Guides appropriate responses to process variation using Vacanti's framework. Triggers when discussing process improvement, responding to metric changes, XmR chart signals, sprint retrospectives, or when someone asks "why did our velocity/throughput change?"

Guides Payload CMS config (payload.config.ts), collections, fields, hooks, access control, APIs. Debugs validation errors, security, relationships, queries, transactions, hook behavior.
Designs, audits, and improves analytics tracking systems using Signal Quality Index for reliable, decision-ready data in marketing, product, and growth.
Enforces A/B test setup with gates for hypothesis locking, metrics definition, sample size calculation, assumptions checks, and execution readiness before implementation.
Apply these principles when responding to variation in flow metrics.
XmR charts (Process Behaviour Charts) separate signal from noise using control limits calculated from your own data.
| What you see | What it means | What to do |
|---|---|---|
| All points within limits | Process is predictable | Improve by changing the system (reduce WIP, improve policies) |
| Point above upper limit (e.g., high cycle time) | Something exceptional happened | Investigate: what caused this specific item to take so long? |
| Point below lower limit (e.g., unusually fast) | Something exceptional happened (good!) | Investigate: what went right? Can you replicate it? |
| Run of 8 above central line | Sustained shift upward | Process has changed — investigate what shifted |
| Run of 8 below central line | Sustained shift downward | Process has improved — identify what helped |
| 3 of 4 in outer third | Early warning of potential shift | Monitor closely — may indicate emerging change |
