Shortages rarely arrive without warning. Lead times stretch, distributors start limiting quantities, and prices move before parts disappear. This guide shows what to watch.
Watch the direction, not the number
A single lead-time quote tells you little. What matters is how it changes over successive weeks across several suppliers.
- Track quotes for your top-risk parts weekly
- Compare franchised and independent availability
- Note when quantity limits appear
Allocation is a late signal
By the time a manufacturer announces allocation, available stock is usually already thin. Act on earlier signals where you can.
Plan around the trend, not the last quote you received.
What to do when signals turn
Prioritize parts with single sources and long qualification cycles. Consider buffer stock, approved alternates or a supply program for those lines.
Build it into your routine
A regular review of your highest-risk line items can help identify supply constraints earlier and support timely sourcing decisions.
