Did anyone catch that drift before the lot shipped?

Customer shorts went from 50 a month to 12 in six months. This is how a drift gets caught before the lot ships.

  • Fill weight, lot 7731
  • 1 Auditor: hold proposed, lot 7731
  • Investigation: INV-0311 Severity 2 3 sign-offs open

A reading drifts out of spec while the line keeps running.

The lot is held in minutes, not at the next audit.

Old way

nobody sees the drift until someone reviews the chart by hand, hours or days later.

New way

the Auditor sweeps every 15 minutes and proposes the hold before the lot ships.

  • The Authority Matrix decides whether the hold can happen without waiting on a person.

Customer shorts went from 50 a month to 12 in six months.

Here's what catches it, step by step.

  1. SPC Engine

    Flags three sigma, or a run of eight, even when no one is watching.

  2. Quality (Auditor)

    Sweeps every 15 minutes and proposes the hold.

  3. Notification Center

    Tells the quality lead when the hold is proposed.

  4. Authority Matrix

    Decides whether the Auditor may hold the lot alone.

  5. Investigation Engine

    Opens the case and starts collecting evidence.
