Chapter 8. Work Management 159 Figure 8- 16 Example of a failure hierarchy for pump failures 8.4.2 Assets and locations failure class The Assets and Locations applications, which are respectively opened by selecting Go To . Assets . Assets and at Go To . Assets . Locations, can define a failure class for assets and locations, respectively. This enables a work order to define a problem cause considering the failure class of its working assets. Figure 8- 17 on page 160 shows an example of the Centrifugal Pump asset that defines the Pumps failure class, previously shown in Figure 8- 16. Note: A failure hierarchy is defined by a failure class, which can be described by problems, causes, and remedies.
