3.2 Failure Codes Flashcards
What is done in the Failure Codes application?
Build and display failure hierarchies
What do Failure Hierarchies help construct?
An accurate history of the types of failures that affect assets and operating locations
How are Failure Codes helpful for a business?
After analyzing and reporting failure trends, preventive measures can be taken
Failure Hierarchy
What can failure data be used for?
Record and view asset and location problems, causes, and remedies associated with work orders
Failure Hierarchy data
What ability does this provide?
Identify trends and isolate probable causes of breakdowns
Failure Hierarchy data
What can this be used to analyze?
Reliability of vital equipment components
Failure Data
What can this be correlated with?
Give example
Preventive maintenance schedules
Failure data
Can be used to review the history of [fill in the blanks]
asset and location failures
Failure Data
What key aspects can this be used to review?
2 things
- breakdown trends
- mean time between failures
Failure Data
How can failure information be used to reduce or limit asset and location failures over time?
3 steps
- Review history
- Identify breakdown trends & mean time b/w failures
- Correlate this with other data
Where can failure data information be viewed for an asset?
Failure Reporting tab of Assets application
What can be specified, in addition to failure data information, for an asset?
- Component-level failures
- Failure mechanism codes in support of ISO 14224
- Safety-related system failures
What is created in the Failure Codes application?
Failure hierarchies
What must failure data belong to?
One or more failure hierarchies
What is a failure hierarchy?
Organized set of data on problems, causes, and remedies related to assets and locations
What is your failure hierarchy identified by?
Top-level Failure Code, called the Failure Class
What is the default failure class value on a work order?
If the asset or location on the work order is associated with the failure class, that will be the default failure class value
How does a failure hierarchy work?
i.e. How is it built?
Uses an organized structure of codes given to a particular asset or location
At what stages of the work management process can failure coding be done?
- Initiation of the work order
- Record creation of assets, items, or locations
Examples of Problem Codes
- Excessive vibration
- Fluid leak
- Too hot
- Not Running
Failure Coding in Work Management Process
Initiation of the Work Order
Describe
Enter the appropriate failure class and problem code prior to performing any maintenance
What is the coding structure in a failure hierarchy used for?
Identify and quantify maintenance and failure patterns with similar assets
What does failure coding allow?
Quantified measurements to determine new maintenance practices or to influence purchasing decisions
List the 4 levels of failure codes
- Failure class
- Problem code
- Cause code
- Remedy code
Failure Coding in Work Management Process
Record creation of assets, items, or locations
Describe
Can associate classes to make the [work management] process simpler and more consistent.
Define Problem Codes
Sense-based means of identifying that something is wrong with an asset.
Problem Codes identify [fill in]
the type of problems seen when the work was identified
True/False: For a given Problem, there can be 1 or more Cause Codes assigned
True: Can have a many-to-one relationship
When are Cause Codes determined?
Further inspection of the asset
Purpose of cause codes
Indicate the root or determine the cause of the identified problem
Examples of cause codes
For a given Problem
Fluid Leak problem
–> Could have the following possible Cause Codes:
- Damaged housing
- Worn gasket
- Loose connector
Remedy Codes
Detail the means by which a particular cause was addressed
True/False: For a given Cause Code, there can only be one associated Remedy Code
False
There can be a many to one relationship between a cause and its remedy set.
Remedy code example
For a given Cause
Loose Connector cause
Possible remedies:
- Replace the asset connection
- Replace inlet connection
- tighten connector
- align connection
- apply sealant
True/False: Failure Codes can be reused
True: Failure codes can be reused among many similar asset types.
True/False: Failure hierarchies should be 100% specific to a particular asset
False: Failure hierarchies should not be 100% specific to a particular asset
Example of reusing Failure Codes
All pumps can leak or fail to start - they would have similar general causes and remedies for generic problems such as these.
Failure Class for a fluid pump can be the same if constructed as such - regardless of specific fluid pumped, or particular sub-class of pump (centrifugal, screw type, etc.)
True/False: Failure Classes are Site-Specific
False: Failure Classes are Organization-Specific
How is the Organization on a Failure Class record determined?
Crosses in from user’s default insert site information
True/False: Failure hierarchies should be created as you go along in creating records in Maximo
False: Strongly recommended to create what you expect the various hierarchies to look like prior to entering records in Maximo
