II — Statistical Analysis Engine

164 statistical analyses spanning hypothesis testing, regression, ANOVA, reliability, survival analysis, time series, machine learning, and Bayesian methods. Hypothesis testing, regression and capability are calibrated against published reference datasets with defined tolerance bands; families outside that scope are computed but not externally calibrated. The Workbench is a stateless calculator: it holds no project state, so an analysis is reproducible from its dataset and its configuration alone.

Tolerance bands: p-values ±0.005, correlation coefficients ±0.02, test statistics ±0.01. Checked on every build.

III — Statistical Process Control

Classical and Bayesian control charts with automatic rule-based detection. Process capability indices with frequentist and Bayesian estimation. Measurement system analysis for validation before capability studies.

Capability indices validated within ±0.05 of reference values. Ref: AIAG SPC Manual, 2nd Ed.

IV — Measurement Systems

A gage study is planned before it is measured, so it does not fit the stateless workbench in section II and has a bench of its own. Ten parts, three appraisers, three trials, randomized — issued as a run sheet, filled in on the floor hours or weeks later, then judged whole. How the study bench works →

The bench above is available from Pro; the Device Trust System is Team. The free Gage R&R calculator needs no account and runs the same crossed ANOVA on readings you bring. Ref: AIAG MSA Manual, 4th Ed.

V — Design of Experiments

Both halves work today. Declare your factors and their real settings, choose a design, and get back a coded matrix and a randomized run sheet to carry to the line. Type the results in when they come back and the fit runs through the same engine as everything else in section II.

Available from Pro. The full design reference covers the seven families, the run-sheet contract and the boundaries. Ref: Montgomery, Design and Analysis of Experiments, 8th Ed.

VI — Lean Operations

Value stream mapping, line balancing, OEE, takt time, kanban sizing, and a set of free operations calculators. Map current state, identify waste (DOWNTIME), simulate the line as a discrete-event model, and carry kaizen bursts forward into strategy.

Free tools available at svend.ai/tools — no account required.

VII — The Vandrebok

A practitioner's book of improvement work — a running, attested record of what you have actually done, rather than a plan for what you intend. An entry arrives by promotion from a value stream map, carries the map and burst that produced it, and is measured against the map rather than against an estimate. It is an output of value stream mapping, not a peer to it: current state, future state, waste register, review, then the book. What a vandrebok is, and how it differs from hoshin kanri →

Available from Pro. There is deliberately no savings estimator and no X-matrix — value is claimed against a measure on the map, not estimated in the book.

VIII — Platform

Multi-tenant architecture with tenant isolation enforced at the database level by Postgres row-level security, statistical results calibrated against externally certified reference values, and a public record of the result.

Team collaboration is the Team tier. Everything else on this page is Free or Pro. Deep customisation — your own domain namespace, your own branding, a bespoke deployment — is a conversation, not a tier: see pricing.
