Case Management - Failure Modes tab - HxGN EAM - 12.1.1 - Feature Briefs - Hexagon

On this tab, typically used for a root cause analysis, you can add multiple failure modes. The failure modes that you collect here share most of their attributes with the failure modes on the RCM tabs of the equipment screens. And that is no coincidence, because the intention is to collect this information here and then apply it to the RCM tab of selected equipment. A continuous loop of improvement:

• Equipment fails.

• Work order is created to fix the equipment.

• A case is created for the work order to perform a root cause analysis.

• During the case

  • The root cause is found.

  • A new failure mode is identified.

  • This failure mode is used to update the RCM tab of relevant equipment.

  • This includes any mitigation activities.

• Equipment less likely to fail this way again.

And rather than small improvements to the RCM tab over time, this same approach can also be used to setup the RCM tab for equipment initially. An explanation of these RCM features can be found in the EAM RCM brief.

To define the RCM tab the system needs to collect additional data on top of the failure mode related attributes. These attributes are:

1. RCM Level—RCM Level can be defined on the Organizations screen. And based on the Organization selected for the case it will default the found value here. Otherwise, if no value was found, you can choose between a Risk Analysis, a FMECA, or Classic RCM. However, it is also possible that you cannot enter this value and the system decides for you. This will happen if:

   1. One or more records already exist on this tab.

   2. Or if the Equipment select on the Record View has RCM Level filled in already.

   The system will keep using the same value for any new records in both cases.

2. RCM Project—The project is automatically determined. The system will find it in the following sequence:

   1. The RCM Project of the Organization of the Equipment select on the Record View.

   2. If nothing is found, the RCM Project of the Organization of the case.

   3. If still, nothing is found, the system default project (System Codes screen Entity STPR).

      And just like for the RCM Level, the system will keep using the same value for any new records that are added.

   The RCM function is required because it is also defined on the RCM tab of the equipment screens and is required for a Risk Analysis, a FMECA, and for Classic RCM. Collect function related data on this tab as follows:

3. Function—Describe the function of the equipment. If you enter a value here the system will automatically assign a Function Code. Any other records where you enter the same exact value will all get the same Function Code as well. The system will automatically keep track of these for you.

4. Existing Function—If the Equipment on the case Record View already has functions defined on the RCM tab, you can select one of them in this field. You can only have one function per record. So, if you fill in this field the system will clear Function, and vice versa, if you clear this field you must enter Function.

5. And consistent with the RCM tab of the equipment screens, you can also collect the following function related attributes:

   1. Function Sequence—Used to order the Functions in the RCM tree.

   2. Function Note—Free format additional information.

   3. Primary—Select if the function is the primary. The system will allow selection of multiple if needed.

   The functional failure is required because it is also defined on the RCM tab of the equipment screens but is only required for a Risk Analysis or Classic RCM and is not used for a FMECA. Collect functional failure related data on this tab as follows and only for a Risk Analysis or Classic RCM:

6. Functional Failure—Describe the functional failure of the equipment. If you enter a value here the system will automatically assign a Functional Failure Code. Any other records where you enter the same exact value will all get the same Functional Failure Code as well. The system will automatically keep track of these for you.

7. Existing Functional Failure—If the Equipment on the case Record View already has functional failures defined on the RCM tab, you can select one of them in this field. Since these are always attached to a function, you must first select the Existing Function. You can only have one functional failure per record. So, if you fill in this field the system will clear Functional Failure, and vice versa, if you clear this field you must enter Functional Failure.

8. And consistent with the RCM tab of the equipment screens, you can also collect the following functional failure related attributes:

   1. Functional Failure Sequence—Used to order the Functions in the RCM tree.

   2. Functional Failure Note—Free format additional information.

   3. Identifier—Functional failures are often identified with a letter. For example, A, B, C, etc.

   Then finally we have reached failure mode data. Failure modes are needed for a Risk Analysis, a FMECA, and for Classic RCM. Collect failure mode related data on this tab as:

9. Failure Mode—Describe the failure mode of the equipment. If you enter a value here the system will automatically assign a Failure Code.

10. Most other fields behave like they do on the RCM tab of the equipment screens. This includes:

    1. Probability

    2. Probability %

    3. Sequence

    4. Note

    5. Standard WO

    6. Downtime Hours

    7. Downtime Cost

    8. Failure Mode Library

11. The tab also works with the RCMPREFS organization option. Depending on the settings of this option the system may

    1. Hide the Failure Mode field and instead display the Noun, Verb, and Complement fields that together make up the Failure Mode.

    2. Hide or display the Effect Indicator and the Effect Consequence.

12. Root Cause Code—The work order closing codes are available as well, but rather than defining them on this tab you can use the data already record on the case Record View or any of the records from the Root Causes tab. Simply use this field and select the record that you want to use for this failure mode and the system will populate the work order closing codes in the Root Cause Details section of the screen.

    Buttons:

    1. Click any of the translate buttons to bring up the Translations pop-up so you can translate the relevant descriptions:

       1. Translate Function

       2. Translate Functional Failure

       3. Translate Failure Mode

    2. Edit Failure Consequences—This button will bring up the Failure Consequences pop-up. Consequences are defined against the failure mode or the functional failure depending on the RCM Level selected. The system will do this automatically. The only thing you need to worry about here is entering the Consequence, Consequence Cost, Sequence, and Note. So as expected, this pop-up collects the same data as it does on the RCM tab of the equipment screens.

       After entering Consequence and entering Probability on the Failure Modes tab, the system will calculate the resulting Risk Priority Number (=Consequence times Probability) and related Risk Level based on the risk matrix associated with the selected RCM Project.

    3. Failure Finding Interval—This button will bring up the Failure Finding Interval pop-up which allows you to enter data to determine the failure finding interval (FFI) for the selected failure mode. For details see the HxGN EAM RCM brief.

    4. Control Strategy—This button will bring up the Failure Mode Control Strategy pop-up which allows you to determine the control strategy for the selected failure mode. For details see the HxGN EAM RCM brief.
