According to the PMI Professional in Business Analysis objectives and content, a prototype is a tool that can be used to demonstrate the features and functionality of a product or solution in an iterative manner. A prototype can help to elicit, validate, and verify requirements, as well as to obtain feedback and approval from stakeholders. A prototype can also help to reduce risks, errors, and rework, and to increase customer satisfaction and quality. A proof-of-concept model is a type of prototype that is used to test the feasibility and viability of a product or solution. A proof-of-concept model can help to show the benefits and value of the product or solution, and to identify any technical or business challenges or constraints. References:
