Continual Improvement of an AMS Based on ISO 55001
What the exam tests
Clause 10: nonconformity and corrective action, and continual improvement. The examiner wants root cause analysis and effectiveness verification, not apology-driven paperwork.
Core rules
- Reaction: control and correct the nonconformity and deal with the consequences.
- Evaluation: assess the need for action to eliminate causes so the problem does not recur or appear elsewhere; investigate, determine causes and check whether similar nonconformities exist.
- Action: implement, review effectiveness, update risks in planning if needed, and retain documented information.
- Continual improvement: improve the suitability, adequacy and effectiveness of the AMS; use monitoring data, audits, reviews, benchmarking and maturity assessment to select opportunities. Corrective action fixes a defect; improvement raises capability.
- Improvements should be managed as changes with resources and measures.
Worked example
A critical compressor fails twice in one quarter. Correction: repair. Root cause analysis (5 Whys) finds the lubrication route was never updated after the machine was relocated; the underlying cause is a change-management weakness. Corrective action updates the route and adds equipment relocation to change control; effectiveness is verified through three subsequent oil-analysis results. Reasoning: only the process fix prevents recurrence; the repair alone is correction.
Traps
"Retrain the operator" as a default root cause; closing actions without effectiveness checks; confusing correction with corrective action; improvement plans unlinked to objectives; treating every audit finding as automatically a clause 10 nonconformity.
