Total Cost of Quality
TCoQSum of preventative cost, appraisal cost, and failure cost (internal and external). Captures the total quality investment plus the cost of poor quality outcomes.
Customer Complaint Rate
Repair Accuracy Rate
Engineering Change Order Rate
ECO RateNumber of ECOs raised per period, often normalized by part count or product line. Indicator of design-stability and change-control workload.
Recall Resolution Time
Right First Time
RFTIncoming Inspection Pass Rate
Work Instruction Revision Frequency
Rate of formal updates to work instructions. Too high suggests instability or unclear standards; too low suggests obsolescence or skipped updates.
Rolled Throughput Yield
RTYProbability that a unit passes through every step of a multi-step process without rework or scrap. Product of FPY at each step. Surfaces multi-step yield loss that single-step FPY hides.
Internal Defect Rate
Preventative Cost of Quality
CoGQInvestment in prevention and appraisal: training, control plans, audits, calibration, prevention engineering. The "good" portion of TCoQ that reduces failure cost.
Uncontrolled Temporary Change Duration
Cumulative time temporary deviations or workarounds remained in production without formal MOC sign-off. Indicator of change-discipline drift.
Delivery(23 KPIs)
On-Time Delivery Rate
OTDSchedule Adherence
Manufacturing Cycle Time
Time-to-Market
TTMCapacity Utilization
Actual throughput as a percentage of theoretical maximum throughput or installed capacity. Distinct from Asset Utilization Rate, which measures asset-time use; Capacity Utilization measures output-rate use against engineered capacity.
Forecast Accuracy
Throughput Rate
Output rate measured in units per time period (units/hour, units/shift, units/day). Foundational measure of production pace. Distinct from OEE Performance Factor, which is a speed-loss ratio within available time, not an absolute output rate.
Supplier Lead Time
Supply Chain Lead Time
Stockout Rate
Order-to-Ship Cycle Time
Production Volume
Total units produced per period (shift, day, week, month). The volume measure of output, complementing rate-based metrics. Used when reporting cumulative production rather than instantaneous pace.
Takt Time
The required production rate to meet customer demand: available production time divided by customer demand units. Takt sets the throughput target. Running faster than takt builds inventory; running slower creates backlog.

Backlog Net Change
Period-over-period change in backlog. Bookings minus shipments. Positive means demand is outrunning capacity; negative means the order book is shrinking.

Days Payable Outstanding
DPOReturn on Assets
ROARevenue Growth
Conversion Waste
Material lost as part of the conversion process by design: trim, swarf, runners, risers, edge waste, sprues, kerf. Distinct from Scrap Rate, which captures defect-driven loss. Reduced through process design, material specification, and nesting / sequencing changes.
Days Sales Outstanding
DSOMaterial Variance %
Actual material consumption divided by BOM-theoretical material consumption, less one. Captures combined effect of conversion waste, defect-driven scrap, and unrecorded loss. Diagnostic tool when reconciling material accounting to physical reality.
Mix Yield Ratio
Percentage of revenue (or volume) from higher-margin SKUs versus the planned mix target. Indicator of mix-shift effectiveness, independent of overall margin compression.
Premium Freight % Sales
Premium freight cost as percentage of sales. Indicator of delivery-failure recovery cost: every dollar here usually means a planning, capacity, or supplier-reliability miss upstream.
