VRIN framework

The VRIN framework is a tool used by businesses to evaluate their resources and capabilities to gain a competitive advantage. It stands for Valuable, Rare, Inimitable, and Non-substitutable. Resources that are valuable help the company meet customer needs, rare resources are not widely available to competitors, inimitable resources are difficult to copy or imitate, and non-substitutable resources cannot be replaced by alternatives. When a company's resources meet all these criteria, they can create a sustainable competitive advantage, enabling the business to outperform rivals over time.
