Enterprise Software in Munich, Germany

Automotive / Manufacturing / Enterprise Software / Munich

A Munich-based automotive tier-1 supplier (EUR 2.8B annual revenue, 14,000 employees, manufacturing braking systems, chassis components, and advanced driver assistance systems across 22 plants in Germany, Eastern Europe, China, and Mexico, supplying all major European and Asian OEMs — BMW, Mercedes, VW Group, Hyundai, Toyota) needed an enterprise platform to transform supplier quality management from a reactive paper-based process to a proactive digital system. The company had grown through acquisition and organic expansion, but supplier quality management hadn't scaled proportionally. Core challenges: (1) Supplier quality tracking fragmentation — 3,200 active suppliers providing 28,000 purchased components, with quality data scattered across: SAP QM (Quality Management) module for incoming inspection results, Excel spreadsheets for supplier audit records (maintained by 45 SQEs — Supplier Quality Engineers — each with their own format), email chains for 8D corrective action management, and paper files for PPAP (Production Part Approval Process) documentation. No unified supplier quality scorecard — the VP of Quality unable to answer "who are our worst-performing suppliers?" without a 2-week data collection effort. Customer quality requirements (OEM scorecards from BMW, Mercedes, VW) requiring the company to demonstrate supplier management capability — the current fragmented approach creating audit findings and threatening preferred supplier status. (2) 8D/Corrective action chaos — 2,400 supplier quality issues annually requiring formal corrective action (8D methodology: Discipline 1-8 problem-solving process standard in automotive). 8D reports managed through email: SQE sending issue notification to supplier, supplier responding with containment action, SQE reviewing, requesting root cause analysis, supplier responding — the entire dialogue in an email thread that averaged 45 messages per 8D case. Average 8D closure time: 68 business days (versus the 30-day target most OEMs require). 340 overdue 8Ds at any point — each representing an unresolved quality risk in the supply chain. When OEM customers (particularly German OEMs) audited the company's supplier management, the inability to demonstrate timely 8D resolution was the number-one finding. (3) PPAP documentation — automotive PPAP requiring 18 elements of documentation (control plan, FMEA, dimensional results, material certifications, etc.) for every new or changed part before production approval. 4,200 active PPAPs — each a physical or PDF package maintained in a combination of shared drives, email attachments, and paper files. When a customer requested a specific PPAP element (common during quality audits), retrieval averaged 2.5 hours — sometimes the document was never found. IATF 16949 audit: the certification body flagging PPAP document control as a major nonconformity — putting the company's IATF certification (required by all OEM customers) at risk. (4) Incoming inspection bottleneck — SAP QM handling incoming inspection but lacking intelligence. Every delivered lot inspected per a fixed sampling plan — regardless of supplier quality history. The inspection team (28 technicians across Munich and satellite plants) spending equal time inspecting parts from suppliers with 99.8% quality history and suppliers with 92% quality history. Inspection throughput: 380 lots/day across all plants, with a backlog of 120+ lots during peak periods — causing production line stoppages when inspected material wasn't available in time. OEMs pushing the industry toward risk-based inspection (skip-lot, reduced inspection for proven suppliers) — the company's SAP QM configuration not supporting this without extensive customisation. (5) Betriebsrat concerns — the works council at the Munich plant concerned that a supplier quality platform might be used to monitor SQE performance (how many 8Ds they manage, resolution speed) in a way that constitutes employee surveillance. German works council law giving Betriebsrat co-determination rights over any technology that could monitor employee behaviour. Previous technology projects delayed 6-12 months by Betriebsrat objections — the company wanting to avoid a repeat.

