Control Ledger
Real-Time Process Monitoring

When variance exceeds tolerance, the ledger triggers response. Built on Statistical Process Control principles.

Live Simulation

Adjust process parameters and watch control limits recalculate.

X-bar Chart Mathematics

UCL = μ̄ + A₂ × R̄

Upper Control Limit

LCL = μ̄ − A₂ × R̄

Lower Control Limit

A₂ = 3 / (d₂ × √n)

Control chart constant (from d₂ table)

Why This Matters

In galactic logistics, a 3-sigma excursion isn't noise—it's a supply lane fracture waiting to happen. The ledger doesn't predict; it detects early enough to respond.

Deployment Protocol

01

Select Critical Parameters

Identify CTQs (Critical-to-Quality metrics) where variance directly impacts mission success.

02

Establish Baseline

Collect Phase 1 data under stable conditions. Calculate μ₀ and σ₀.

03

Set Response Triggers

Define escalation paths for 2-sigma warnings and 3-sigma alarms.

04

Automate Monitoring

Deploy sensor network feeding real-time X-bar calculations to dashboard.
