On the RCM tab of the equipment and location screens, you can perform the Risk Assessment, Risk Analysis, or FMECA. The tab shows the assessment, analysis, or FMECA in hierarchical form. You build the RCM tree top-down using the following popups:
-
Add/Edit Functions - Add new Functions, or edit existing ones, by clicking the Add/Edit Functions button. Once the Functions screen is up, specify the following information:
-
Description - Enter the description of the Function.
-
Sequence - Use the Sequence to order the Functions in the tree. Otherwise they will be listed alphabetically.
You can enter some background information regarding the Function.
-
RCM Project - References the RCM Project and indirectly the Risk Matrix in use for the assessment or analysis.
-
-
Add/Edit Functional Failures - After you have added one or more Functions you can add new Functional Failures, or edit existing ones, by clicking the Add/Edit Functional Failures button. Once the Functional Failures screen is up, specify the following information:
-
Description - Enter the description of the failure.
-
Function - Every Functional Failure is always attached to a Function. You can pick any Function defined for the equipment.
-
Probability - Enter the probability of the failure. This field is only available on this screen if this concerns a Risk Assessment, which is determined by the selected RCM Level on the equipment screens.
-
Probability % - Defaults from the selected Probability but can be changed if needed. This field is only available on this screen if this concerns a Risk Assessment.
-
Sequence - Use the Sequence to order the Functional Failures in the tree. Otherwise they will be listed alphabetically.
-
You can enter some background information regarding the failure.
-
Note that for a FMECA functional failures cannot be used. Use failure modes instead.
-
-
-
Edit Failure Consequence - After you have added one or more Functional Failures, or Failure Modes in case of a FMECA, you can edit Consequences by clicking the Edit Failure Consequences button. Once the Failure Consequences screen is up, specify the following information:
-
Consequence - Enter a Consequence for the Consequence Category. There is a lookup available (F9).
-
Consequence Cost - Defaults from the selected Consequence but can be changed if needed.
-
Sequence - Use the Sequence to order the Consequence Categories in the tree. Otherwise they will be listed alphabetically.
You can enter some background information regarding the consequence.
-
-
Add/Edit Failure Modes - Add new Failure Modes, or edit existing ones, by clicking the Add/Edit Failure Modes button. You can only add Failure Modes if you have selected to perform a Risk Analysis or FMECA (RCM Level on the equipment screens). Once the Failure Modes screen is up, specify the following information:
-
Description - Enter the description of the Failure Mode.
-
Function - Every Failure Mode is always attached to a Function, but only if you selected FMECA. You can pick any Function defined for the equipment. Otherwise, if Risk Analysis was selected for the header equipment, this field will be hidden.
-
Probability - Enter the probability of the Failure Mode.
-
Probability % - Defaults from the selected Probability but can be changed if needed.
-
Sequence - Use the Sequence to order the Failure Modes in the tree. Otherwise they will be listed alphabetically.
You can enter some background information regarding the Failure Mode.
-
RCM Project - References the RCM Project and indirectly the Risk Matrix in use for the analysis.
In the Work Order Details section on this screen several work order related fields can be entered. This includes all closing codes (symptom, problem, failure, cause and action codes), Standard WO, Downtime Hours, Downtime Cost, and the following codes:
-
Tactical Cause - System Codes Entity ‘TACA’.
-
Human Factor - System Codes Entity ‘HUFA’.
-
Workmanship - System Codes Entity ‘WOMS’.
-
Human Oversight - System Codes Entity ‘HUOV’.
-
Method of Detection - System Codes Entity ‘MOFD’.
If you select a failure mode on the work order screen, all these values will default if they have a value. On the work order request screen, because most fields are hidden from the user there, these defaults are still applied but now in the background and invisible to the user.
There are some hidden features on the Failure Modes popup. These features can be activated on the Options tab of the Organizations screen. Select the RCMPREFS option and depending on the selections you make the following fields will show:
-
-
Noun - This is a lookup. On the System Codes screen use Entity ‘DSCF’ (Description formatting) to add nouns to your list. System Code is ‘FMN’.
-
Verb - This is also a lookup. Verbs are configured the same way as nouns. They just use a different System Code which is ‘FMV’.
-
Complement - Free text field.
With these three fields, the system will automatically generate the Description for you by concatenating the noun, the verb, and the complement, making sure the total length does not exceed the allowed maximum. This way the Description contents and formatting will be very consistent, which makes it also easier to search and compare.
-
Effect Indicator - Free text field where you can describe what indicators are present to verify that the failure mode has manifested itself. A vibration or high pressure for example, or loud noises.
-
Effect Consequence - Free text field where you can describe the consequences of the failure mode. Note that this field is not relevant for the calculation of the Risk Priority Number. That remains based on the selections you make on the Edit Failure Consequence popup.
-
-
Add/Edit Functional Failures for Failure Modes - This is the last step in the analysis where you can associate one or more Functional Failures to any of your defined Failure Modes by clicking the Add/Edit Functional Failures for Failure Modes button. Once the Functional Failures for Failure Modes screen is open enter:
-
Failure Mode - Select a Failure Mode. You can pick any Failure Mode defined for the equipment.
-
Functional Failure - Select the Functional Failure. You can pick any Functional Failure defined for the equipment.
-
Sequence - Use the Sequence to order the Functional Failures in the tree. Otherwise they will be listed alphabetically.
You can enter some background information regarding the relationship between Functional
Failure and Failure Mode.
-
Once your tree is complete use the Expand All and Collapse All buttons to quickly expand and collapse the tree.
This tab also supports the import of RCM data from equipment and RCM Templates. For details on this please see the RCM Templates section of this brief.
