Supply chain disruptions have become one of the most common challenges for glass distributors. While external factors—like shipping delays or material shortages—are often blamed, the root causes usually include preventable planning errors. Understanding what truly went wrong requires digging below the surface.
The Event: Spacer Bar Shortage Stalled Fabrication for Six Days
A glass distributor faced an unexpected production halt when its usual supplier for spacer bars experienced an international shipping delay. While the delay itself wasn’t within the distributor’s control, the real issue was the absence of a secondary source and no inventory buffer.
Fabrication for two large projects paused mid-cycle. Project managers had to explain the delays to clients, triggering contractual penalties.
Underlying Root Causes
Procurement relied on a sole-source supplier without redundancy.
Inventory forecasting was based on monthly average demand, ignoring project-specific spikes.
Supplier lead times were not adjusted after previous minor disruptions.
Business Impacts
Project schedule delays and associated penalty fees.
Emergency sourcing at higher prices to resume operations.
Internal confidence erosion between sales, ops, and procurement teams.
Solutions Deployed
Introduced a supplier risk index tied to demand and fulfillment volatility.
Implemented dual-sourcing mandates for all critical-path components.
Set dynamic reorder points based on rolling project-based demand.
Distributors can’t always control supply delays—but they can control their resilience. Root cause reviews that focus inward, not outward, make future disruptions manageable instead of catastrophic.
