Chartered Property Casualty Underwriter (CPCU) is a professional designation in property-casualty insurance and risk management.
A prototype is an early sample, model, or release of a product built to test a concept or process or to act as a thing to be replicated or learned from.It is a term used in a variety of contexts, including semantics, design, electronics, and software programming. A User Experience Prototype captures enough aspects of the intended design that it can support user research. 2  A Visual Prototype captures the size and appearance, but not the functionality, of the intended design.
As a model of the new system a prototype allows for several forms of communication. First, it allows the developers to communicate to the users their understanding of the requirements. (Obviously before a prototype can be built there must be some initial requirements discussions between developers and users).
