VRIO
The VRIO framework, in a wider scope, is part of a much larger strategic scheme of a firm. The basic strategic process that any firm goes through begins with a vision statement, and continues on through objectives, internal & external analysis, strategic choices (both business-level and corporate-level), and strategic implementation. The firm will hope that this process results in a competitive advantage in the marketplace they operate in. VRIO falls into the internal analysis step of these procedures, but is used as a framework in evaluating just about all resources and capabilities of a firm, regardless of what phase of the strategic model it falls under. VRIO is an acronym for the four question framework you ask about a resource or capability to determine its competitive potential: the question of Value, the question of Rarity, the question of Imitability (Ease/Difficulty to Imitate), and the question of Organization (ability to exploit the resource or capability).
