Your delivery data already knows the answer.
Drop a standard Jira, Linear or Azure DevOps CSV export and get cycle time percentiles, throughput trends and WIP aging in under two minutes - no login, no integration, nothing leaves your browser.
🔒
Privacy by design: the CSV is parsed and analyzed entirely client-side. Nothing is uploaded, stored remotely, or sent to any server - not even this one.

Column mapping
We auto-detected likely matches from ( rows). Confirm or adjust before analyzing.
Assignee/owner columns are intentionally never offered here - this tool measures the system, not people. See guardrails in the docs.
Date format
Status classification
Tell us which of your status values mean "in progress" vs "done" vs "not started yet" - this drives WIP and aging.

Current WIP-
Little's Law check (approximation - see assumptions)
Avg. WIP (approx.)-
Avg. throughput / week-
Predicted cycle time (WIP ÷ throughput)-
Observed mean cycle time-
Divergence-
Assumes a roughly stable system across the analyzed window. Avg. WIP is reconstructed from creation/completion dates, not measured directly - treat this as a directional signal, not a precise measurement.
Flow efficiency (approx.)
Active work time ÷ total lead time-
Based on items with a confirmed work-start date. Approximation - does not account for partial/parallel work.
Throughput for Delivery Estimator
Worst case /week-
Most likely-
Best case-
P10 / median / P90 of the weekly throughput series above - this analyzer measures the past, Estimator forecasts the future with these same numbers. Paste them straight into Estimator's "Estimation" mode fields of the same name.

Cycle time scatterplot
Each dot is one finished item (completion date × cycle days). Lines mark P50/P85/P95.
Weekly throughput series
Bars per week; line marks the median. Last 4 weeks shaded if a degradation/improvement finding is active.
Cycle time distribution
Colored by percentile band: P50 and below in green, up to P85 in blue, up to P95 in amber, beyond in red.
WIP aging table
In-progress items ordered by age, banded against historical cycle time percentiles.
