DSM — EV Vehicle Programme
Fifteen engineering activities of an EV programme carrying 39 dependency marks, computing that the plan's workstream ordering leaves 7 rework loops and that resequencing cuts them to 3, quarantined in three iteration blocks: battery/powertrain/thermal, body/closures/crash and the software–homologation–tooling–pilot tail.
