158 Certification Study Guide Series: IBM Maximo Asset Management V7.1 8.4 Failure class Failure class identifies failure hierarchies, which helps you to track the failures that affect assets and operating locations. Using this information can help you to take preventive measures and to analyze failure trends. This classification can be related in assets and locations when it is necessary to report work done on them. The Failure Codes application is used to create failure classes, whose structure defines failure hierarchies. To open this application, select Go To . Assets . Failure Codes. 8.4.1 Hierarchy The Failure Codes tab in the Failure Codes application is used to build, view, modify, and delete failure hierarchies. A failure hierarchy is an organized set of data about problems, causes, and remedies related to assets and operating location failures. The failures hierarchies classify possible failures for assets and operating locations when building work orders. A failure class is defined by the following hierarchy: Problems, which define problems for the failure class Causes, which define causes for each problem Remedies, which define remedies for each cause Figure 8- 16 on page 159 shows an example of a failure class hierarchy for pump failures. Four related problems are shown. For the stopped problem, three causes are described. One remedy is defined for the breaker tripped cause.
