**Industry:** Manufacturing & Industrial
**Company Size:** 2,500+ employees
**Location:** Detroit, MI, USA
**Infrastructure:** On-premises data center with hybrid cloud
AutoParts Manufacturing needed to modernize their 40-year-old manufacturing facilities:
**Equipment downtime** cost $2.3M annually in lost production**Quality defects** resulted in 4.2% scrap rate (industry target: <1%)**Predictive maintenance** was reactive, not proactive**Data silos** across 12 facilities with no centralized visibility**Manual quality checks** were slow and error-proneCEO's strategic goal: Achieve Industry 4.0 leadership within 24 months. Requirements:
1. **Real-time equipment monitoring** across all production lines
2. **Predictive analytics** to prevent unplanned downtime
3. **Automated quality control** with computer vision