We built an integrated supplier quality platform over 16 weeks — connecting SAP QM with structured quality workflows while addressing Betriebsrat requirements. (1) Unified supplier scorecard: aggregating quality data from all sources into a single supplier score. Data integration: SAP QM inspection results (PPM — parts per million defect rates), 8D corrective action performance (timeliness, effectiveness), PPAP approval status, audit results, and delivery performance — all feeding into a weighted supplier scorecard. Scorecard methodology: IATF 16949-aligned scoring — Quality (40%, from inspection PPM and customer complaint data), Delivery (25%, from SAP MM delivery performance), Corrective Action (20%, from 8D closure timeliness and recurrence rate), and System (15%, from audit results and PPAP compliance). Automatic calculation: scores updated in real-time as new data arrives — the VP of Quality seeing current supplier performance on a dashboard without requesting reports. Trend analysis: 12-month trending showing improvement or deterioration — enabling proactive intervention before quality issues reach OEM customers. Supplier segmentation: automatic classification into Preferred/Approved/Conditional/Phase-Out based on scorecard thresholds — with escalation workflows for suppliers entering Conditional status. (2) Digitaler 8D-Prozess (digital 8D process): structured workflow replacing email-based 8D management. Issue notification: SQE creating a quality issue in the platform — pre-populated from SAP QM inspection data (defect type, lot number, quantity affected). Supplier notification through the platform (email + portal access for the supplier's quality contact). 8D workflow: each discipline (D1-D8) as a workflow step with: defined deliverables (D3: interim containment with evidence, D4: root cause analysis with 5-Why/Ishikawa, D5: permanent corrective action with implementation plan, D6: verification evidence, D7: preventive action, D8: recognition), timeline targets (D3 within 48 hours, D4 within 10 business days, full 8D within 30 business days), and automatic escalation (overdue steps escalated to supplier management and internal category manager). Supplier portal: suppliers accessing their 8Ds through a portal — submitting responses, uploading evidence, and seeing all open issues. Reducing the email back-and-forth from 45 messages average to structured portal submissions. Effectiveness tracking: D6 verification — platform tracking whether the same defect type recurs within 6 months. If recurrence detected, the 8D is automatically reopened with a "Repeat Issue" flag — triggering senior management review. (3) PPAP digital archive: all 18 PPAP elements managed digitally with controlled access. PPAP workflow: new/changed parts triggering a PPAP workflow — the platform generating a PPAP checklist based on the submission level (Level 1-5) and tracking each element through: supplier submission, SQE review, and approval/rejection. Document management: each PPAP element stored with: version control, approval signature (digital), and link to the part number in SAP — making any PPAP element retrievable in under 30 seconds. IATF 16949 compliance: the platform serving as the PPAP document control system — satisfying the IATF requirement for controlled documentation with evidence of review and approval. Expiration management: PPAP approvals with validity periods — the platform flagging expirations and triggering re-approval workflows before engineering or process changes invalidate current approvals. (4) Risk-based incoming inspection: intelligent inspection planning replacing fixed sampling. Supplier quality history: inspection plans adjusted automatically based on supplier scorecard and historical PPM. High-performing suppliers (PPM < 50, scorecard > 90): skip-lot inspection (every 5th lot), with immediate reversion to full inspection if a defect is found. Standard suppliers: normal AQL sampling per current SAP QM plans. Low-performing suppliers: tightened inspection (100% for critical characteristics). SAP QM integration: inspection plan modifications written back to SAP QM through BAPI — the inspection floor receiving modified plans through their existing SAP QM interface, no new tool to learn. Impact: inspection workload reduced 34% while maintaining (and improving) outgoing quality — the 28 technicians handling peak demand without backlog. Production line stoppages due to inspection delay: eliminated. (5) Betriebsrat-kompatibles Design (works council-compatible design): platform designed with Betriebsrat requirements from day one. No individual SQE performance tracking: the platform does not measure or display individual SQE metrics (8Ds per person, resolution speed per engineer). Supplier quality is tracked; employee performance is not. Anonymised analytics: management reports show team-level metrics (total open 8Ds, average resolution time) but not individual attribution — Betriebsrat verifying this through platform access. Transparency: Betriebsrat members given read-only dashboard access — they can see what data the platform collects and verify that no individual employee surveillance occurs. BV agreement: a formal Betriebsvereinbarung (works agreement) signed before platform go-live — documenting what data is collected, what is not collected, and how data is used. The Betriebsrat approving the platform within 4 weeks — the fastest technology approval in the company's recent history.
