Assumptions used in field reliability data analysis may be seldom made explicit or questioned in practice, yet these assumptions affect how engineering managers develop metrics for use in long-term support contracts. To address this issue, this article describes a procedure to avoid the pitfalls in employing the results of field data analysis for repairable items. The procedure is implemented with the aid of a simplified example based on a real case study in defense avionics and is streamlined so that the computations can be replicated in other applications.
