The VRIO framework is a useful tool for assessing core capabilities. It stands for Value, Rarity, Imitability, and Organization, and it helps to determine whether a capability is a source of sustainable competitive advantage for an organization. To evaluate a capability, you must consider four criteria: Value, which looks at whether the capability enables the organization to create value for its customers and stakeholders; Rarity, which examines whether the capability is rare or scarce among competitors; Imitability, which assesses whether the capability is difficult or costly to imitate; and Organization, which evaluates whether the organization is able to exploit the capability effectively and efficiently. If a capability meets all four criteria, it is considered a core capability and gives the organization a sustainable competitive advantage. If it meets some but not all of the criteria, it is considered a temporary or potential advantage, and may require further development or protection. If it meets none of the criteria, it is considered a disadvantage and may need to be eliminated or improved.
