Lean Manufacturing: Why You Should Consider It for Your Shop

February 12, 2021 3:37 pm

What do you think when you hear “lean manufacturing”? Improvement and optimization should be the first words to come to mind. Lean manufacturing does not and should not be an overwhelming transformation, and it doesn’t only apply to large companies. Big or small, transforming your manufacturing process into a lean one will help relieve headaches and increase profits. Lean manufacturing is about saving time and money, which ultimately equates to many other outlets of saving.

A Brief History of Lean Manufacturing

Without hosting a full-blown history lecture, let’s discuss the origins of the lean manufacturing philosophy.

The concept of lean manufacturing was originally introduced with Henry Ford’s assembly line. However, it was Kiichiro Toyoda who optimized Ford’s production style to develop the concept of lean manufacturing. (Hence the reference to the Toyota production system in many of the recommended books you will find below.)

If you’re interested in understanding the total influence of Toyota’s production on modern manufacturing and learning more specifically about the history of lean manufacturing, check out the book below.

Lean Manufacturing Tools

In the lean manufacturing conversation, you will often hear the word “Muda”. Muda is the Japanese word for uselessness, which describes the waste that lean manufacturing eliminates. So how is this waste eliminated? With lean tools.

There are loads of different lean tools and selecting the ones to use really depends on your business since going lean will look different from shop to shop. A couple examples of said lean tools are

  • 5S: A 5 step system that improves a poorly organized work area that would result in wasted time looking for something.
  • Bottleneck Analysis: This approach works to identify which aspect of your manufacturing process limit overall throughput and how to improve that part of the process.
  • Continuous Flow: A concept that involves minimal or no buffers between each step of the manufacturing process. Ultimately, it’s a process to eliminate any unnecessary inventory, waiting time and transport time.

Lean Manufacturing and Your Shop

So, what does it mean to go lean and why should you care? To go lean, in simple terms, means eliminating waste. Paul Akers, the modern-day father of lean, offers a great example that articulates the concept of lean very well. He explains that each and every step that is not the final product, is more or less waste. Each step that is taken to achieve the outcome must be absolutely necessary and executed in its simplest form.

Think about it. The journey to completing a machined part and delivering to your clients ’is multi-faceted. Thus, there are many points of potential waste and loss. When was the last time you broke down each step and optimized it?

Here’s the full interview with Paul Akers, who not only packages the idea of lean manufacturing in a digestible way, but removes any intimidation factor to help inspire others to implement it.

 

If you are considering going lean or simply interested in learning more about it, the best way to start, as we often say, is to read a book on the topic. However, since lean manufacturing is a trending topic, the amount of books and articles that you can find out there is can be intimidating.

Luckily, we’ve identified some of the best and most relevant books available… Here are our recommendations.

    Excuse me. Lean manufacturing in a perfect world works very well, but in the real world, it is very dangerous because you are trusting your success and profitability in others whose performance you have little or no control over. Your call. I elect to NOT put that level of critical trust in others.
