Umsatzverluste durch Fehlmengen und nicht erfüllte OEM-Abrufe
Definition
Automotive Kanban systems formalise JIT by tying each replenishment to actual downstream demand, with withdrawal and production Kanbans driving exact quantities and timing for parts sent to assembly plants.[5][8] OEMs typically operate strict call‑off schedules and impose contractual penalties or reduce future allocations if suppliers fail to deliver JIT quantities on time. While public Australian case data is scarce, global automotive sourcing practice suggests that suppliers can face chargebacks (e.g. per late delivery), premium freight at their expense, or even loss of nominated status, equating to permanent revenue loss. If a Tier‑1/Tier‑2 supplier in Australia turns over AUD 50–150 million, even a 1–3 % impact from JIT‑related delivery failures (penalties, lost call‑offs, or lost future nomination) equals AUD 0.5–4.5 million per year. This is consistent with broader lean literature that notes JIT reduces warehousing but increases exposure to demand and supply variability.[6][8] A logic‑based range of 1–3 % of revenue is therefore realistic for plants with immature Kanban processes, especially where demand is volatile and schedules change frequently.
Key Findings
- Financial Impact: Logic-based estimate: 1–3 % of annual revenue due to JIT/Kanban‑related delivery failures. For an auto‑parts plant with AUD 50–150 million turnover, this equals ~AUD 0.5–4.5 million per year in lost sales and penalties.
- Frequency: Chronic: recurring across the year whenever schedules change quickly or internal Kanban data are inaccurate.
- Root Cause: Misalignment between OEM call‑off data and internal Kanban quantities, manual updates, poor demand forecasting, and lack of real‑time integration between production, warehouse and customer EDI signals.
