Engineering Productivity Calculator

Calculate engineering productivity from throughput, cycle time and output metrics.

About Engineering Productivity Calculator

This DORA-inspired composite blends five signals often correlated with healthy, sustainable engineering velocity: PR throughput (25%), PR review turnaround time (20%), PR size (20%, rewarding small reviewable changes), deployment frequency (25%, mirroring DORA's own key metric), and on-call interrupt load (10%, penalizing teams whose planned work is constantly derailed). Each sub-score is normalized 0-100 against common industry reference points before weighting, and the total maps to Elite (85+), High (70+), Medium (50+) or Low (<50).

Formula

productivity_score = pr_throughput_score × 0.25 + review_time_score × 0.20 + pr_size_score × 0.20 + deploy_frequency_score × 0.25 + oncall_load_score × 0.10

pr_throughput_score
min(100, PRs_per_week / 30 × 100)
review_time_score
max(0, 100 - avg_review_hours / 48 × 100)
pr_size_score
100 if ≤200 lines, else max(0, 100 - (lines-200)/800 × 100)
deploy_frequency_score
min(100, deploys_per_week / 7 × 100)
oncall_load_score
max(0, 100 - interrupts_per_week / 20 × 100)

Assumptions and limits

  • The result is derived only from the 5 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax or fees or charges into account.
  • Figures are rounded for display to 1 decimal place, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Why does smaller PR size score higher?

Research on code review consistently shows smaller PRs get reviewed faster, more thoroughly, and ship with fewer defects than large PRs — this score treats ~200 lines or fewer as ideal and penalizes size growth beyond that as a proxy for reviewability, not raw output.

Isn't more PRs and more deploys always better?

Not unconditionally — this model caps both scores at reference points (30 PRs/week, daily deploys) considered strong-but-sustainable benchmarks, rather than rewarding unbounded throughput that could reflect low-quality, rushed work rather than genuine productivity.

Why penalize on-call interrupts in a 'productivity' score?

Frequent on-call interruptions fragment focus time and divert engineers from planned work, which is a real (if indirect) drag on delivery — including it nudges teams to treat operational load as a first-class productivity concern, not just a reliability one.

Should this replace DORA metrics reporting?

No — treat it as a complementary, easy-to-read team health signal. Formal DORA reporting (deployment frequency, lead time, change failure rate, MTTR) should still be tracked individually for deeper investigation.
