At a very basic level, a product involves the delivery of a benefit or a service. A starting point for defining product requirements is to figure out the purpose of the product and its recipients. The purpose is primarily about identifying what benefits and services are meant to be delivered and how these are meant to help the product recipients.
The next level of defining product requirements deals with defining how eligibility and entitlement for the benefits and services can be effectively determined. This includes identifying the rules for determination, the information that must be captured about potential product recipients. This information is compared to the rules in order to make decisions.
A third level to product requirements is to think about how these decisions will be conveyed. Just as essential to determining eligibility and entitlement for benefits and services is the ability to understand how a person's circumstances have resulted in these eligibility and entitlement results. Without this insight, it is very difficult to see how these products meet the needs of its recipients.
In summary, the overall aim of delivery a product is to come up with a view over the lifetime of the case that will contain the "three Es" (Eligibility, Entitlement, Explanation). This concept is discussed in more detail in Inside Cúram Eligibility and Entitlement Using Cúram Express Rules.
