A value-added step in a process is defined by three characteristics. First, the step must be something that the customer is willing to pay for. Second, the step must directly change the form, fit, or function of something to produce a product or service. The final characteristic of a value-added step is that it is so important that it must be done right every time to successfully produce the intended product or service.
