The flowchart begins with a box stating “Analyse the results from maintenance process”, followed by a decision diamond comparing “N f greater than N t”, where a “No” arrow leads to a box reading “Continue with existing policy” and a “Yes” arrow leads downward to a box labeled “F M E C A”; the next decision diamond compares “C r greater than C r t, where a “No” arrow again leads to “Continue with existing policy” and a “Yes” arrow leads to “Root cause analysis”, followed by a final box labeled “Recommend preventive actions”. An arrow points from this flowchart to the funnel diagram, which contains overlapping circles labeled “Equipment and system design”, “Condition monitoring or analytics or predictive technology”, and “Spare parts or maintainability or tools”, all feeding into a lower output labeled “Preventive maintenance strategy (interval based or condition-based)”.Maintenance policy assessment and maintenance policy improvement process
