Theory Meets Practice: Using The Potter Box To Teach Business Communication Ethics 
This paper introduces the Potter Box, a grounded and easy to use method of ethical decisionmaking. The rationale for this technique is seen in the current crisis in business ethics and education in ethical behavior. The Potter Box was developed by Dr. Ralph Potter, Harvard University theologian, grounded in the work of sociologist Talcott Parsons. This device has been used in assessing journalistic and public relations decisions, but can readily be used in the practice and criticism of business communication. The four portions of the Potter Box are explained in terms of eight explicit steps. A case study is presented for use in the classroom.
