Looking at the December 2025 KPI data, I can identify the metrics that missed their targets:

| KPI | Unit | Actual | Target | Missed Months |
|-----|------|--------|--------|---------------|
| Days sales outstanding | days | 51.2 | 45.0 | 3 |
| On-time delivery percent | pct | 0.9330 | 0.9500 | 3 |
| Active customers | count | 40 | 42 | 2 |
| Inventory turns | turns | 5.33 | 6.50 | 1 |

**Note:** Operating performance deteriorated in Q4, with DSO and on-time delivery both missing targets for three consecutive months (October–December). The DSO miss is particularly severe at 51.2 days—a 6.2-day overage suggesting cash flow pressure or collection delays heading into year-end. On-time delivery declined from Q3 performance, indicating operational constraints in fulfillment. Inventory turns fell sharply in December, likely reflecting holiday seasonality and inventory builds that didn't convert to revenue as expected.
