Many organizations today are focusing their resources on the most dominant failure pattern in their operation instead of reacting to problems. Identify the most dominant failure pattern allows a company to focus on the common thread which has the largest impact on asset integrity.

The US Navy conducted a study of their assets and found the most dominant failure pattern was infant mortality and considered the findings to be unacceptable. They put forth an effort to reduce infant mortality of their assets from over 60% to 6% and were successful in accomplishing it.

Focusing on the dominant failure pattern causes an organization to identify the common thread between different types of assets and impacts asset integrity overall in an effective manner. The failure patterns shown below were conducted back in the 1960s by Nolan and Heap with United Airlines. Many companies have found these failure patterns to be same across most industry verticals.
