5 KPIs Every Manufacturer Should Track (But Most Don't)
Beyond the Basics: Why Standard KPIs Aren't Enough
Most manufacturers track OEE, throughput, and scrap rates. These are important, but they tell you what happened, not why or what's coming next.
The KPIs in this guide are designed to give manufacturing leaders predictive and strategic visibility, connecting shop floor performance to financial outcomes.
KPI #1: Cost-to-Serve by Customer
What it measures: The true cost of serving each customer, including production complexity, logistics, returns, and support.
Why it matters: Revenue from a customer means nothing without understanding the cost to generate it. Many manufacturers discover that their largest customers are actually their least profitable.
- Track production costs per order (setup time, changeovers, special requirements)
- Include logistics costs (shipping, warehousing, returns)
- Factor in support costs (quality issues, complaints, special handling)
KPI #2: Schedule Adherence Rate
What it measures: The percentage of production orders completed on the originally scheduled date, without expediting or rescheduling.
Why it matters: On-time delivery is a lagging indicator. Schedule adherence tells you whether your planning process is reliable: before customers feel the impact.
- Measure at the work order level, not just shipment level
- Track root causes of schedule changes (material delays, equipment issues, priority changes)
- Benchmark by product family and production line
KPI #3: Margin Erosion Rate
What it measures: How much of your quoted/budgeted margin is lost between order confirmation and delivery, due to production inefficiencies, material cost changes, or scope creep.
Why it matters: You can have great gross margins on paper and still underperform financially. Margin erosion reveals the gap between what you planned and what you actually delivered.
KPI #4: Inventory Days by Category
What it measures: Days of inventory on hand, segmented by raw materials, WIP, and finished goods.
Why it matters: Total inventory value or turns can mask problems. Tracking by category reveals whether the issue is purchasing (raw materials), production efficiency (WIP), or demand planning (finished goods).
KPI #5: Revenue per Employee (Productive)
What it measures: Revenue generated per productive employee (excluding administrative roles), tracked over time.
Why it matters: This is one of the best indicators of operational leverage. As you grow, this number should increase: if it doesn't, you're scaling linearly rather than efficiently.
