What is a Reliability Program?
An effective reliability program defines optimal activities that will maximize the likelihood that a design will meet or exceed customer reliability requirements and company cost and schedule objectives. It includes realistic reliability requirements/goals, organizational responsibilities, holistic Design for Reliability (DFR) principles, and suitably tailored analysis, test and customer support approaches.

Surrogate Reliability Data
Surrogate reliability data is summarized data from field testing that is not performed in-house. Often, the data will estimate the failures under specified operating hours/miles under certain conditions for particular components that are either the exact match or a similar part an engineer must assess to perform a reliability analysis.

What is Reliability Data Collection and Analysis?
Data collection and analysis facilitates an understanding of field operational use profiles and environmental stress data and is critical for ensuring design/process robustness. Collection and analysis of failure data to root failure cause identification and mitigation is critical to ensure product/process reliability growth and success over its life cycle.
