JIT vs JIC: Choosing the Right Posture for Your Supply Risk
Just-in-time efficiency vs just-in-case resilience — segment by item criticality and supplier reliability, not ideology.
Nobody plans to throw margin away. It happens when rotation rules live in memory instead of a list everyone opens before they order. Just-in-time (JIT) minimises inventory by timing arrivals to demand; just-in-case (JIC) holds buffers against disruption. Most real operations blend both — by SKU, supplier, and channel — and adjust after shocks. The blend should reflect lead-time risk and resilience goals, not ideology alone.
Key terms in this guide: Working capital, JIT, JIC.
Knowing the rule is not the same as seeing the next risk date in one place — which is exactly what Expiry Desk tracks automatically →

Referenced signals — spot-check sources as data ages
Cash tied up
Inventory often represents 20–35%+ of total current assets for product companies — small % improvements move real cash.
Amplifies
Forecast error compounds up the supply chain (bullwhip): ordering policies and lead times inflate swings vs end demand.
8–10%
Share of global GHG emissions from food that is lost and wasted (system-wide).
When JIT works?
Reliable suppliers, short lead times, stable demand, and low cost of stock-out — classic retail replenishment for commodity SKUs.

What this means on the floor
Requires accurate signals and disciplined expedite control; otherwise JIT becomes chronic air freight.
When JIC is rational?
Single-source inputs, long lead times, regulatory risk, or seasonal spikes — buffers buy time and sleep.

How to validate this in your next stock review
Strategic inventory after disruption is a policy choice; unwinding it needs the same rigour as building it.
Rotation only works when the soonest date is visible before the truck arrives — here is how teams close that gap →
