The document outlines the importance of effective maintenance work procedures and emphasizes that they should be clear, repeatable, measurable, and adhered to in a disciplined manner. It discusses factors affecting human performance, the need for standards, and the value of effective procedures in providing reliable work execution. Recommendations include reviewing existing strategies, modifying procedures to meet standards, and measuring their performance to ensure optimal reliability in maintenance operations.

1. Effective Maintenance Work Procedures

Recommendation: Review “Failure Modes Driven
Strategy – Tool Box Training Session” first
Effective Work Procedures are key to  Having the ability to effect work execution
without spending money of training everyone –
success in Work Execution the procedure becomes training document.
 Knowing how you can change a procedure
