A second definition of quality is fitness for use criteria, which focuses how well the product performs its intended function or use. For example, a Mercedes Benz and Jeep Cherokee both meet a fitness for use definition if one considers transportation as the intended function. However, if the definition becomes more specific and assumes that the intended use is for transportation on mountain roads and carrying fishing gear, the Jeep Cherokee has a greater fitness for use. You can also see that fitness for use criteria is a user-based definition: quality is defined as fitness for intended use, or how well the product performs its intended function.
