The Charger ART plans in ten-week increments; a mold takes fourteen weeks and a ramp
five more. The two work systems that hold those lead times — Supply Chain and
Manufacturing — are not at PI planning and have no place on the ART board. The missed
objectives are not an execution problem of HW Base: the train commits to dates its
planning horizon cannot see, and the plant learns about releases when they are already
released.
Category: flow | Severity: warning
Observations
PI planning takes capacity, runway and certification slots as inputs — not tooling or
parts lead times (PI Planning, “What information do we need”).
Manufacturing contributes to the Portfolio, not to the train; development and
production share no FL2. The Feature Route has no edge from the plant back.
The only recurring contact is the System Demo, where Bastian Lorenz attends as a
guest — after the design is frozen.
Both molds were ordered in week 3 of the PI they were needed in; fourteen weeks cannot
fit into the seven that remain.
Suggested Actions
Plan tooling and long-lead parts one PI ahead of the features that need them.
Bring Supply Chain and the plant into PI planning as participants.
Give ramp status a path back into the train before the release, not after.
