Definition
A practical criticality framework for MRO, production and service-risk items. This reference is designed for practical industrial stores, MRO, production and materials-management environments.
Objective
Protect operational continuity by classifying items according to consequence of non-availability.
Scope
Apply the method at item, category, location or plant level as appropriate. The control should connect planning, purchasing, stores transactions, physical verification and management review.
Required Inputs
- Equipment criticality
- production impact
- safety/environmental impact
- alternate availability
- repair lead time.
Methodology
- Define the business requirement, scope and review period.
- Validate item master, consumption, stock and open transaction data.
- Calculate or classify using the defined method.
- Compare the result with criticality, supplier constraints and future demand.
- Assign an action owner, due date and review frequency.
- Monitor KPI movement and revise parameters when conditions change.
Formula / Control Logic
Worked Industrial Example
A low-cost bearing may be Vital if failure stops a critical line and no substitute is available.
Decision Rules
- Document the reason for Vital status.
- Review criticality with maintenance/engineering.
- Link Vital items to service and emergency procurement controls.
Industrial Controls
- Authorized master-data and parameter changes
- ERP transaction discipline and document traceability
- Physical verification and reconciliation
- Exception reporting with named ownership
- Periodic management review of ageing, service and capital exposure
KPIs
Service
Availability, fill rate and stock-out performance.
Accuracy
Book-to-physical reliability and transaction quality.
Capital
Turnover, coverage, ageing, excess and dead stock.
Common Errors
- Making every item Vital.
- Using purchase value as a proxy for criticality.
- Failing to maintain alternate/substitute information.
Excel / MIS Application
Useful fields: Item Code, Description, UOM, Opening Qty, Receipt Qty, Issue Qty, Closing Qty, Unit Rate, Annual Consumption, Current Stock, Open PO, Lead Time, Safety Stock, ROP, Min, Max, ROQ, ABC, VED, FSN, Ageing, Action.
Management Review Questions
- Which items require action now, and why?
- Are open orders aligned with actual requirement?
- Which exceptions are recurring and what is the root cause?
- Which parameter should be changed, and what evidence supports the change?
