Which entitlement model is appropriate when customers are entitled to phone support for one year after purchasing a product?

The entitlement model that best fits the scenario of customers being entitled to phone support for one year after purchasing a product is the entitlements model. This model allows organizations to define the support levels and types that customers are entitled to, based on their interactions and purchases.

In this scenario, since the customer has purchased a product, the entitlement can specifically outline that they are eligible for phone support for a duration of one year. Entitlements can also track the usage of support interactions and ensure that customers receive their entitled services, fostering a better customer experience.

While other models like service contracts, support agreements, and product warranties may address different types of customer support or protections, they do not explicitly cater to the specific tracking of support rights as defined in the entitlement model. Service contracts primarily deal with broader service terms and conditions, while support agreements may not necessarily highlight time-specific entitlements, and product warranties generally cover defects or malfunctions rather than service or support interactions. Therefore, entitlements are the most appropriate choice in this context.
