The underlying principle behind lean manufacturing is relatively simple; to continuously eliminate as much waste as possible in the manufacturing process. Reducing waste plays a significant role in maximizing profits and minimizing expenses allowing companies to become more competitive.
The lean approach focuses on capitalizing on a company’s resources to eliminate or minimize losses in effectiveness and efficiencies that would otherwise lead to stunted production. These wastes include everything from project management tools for manufacturers to employee skillset.
In lean manufacturing, waste refers to all the activities that use up resources without driving value to the end consumer. That said, only a small percentage of activities in the entire work process provides value to the customer if the industry is chock-full of waste.
From unused materials to idle workers, all of which can’t be repurposed or recycled and reduce productivity, this emphasis on consistently minimizing waste is the foundation of lean manufacturing or production. No matter what industry you’re in, Prodsmart has customizable solutions to help simplify production management and tracking.
Lean Manufacturing involves using techniques that will produce quality goods or services while cutting down on the cost of production. A more simple way to say this is that lean manufacturing encompasses production methods, which bring about thriftiness without compromising business productivity.
The term lean was first used in manufacturing by John Krafcik in an article published in the late ’80s based on his master’s in management thesis at MIT. He was a quality engineer in California at General Motors and Toyota joint venture before enrolling for his master’s degree.
Lean manufacturing or production refers to a methodology or collection of best practices designed to eliminate waste in the manufacturing process without compromising production. The goal is to remove all those unnecessary activities that don’t contribute to the customer’s perception of value.
While the concept of lean production rose to fame thanks to Toyota Production System, it can be traced back to the Poor Richard’s Almanack by Benjamin Franklin. In it, he states that eliminating unnecessary expenses in the line of production could have a much more significant impact on profit than improving sales.
After Krafcki first coined the term in 1988, David Jones and James Womack went on to define the core principles of lean manufacturing:
One of the main hindrances to building efficient and robust work processes are wasteful activities or Mudas. After careful observation, one of Toyota Production System founders, Taiichi Ohno, identified seven types of waste in lean manufacturing:
Eliminating or minimizing waste is vital to lean manufacturing, albeit there is a controversy on whom the end consumer is. For some, lean manufacturing is a methodology whose primary goal is to maximize profits, while for others, it works solely for the benefit of the end consumer.
Lean manufacturing revolves around optimizing activities and processes with the primary goal of eliminating waste. While these may seem like easy steps, they play a significant role in cutting production costs while allowing a company to maximize the quality and, subsequently, the value of products.
In lean, the focus is on improving efficiency throughout a product’s lifecycle without compromising on quality. It emphasizes making continuous improvements, i.e., taking small steps to effect sustainable changes instead of sudden drastic changes that will disrupt the current workplace systems.
Doing so ensures that the personnel working with these materials, machinery, and processes will implement the changes moving forward.
For companies to become competitive and get an edge over their competitors, they have to continuously evolve with their end customer’s dynamic needs and wants. Therefore, each of the company’s processes and activities should be developed to meet their exact requirements and expectations.
One way of doing this is through total quality management—abbreviated to TQM. It refers to a company-wide effort to drive success by doing everything necessary to improve customer satisfaction.
The key to thriving in any market is never to become complacent. On that note, TQM’s primary focus is on providing an environment for continuously improving quality.
Lean manufacturing also focuses on reducing the time it takes workers to complete each stage of the production process, i.e., collecting material, packing, shipping, etc. One way of doing this is by evaluating employee movement on the factory floor.
Some of the crucial questions here are:
This can be done by reorganizing how orders are presented, rearranging the inventory to have fast-moving items as close as possible to the shipping area, etc.; it effectively reduces the time it takes workers to fulfill an order, adds value by driving efficiencies, and helps cut costs because after all, time is money.
Eliminating waste is an integral element of lean manufacturing and has grown to become a widespread business practice for cutting costs and optimizing limited resources. Doing so provides companies with the opportunity to identify significant areas that need to be improved to boost performance.
That said, not all activities and processes in an organization add value to the end consumer; in fact, only a small percentage of the entire production process adds value. Furthermore, some activities deemed wasteful can be eliminated from the production process and are a necessity.
One example of such an activity is product testing—customers don’t want to pay for it, but without it, there’s a high chance of compromising quality.
One way for companies to save money is by reducing wasteful or unnecessary activities that take up valuable resources, labor, and time. What’s more, according to a study by LERC—Lean Enterprise Research Center, nearly 60% of activities in the manufacturing process are wasteful and don’t add value from the customer’s perspective.
Fortunately, lean manufacturing provides a unique opportunity to identify and improve upon these wasteful activities. The wide array of techniques in Lean allows companies to improve the quality of the product while simultaneously lowering the costs of production.
Moreover, as we mentioned above, overproduction is a primary type of waste and incurs considerable costs in terms of storage and warehousing fees. By helping to identify the unnecessary movement of resources, lean manufacturing also helps cut down costs for the extra machinery, space, and time.
Lean methodologies provide businesses of all types, not just the ones in manufacturing, a unique opportunity to identify and eliminate waste from their production processes. When companies focus on continuously improving quality, they’ll be able to improve customer relations and maximize profits.
