The Top 10 Benefits of Lean Manufacturing

Most modern-day manufacturing facilities operate at between 60% to 80% efficiency – and that gap in productivity can take a big cut out of your profit margin. If your factory is falling short of your productivity goals, it may be time to embrace Lean Manufacturing.

Lean Manufacturing empowers businesses to optimize their productivity and maximize the value of their output. Given the supply chain disruptions, labor shortages, and rising costs that impact manufacturers today, it serves as a valuable framework to help you grow a sustainable business that can adapt to significant challenges.

In this article, we’ll provide an introduction to Lean Manufacturing, and showcase the many benefits of this smart production model.

What Is Lean Manufacturing?

Lean Manufacturing is a system focused on optimizing the efficiency of the manufacturing process through the elimination of waste. At its core, Lean Manufacturing means producing more with fewer resources – whether that’s time, labor, materials, or energy.

The Toyota Motor Company first introduced the philosophy of Lean Manufacturing in 1948 as a way to improve the efficiency of its vehicular manufacturing process. In their Toyota Production Systems, the brand set out to identify seven core types of waste in manufacturing, and take steps to mitigate the impact of each one. By doing so, they were able to optimize the brand’s profitability and productivity, ensuring the company’s sustainable success over the long term.

In the ensuing decades, many other brands, large and small, have embraced the principles of Lean Manufacturing, including Ford, Nike, John Deere, and Boeing. Lean Manufacturing applies to all kinds of manufacturing businesses, and can easily be adapted to fit your company’s needs.

What is the Goal of Lean Manufacturing?

The goals of Lean Manufacturing are centered on minimizing or eliminating each of these types of waste. By optimizing production processes, schedules, and resources to reduce downtime and improve workflows, your plant will be able to enhance its productivity and improve profitability.

You’ll need to start by identifying the sources of waste in your business. “To implement the Toyota production system in your own business, there must be a total understanding of waste,” said Taiichi Ohno, the inventor of Toyota Production Systems. “Unless all sources of waste are detected and crushed, success will always be just a dream.”

Let’s review the different types of waste in Lean Manufacturing, and how you can reduce or eliminate each one in your business.

7 Types of Waste in Lean Manufacturing

Here are the 7 core types of manufacturing waste:

• Overproduction

  When plant workers produce more items than required based on current and anticipated orders, the additional inventory ties up capital and storage space. Lean Manufacturing focuses on a “just in time” model, in which production is directly in line with anticipated needs. Cut down production rates to match your business’ existing orders and anticipated demand.

• Downtime

  Downtime occurs whenever production lines come to a halt because of challenges with workers, machines, or materials, productivity rates drop significantly. Downtime costs businesses a significant amount of money. Businesses should coordinate asset management and employee scheduling to minimize unnecessary downtime.

• Transportation

  Poor layouts in manufacturing facilities lead workers to spend additional time and effort moving products from one end of the plant to another. Be strategic in the layout of your factory floors to limit transportation needs.

• Overproccessing

  In production, you shouldn’t do more work than necessary for a job. Overprocessing examples include using high-tech equipment for simple tasks or adding extra features that customers are unlikely to use.

• Inventory

  By stockpiling parts, you’re taking up valuable storage space, and assuming a risk that they may become obsolete before they’re used. Avoid hoarding excess raw materials, work-in-progress (WIP), or finished goods that will not be immediately needed.

• Motion

  Extra or awkward movements by workers – such as walking, reaching, or bending unnecessarily – consume additional energy, slow down productivity, and can lead to a higher risk of injury. Be sure to support your team with ergonomic equipment and well-designed workstations that minimize strain, reduce fatigue, and keep employees working safely and efficiently.

• Defects

  Products or parts that don’t meet quality standards will require rework or scrapping, which wastes materials and labor. By setting up strict controls to ensure products meet quality requirements at every step of production – such as stopping the line when a defect is found –  you can minimize defects and rework.
