Why 30% of Your Inventory Is Not Usable and How It's Blocking Your Cash Flow

Introduction

Most manufacturing businesses do not suffer from inventory shortages. They suffer from inventory usability gaps.

In our experience across 40+ transformations, 25-35% of inventory is operationally unusable at any given time. It exists in your system. It sits in your warehouse. But it cannot support production when needed.

On paper, it looks like strength. In reality, it behaves like a cash trap.

The Misdiagnosis

Most leaders respond to inventory issues with tighter controls and system cleanups. These actions create activity, but they do not create flow.

Because the real issue is not the quantity of inventory. It is the usability of inventory at the point of need.

• Tighter procurement controls
• ERP cleanups
• Aggressive inventory reduction targets

The Business Impact

Unusable inventory silently erodes performance across multiple fronts.

A company holding ₹50 crore in inventory typically has ₹10-15 crore locked in non-moving or mismatched stock. That is idle cash with zero return.

• Working capital gets blocked in slow-moving or mismatched stock
• OTIF drops because materials exist but are not usable in time
• Procurement costs increase due to emergency buying at higher prices
• Production efficiency declines due to material uncertainty

The Gemba Inventory Usability Model™

To diagnose this, you need to look beyond stock value and understand flow.

• Availability vs Usability Gap: Material is available, but not in the right location, condition, or timing.
• Specification Mismatch: Inventory exists, but wrong grade, batch, or configuration makes it unusable.
• Flow Disruption Points: Delays between stores, production, and dispatch interrupt material movement.
• Decision Latency: Teams hesitate or delay decisions on substitution, reallocation, or liquidation.

How to Apply This on Your Shopfloor

Start with simple but powerful diagnostic questions.

Also watch for early warning signals that indicate flow failure, not planning failure.

• Can your team identify usable inventory in real time?
• How often do you purchase material that already exists internally?
• How much stock is waiting for a decision rather than movement?
• Frequent urgent purchase requests despite high stock levels
• Excess stock in one SKU and shortages in another
• Manual follow-ups required to confirm availability

Ground Reality: Where Most Leaders Miss

Your ERP system gives you visibility. It does not give you truth.

Truth exists on the shopfloor. Gemba-first thinking forces you to observe where inventory actually stops moving.

Every stoppage is a cash blockage point.

• At stores
• At inspection
• At production handoffs
• At dispatch staging

The Pattern We See Across Companies

Organizations with high inventory often still face stockouts. Organizations with tighter flow operate with less inventory and higher reliability.

Flow efficiency beats stock volume every time. Inventory is not insurance if it cannot move.

Gemba Takeaway

Inventory is not a storage problem. It is a flow problem.

Until you fix usability, you will continue to lock cash unnecessarily, miss deliveries despite having stock, and increase costs through reactive decisions.

The fastest way to unlock working capital is not reduction. It is restoring flow.
