Consider the process for scheduling class offerings at a small university such as Bentley. There are two hundred faculty who offer close to a thousand courses every year. The actors and roles involved in this process include the registrar's office, facilities, department chairs, and several others. Which of the following represents the right approach to improving the process? Draw on your knowledge of lean and six sigma techniques to answer the question.

A$.$ Bring in a consultant and listen to possibilities for minimizing variations in outcomes with techniques such as detecting defects with DPMO calculations.

B$.$ Bring in a consultant and listen to possibilities for making it a lean process with techniques such as Critical to Quality $($CTQ$)$ that focus on the customer.

C$.$ Bring in a consultant to consider how to use job rotation and other techniques to improve customer satisfaction.

D$.$ None of these techniques are appropriate in a setting such as a university course scheduling process because the process is unique.
