64: Documentation Content Inaccurate or Incomplete
Definition/Typical Issues
Were there errors or omissions in the content of the documents?
Were there errors or omissions in the documents? Do documents used in the field have markups to make them useful?
Were logs, work requests, work orders, or other formal documentation incomplete?
Do logs, work requests, work orders, and other work control documents contain insufficient detail?
Examples of documents that are addressed by this node include:
- Operator logs
- Computer logs
- Work requests
- Work orders
- Batch sheets
Examples
Example 1
- A flow meter in a product line failed, resulting in the wrong amount of material being sent to a customer. Records indicated that calibration of the flow sensor had been performed three times in the last month, but did not indicate how much of an adjustment was made during calibration. A large adjustment, or larger adjustments each time the maintenance was performed, might have indicated an impending failure.
Example 2
- During the past year, the failure rate for the feed pumps has doubled. Maintenance records are inaccurate to determine why any of the failures occurred. Work records just say "pump repaired."
Typical Recommendations
- Develop a system to control and track operator logs, computer logs, work requests, batch sheets, and other operational and maintenance history records.
- Periodically audit operator and maintenance logs for completeness.
- Develop methods for controlling access and changes to documents.
- Develop methods for approving changes to documents.
- Ensure that ongoing work is well communicated to unit operators and other potentially affected employees.
- Develop a nonroutine work permit or similar system to control all nonroutine work activities, even if no other safe work procedure or permit applies (subject to specific exemptions for certain plant areas and/or low-hazard tasks).
- Establish work requests in the computerized maintenance management system based on the reliability program.
- Modify the work requests to reflect changes to the facility.
- Review completed logs and reports and, based on the results of the review, take steps to improve their accuracy and completeness.
