Driver and Requirement

Answers Long-Lead Work Needs a Longer Horizon Than the PI through the decision Production Joins the Train’s Planning: the plant must start its ramp when a feature is demoed, not when the release package arrives — and the train must hear how the ramp is going while the release is still in its hands.

Who is responsible for what?

Manufacturing — starts fixtures and work instructions for a feature when it reaches Demoed; brings ramp status to every System Demo.
Manufacturing Lead — accepts a release as producible before it leaves Certified.
Production Liaison — brings ramp status to every System Demo in a standing slot.
Release Train Engineer — adds the ramp-readiness check as a standing row of the System Demo and carries blockers to the ART Sync.
System Integration — delivers production test firmware with the release candidate, not after certification.

Description

Two columns, one loop. On the Manufacturing Board, Fixtures and Instructions is entered at the demo of the feature, from the demo material and the drawings as they stand. On the Charger ART Board, a feature leaves Certified only with the plant’s producibility acceptance. With the ramp-readiness check at every System Demo, ramp status flows from the plant back into the train while the feature is still in the Release group. In force from the PI 27.1 planning on 2026-12-03.

Evaluation Criteria

Time from release date to first customer shipment under two weeks (today: five).
Every release leaves Certified with a recorded producibility acceptance.

Concerns

Fixtures started at the demo may need rework when certification forces a design change — accepted; rework on a fixture is cheaper than five weeks of waiting.

Modeling note

The ramp-readiness check is the feedback edge the Feature Route has been missing.

## Driver and Requirement

Answers [[Long-Lead Work Needs a Longer Horizon Than the PI]] through the decision
[[Production Joins the Train's Planning]]: the plant must start its ramp when a feature is
demoed, not when the release package arrives — and the train must hear how the ramp is
going while the release is still in its hands.

## Who is responsible for what?

- [[Manufacturing]] — starts fixtures and work instructions for a feature when it reaches
  `Demoed`; brings ramp status to every [[System Demo]].
- [[Manufacturing Lead]] — accepts a release as producible before it leaves `Certified`.
- [[Production Liaison]] — brings ramp status to every [[System Demo]] in a standing slot.
- [[Release Train Engineer]] — adds the ramp-readiness check as a standing row of the
  System Demo and carries blockers to the [[ART Sync]].
- [[System Integration]] — delivers production test firmware with the release candidate,
  not after certification.

## Description

Two columns, one loop. On the [[Manufacturing Board]], `Fixtures and Instructions` is
entered at the demo of the feature, from the demo material and the drawings as they
stand. On the [[Charger ART Board]], a feature leaves `Certified` only with the plant's
producibility acceptance. With the ramp-readiness check at every [[System Demo]], ramp
status flows from the plant back into the train while the feature is still in the
`Release` group. In force from the PI 27.1 planning on 2026-12-03.

## Evaluation Criteria

- Time from release date to first customer shipment under two weeks (today: five).
- Every release leaves `Certified` with a recorded producibility acceptance.

## Concerns

Fixtures started at the demo may need rework when certification forces a design change —
accepted; rework on a fixture is cheaper than five weeks of waiting.
