Step-by-step explanation:
A substitute is a good or service that can be used in place of another. In the context of the VRIST framework, a substitute for a resource is another resource that can provide comparable value-creating benefits to a product or service. It serves the same function for a customer and is deployed by the firm when the original resource is no longer available.
For example, if a company relies on a specific raw material for its manufacturing process but that material becomes scarce or unavailable, the company may search for a substitute resource that can serve the same purpose. This substitute resource could be a different material that can be used to create a comparable product.
