| Period | Planned | Delivered | On-time | Avg delay (days) | Defects (%) | Rework (hrs) | Budget var (%) | Scope (%) | CSAT |
|---|---|---|---|---|---|---|---|---|---|
| Week 1 | 80 | 78 | 70 | 2.1 | 3.2 | 18 | +4.0 | 92 | 4.1 |
| Week 2 | 95 | 93 | 85 | 1.4 | 2.0 | 11 | +1.5 | 96 | 4.3 |
| Week 3 | 110 | 112 | 104 | 0.8 | 1.4 | 7 | -2.0 | 98 | 4.6 |
Delivery rate = Delivered ÷ Planned
On-time rate = On-time ÷ Delivered
Delay score = 1 − (Average delay ÷ 10), clamped 0–1
Time score = 0.40·Delivery rate + 0.45·On-time rate + 0.15·Delay score
Quality score = 0.70·(1 − Defect%) + 0.30·(1 − Rework hours ÷ 80)
Cost score = 1 − (|Budget variance| ÷ 25), clamped 0–1
Scope score = Scope completion% ÷ 100
Customer score = (CSAT − 1) ÷ 4
DPI (0–100) = 100 × weighted average of the five component scores. Weights are normalized so they always sum to 1.
A single index lets teams compare periods without arguing over isolated metrics. It blends volume delivered, punctuality, delay severity, and acceptance quality into one score. When the index drops, leaders can pinpoint whether the cause is late work, incomplete work, or unstable releases. Over time, the index becomes a baseline, so a move from 82 to 74 is treated as meaningful drift.
Time performance combines delivery rate, on-time rate, and average delay. For example, delivering 90 of 100 planned items yields a 0.90 delivery rate, while 72 on-time deliveries out of 90 yields 0.80 on-time rate. A two‑day average delay still earns a 0.80 delay score, keeping attention on commitments. If on-time rate falls to 0.60, the time component drops even when volume stays high, signaling planning issues.
Defects and rework hours convert directly into lost focus time. If defect rate is 4%, the defect score becomes 0.96. If rework is 20 hours, the rework score becomes 0.75 using the 80‑hour tolerance. The blended quality score rewards prevention work, code review discipline, and stable handoffs. Use this component to justify investment in testing and clear acceptance criteria because fewer defects also protect schedule.
Budget variance uses absolute variance, so both overruns and under‑spend are visible. A 5% variance earns a 0.80 cost score under the 25% tolerance. Scope completion translates progress into a 0–1 score, so partial delivery is reflected even if items shipped on time. When scope is 88%, an otherwise week cannot appear perfect, which helps align expectations with reality.
Weights normalize automatically, letting you emphasize what matters. A customer‑critical rollout might raise the customer and quality weights, while an internal tooling sprint might value time and scope. Track the index weekly, export CSV for trend sheets, and attach the PDF to status updates. Pair the score with commentary: one strength, one risk, and one action. This keeps discussions focused on outcomes and next steps.
It summarizes time, quality, cost, scope, and customer outcomes into one 0–100 score, so you can compare periods quickly and spot performance shifts.
The delay score uses a 10‑day tolerance to avoid extreme outliers dominating results. Long delays still reduce the score, but the index remains comparable across teams and months.
Yes. If delivered is higher than planned, the delivery rate is clamped at 1.00. This prevents over-delivery from hiding late work or quality problems in other components.
Start with the defaults, then adjust based on goals. For external commitments, raise time and customer weights. For reliability work, raise quality. Keep changes consistent for trend comparisons.
Yes. Use any consistent reporting window, such as sprint, week, or milestone. Consistency matters more than duration because the index compares like periods.
Check the two weakest components shown in the results. Reduce late items with better forecasting, cut defects with tests and reviews, and limit scope churn with clear acceptance criteria.
