Using complete field-based data, a reliability engineer has analyzed the reliability growth of a repairable system over the last 24 months. The analysis suggests a "no growth" condition, and that finding is reported to management.
Due to a pending multimillion dollar order, management requests that a line be drawn to show growth where none actually exists. The engineer's department manager directs the engineer to comply with management request.
According to the ASQ Code of Ethics, which of the following is an appropriate action for the engineer to take next?
