KPI documentation

KPI documentation is the controlled set of records that define, explain, and govern how key performance indicators (KPIs) are selected, calculated, visualized, and maintained within an organization. In industrial and regulated manufacturing environments, it provides a common reference so that performance metrics are interpreted consistently across sites, systems, and functions.

What KPI documentation typically includes

Although formats vary, KPI documentation commonly contains:

• Metric definition: name of the KPI, a clear description, and its purpose (for example, on-time delivery, scrap rate, OEE).
• Calculation logic: formulas, time basis (shift, day, batch), data sources (MES, ERP, QMS), inclusion/exclusion rules, and handling of rework or special cases.
• Data ownership and responsibilities: who maintains the KPI definition, who validates data quality, and who reviews the results (e.g., production, quality, supply chain).
• Collection and reporting method: how data is captured (manual entry, automated tags, integrations), where KPIs are displayed (dashboards, reports), and update frequency.
• Scope and boundaries: which plants, product families, work centers, or suppliers are covered, and any explicit exclusions.
• Governance and revision history: approval paths, effective dates, change history, and links to supporting procedures or standards.

Role in industrial and regulated environments

In manufacturing settings, KPI documentation helps align how operational performance is measured across OT and IT systems. For example, it can specify whether downtime events from an MES are categorized as planned or unplanned, or how nonconformances from a QMS feed yield and cost of poor quality KPIs. In regulated sectors, documented KPI definitions can also support audit readiness by showing that metrics used in management review, continuous improvement, or supplier monitoring are consistently defined and controlled.

Operational use

On a day-to-day basis, KPI documentation is used to:

• Configure dashboards and reports in MES, ERP, or analytics tools according to approved formulas and filters.
• Onboard new engineers, supervisors, and analysts so they interpret metrics such as OEE, NPT, or on-time delivery in the same way.
• Support problem-solving and continuous improvement by making clear how changes on the shop floor will affect specific KPIs.
• Provide evidence during internal or external reviews that performance metrics are based on traceable, governed definitions.

Common confusion

• KPI documentation vs. KPI dashboard: A dashboard is the visual output that shows KPI values. KPI documentation describes how those values are defined and calculated. Dashboards should be configured to match the documented definitions.
• KPI documentation vs. procedures or work instructions: Procedures and work instructions describe how work is performed. KPI documentation describes how performance of that work is measured. They are related but serve different purposes.
