FFT (Failure Finding Task)
- Last UpdatedDec 02, 2024
- 2 minute read
A Failure Finding Task aims at finding hidden failure during planned maintenance actions. It is a kind of inspection task that can be defined explicitly to give adequate focus to such an activity.
Behavior
The behavior of an FFT is like that of the CBM task which also defines inspection related data. The difference is, however, that CBM focuses on performing inspections to prevent failure, while the FFT aims at finding hidden failure, and act on it before actual harm is done.
Enabling FFT
FFT is an optional function that can be enabled company wide (using the desktop version of Asset Strategy Optimization) whenever the customer feels the need to extend the object set with the possibility to define Failure Finding Tasks.
FFT and FFT Follow-up
As with the CBM follow-up, the action that is to be performed when hidden failure is detected during inspection, is an FBM action that is defined as the FFT Follow-up. The FFT Follow-up can be defined as a child object of the FFT, or it can be copied from an existing FBM by dragging the FBM and dropping it onto the FFT object. In the latter case, the copied FBM will be automatically converted into a child FFT-follow object.

FIELD |
DESCRIPTION |
|
Description |
Users are free to enter any description for the object. The logical option is to describe the preventive action performed. |
|
Number |
A maintenance action can be numbered. When configured, the number will be listed in the tree with the description of the FFT. |
|
Maintenance time/unit |
Duration of the maintenance action. Select an appropriate unit of time. |
|
Mandatory |
This field can be set to indicate that the modeled maintenance is mandatory, for example because of legislation. Marking it as mandatory is a signal that the maintenance should not be changed or removed without careful consideration. |
|
Interval |
Frequency with which the failure finding task is carried out (choose also the time unit) |
|
Costs*) |
Costs can contain different sections: Maintenance Category, Cost Categories, and Total Costs |
|
Maintenance category |
Select here from Minor maintenance, Major maintenance and Renewal. |
|
Cost categories |
The options to enter in this field are predefined. Categories can be defined in the desktop version. Examples of cost categories include personnel, material, and equipment. |
|
Total costs |
This field has a dual function: If cost categories are not used, the user may enter a cost value directly in this field. If costs have been specified using the cost categories, then this field will automatically show the sum of these values; in this case the field will be read-only; only when all the values in the cost categories have been reset to 0, will the field Total costs become editable again. |
|
Environmental Impact |
Based on the categories configured in System Options, the impact categories appear. In the field, enter the category value to calculate the Total CO2e. To know about this option, see the topic Environmental Impact. |
|
Free Fields*) |
If Free fields are enabled in the desktop version, each of the fields will be shown here and can be edited dependent on the user rights. |
|

These fields should be enabled in the desktop versions. See also: Other information. |
