A formal mathematical model of the system specification

An initial version of a system used to demonstrate concepts, try out design options, and find out more about the problem and its possible solutions

Correct Answer

An initial version of a system used to demonstrate concepts, try out design options, and find out more about the problem and its possible solutions

Explanation

A prototype is an initial version of a software system used to demonstrate concepts, try out design options, and find out more about the problem and its possible solutions. Rapid, iterative development of the prototype is essential so that costs are controlled and stakeholders can experiment with it early.
