V — Calibration
| Parameter | Value |
|---|---|
| Golden-file calibration cases | |
| Tolerance bands | p-value ±0.005, Cpk ±0.05, correlation ±0.02 |
| Automated compliance checks | 28 daily, SOC 2 aligned |
| Internal standards | 25 with 400+ machine-readable assertions |
| Audit trail | Hash-chained, tamper-evident Aug 2026 |
| Public dashboard | svend.ai/compliance |
We treat our software like a calibrated instrument. If any analysis drifts outside tolerance, a DriftViolation is created before it reaches users.

VII — Questions
How much does a typical quality tool stack cost?
Minitab licences run approximately $1,800 per seat per year. Add a separate value stream mapping tool and a hoshin planning tool and the cost per quality engineer climbs well past that, before any integration work. SVEND puts SPC, capability analysis, Gage R&R, hypothesis testing, regression, reliability, value stream mapping and hoshin kanri on one bench, starting at $19/month.
How do I know the statistical results are correct?
Every statistical engine is validated against golden-file test cases with defined tolerance bands: p-values within ±0.005, Cpk within ±0.05, correlation coefficients within ±0.02. These calibration checks run daily. If any analysis drifts outside tolerance, a DriftViolation is created and the analysis is flagged before it reaches users. We maintain 25 internal standards with over 400 machine-readable assertions, and 28 automated compliance checks run daily aligned to SOC 2 controls. The live compliance dashboard at svend.ai/compliance shows current calibration status.
Is my data private?
Yes. Your process data is never used to train models, never shared across tenants, and never accessed by SVEND personnel without explicit written authorization. Sensitive fields are encrypted at rest and all traffic is encrypted in transit. Tenants are isolated at the database level by Postgres row-level security, and accounts support multi-factor authentication. A tamper-evident, hash-chained audit trail over analytical records is in build for August 2026.
What is Bayesian SPC?
Bayesian SPC applies Bayesian statistical methods to process monitoring and capability analysis. Instead of producing a single point estimate for Cpk, Bayesian SPC produces a posterior distribution—a credible interval that quantifies uncertainty. This means you can make statements like “there is a 95% probability that Cpk exceeds 1.33” rather than relying on a single number that may be unreliable with small samples. Bayesian control charts also incorporate prior knowledge about process behavior, making them more sensitive to real shifts and less prone to false alarms than traditional Shewhart charts when process history is available. SVEND supports both classical and Bayesian approaches across all SPC and capability analyses.
What is the X-matrix?
The X-matrix is the central artifact of hoshin kanri strategy deployment. It is a single-page document that correlates four quadrants: strategic objectives (what we want to achieve), annual tactics (how we will achieve it), improvement projects (specific work), and measurable targets (how we know it worked). The correlations between quadrants make cause-and-effect relationships explicit—every project must connect to a tactic, every tactic to an objective, and every target to a project. SVEND’s X-matrix is live: project status, savings, and target progress update automatically from connected improvement work, and Monte Carlo forecasting projects expected outcomes based on current trajectory.
Can I cancel anytime?
Yes. All plans are month-to-month with no long-term commitment. Cancel from your account settings and your subscription ends at the close of the current billing period. Your data remains accessible for 90 days after cancellation for export. Annual billing is available at a discount but is not required.
