Chapter 23: List of Common Manufacturing KPIs

Summary: KPIs align operations to business outcomes by quantifying throughput, quality, cost, and service. Manufacturers and suppliers need a concise, consistent set that guides daily decisions and long-term investments. KPI definitions should be standardized, auditable, and tied to financial impact. This chapter presents a practical KPI taxonomy and how to operationalize it across sites and systems.

Context and Scope: Applicable to discrete, process, and hybrid plants. Focuses on production, quality, maintenance, supply chain, and sustainability metrics governed via ERP/MES/QMS/CMMS and data platforms.

Key Concepts:

Leading vs Lagging: Predictive indicators (e.g., changeover readiness) vs outcomes (e.g., OEE).
Normalization: Adjusting metrics by product mix, shift, or site to compare fairly.
Data Quality: Complete, timely, and consistent data feeding KPIs.
Visualization: Tiered dashboards from cell to enterprise.

Standards and Regulations:

ISA-95 equipment states inform OEE and downtime categorizations.
ISO 9001 and IATF 16949 drive quality tracking and documentation.
ISO 50001 guides energy intensity metrics.

Architecture/Processes:

Data pipeline consolidating MES/SCADA, ERP, QMS, and CMMS.
KPI calculations as curated data products with lineage.
Governance for definitions, thresholds, and review cadences.

Data and Interoperability:

Canonical schemas for orders, equipment, quality events, and energy.
APIs and semantic layers enabling self-serve analytics.
Time alignment and context (shift, product, line) for comparisons.

Security and Compliance:

Access controls and SoD for KPI definitions and data.
Audit trails of changes to calculations and thresholds.
Evidence repositories for customer and regulatory audits.

KPIs and Metrics:

OEE; Availability/Performance/Quality components.
First-Pass Yield, Scrap Rate, and Cost of Poor Quality.
MTBF/MTTR, Planned vs Unplanned Downtime.
Schedule Adherence, On-Time Delivery, Order Cycle Time.
Inventory Turns, Days of Supply, Backorder Rate.
Energy Intensity per Unit, Peak Demand, Carbon Intensity.

Implementation Checklist:

Select a lean, high-impact KPI set per site/vertical.
Define formulas and contexts; publish in a data dictionary.
Build validated KPI data products with lineage.
Instrument tiered visual management and alerts.
Review KPIs in daily/weekly tier meetings; act on gaps.
Audit definitions quarterly; align to financials.

Common Pitfalls and Mitigations:

Too many KPIs: Focus on a critical few with owners.
Inconsistent definitions: Govern centrally; enforce in tools.
Vanity metrics: Tie to throughput, cost, quality, or risk reductions.
Stale data: Monitor freshness; set SLAs for pipelines.
