s resources and the articulation of competitive advantages, the firm’s value chain analysis, and the comprehension of the “intangible nature” of the firm in the discipline of the internal organizational environment analysis. The aim is to synthesize these approaches from a critical perspective and attempt to enrich them conceptually based on the “biological perception” and “physiology” of the firm. To this end, the Stra.Tech.Man approach, which exploits interpretatively a synthesis of the evolutionary spheres of strategy, technology, and management for the “living” socioeconomic organization, seems capable of unifying the previous approaches analytically and enrich them.
