Tangible approximation of the product.
May exhibit unmodeled behavior.
Some behavior may be an artifact of the approximation.
Often best for communication.
Mathematical model of the product.
Can only exhibit behavior arising from explicitly modeled phenomena. (However, behavior is not always anticipated.
Some behavior may be an artifact of the analytical method.
Often allow more experimental freedom than physical models.Physical vs. Analytical Prototypes
Implement one or a few attributes of the product.
Answer specific questions about the product design.
Generally several are required.
Implement many or all attributes of the product.
Offer opportunities for rigorous testing.
Often best for milestones and integration.Focused vs. Comprehensive Prototypes
