QUESTION 213
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.
The system is released without improvements and the company receives the multimillion dollar order from an external customer. The customer then requests evidence of the reliability growth. Which of the following actions by the engineer would be MOST appropriat?
