Understanding Lean Manufacturing: What to Avoid to Succeed

What to Avoid in Lean Manufacturing: High Inventory Levels

If you're brushing up on your lean manufacturing knowledge—especially for that upcoming Red Seal Tool and Die Maker Exam—you've probably run across the concept of minimizing waste. It’s like that old saying: "Less is more." In manufacturing, that means avoiding hefty inventory levels. So, what’s the deal with high inventory? Let’s break it down!

High Inventory: The Red Flag of Lean Manufacturing

When it comes to lean manufacturing, high inventory levels aren’t just a no-go; they’re practically the poster child for everything lean tries to avoid. Why? Because high inventory ties up resources and increases costs without adding real value. Imagine your garage packed with items you might never use—a total waste of space, right?

In essence, high inventory can lead to:

• Increased holding costs
• Waste from expired products
• Obsolete items lingering around

Lean principles advocate for just-in-time (JIT) manufacturing, where you produce only what you need, when you need it. This approach helps streamline operations and keep costs down. Think about it: wouldn’t you rather have cash in your pocket than products sitting on a shelf?
