Seven Deadly Wastes
The main goal of every organization is to make maximum profit. There are many factors to be considered when thinking about how to make the biggest profit. Sales contribute to profit but they account for only a small percentage. There are other ways to increase profitability even before products are available for sale. Muda or waste reduction is one of the most practical ways to increase the profitability for any organization. Muda is a Japanese term which literally means futility; uselessness; idleness; superfluity; waste; wastage; wastefulness also known as the “seven wastes”. Taiichi Ohno, Chief Engineer of Toyota between 1948 and 1975 developed the seven deadly wastes as the center of the Toyota Production System (TPS). Toyota Production System is based on the principles of kaizen, continuous improvement and genchi genbutsu, go to source to find the facts to make correct decisions. The Toyota Production System is the precursor to what we understand today as lean manufacturing. Lean manufacturing goal is the elimination of wastes. In order to eliminate waste one must first understand what it is. In this paper I will briefly go through the seven deadly ways and provide some countermeasures for the seven deadly wastes.
When it comes to the seven wastes overproduction is said to be the leading waste. In it's most simplest terms, overproduction is the act of manufacturing or producing an item or product before it is really necessary. When it comes to manufacturing one might think that producing inventory ahead of time would save time and money but in fact the opposite is true. It is said that overproduction is deadliest of the seven deadly wastes because it contributes or recreates a ripple effect on to th...

... to first recognize that waste is occurring and then be able to locate the source of the wastefulness. However, lean manufacturing and continuous improvement are the keys to remaining competitive and optimizing returns on investment. It has been a while since the seven deadly wastes have been introduced into business culture. Recently, an eighth waste has been identified. The eighth waste is underutilization of employees according to Lean Thinking. Organizations are underutilizing their staff because they only employ them for a skill or trade inadvertently neglecting that these employees have creative brains that can also be used. These skilled tradespeople are the ones who work on the floor and are the best sources for coming up with ideas to eliminate the seven wastes. It is important to remember that customers pay for value added work and not for wastefulness.
Achieving quality of conformance involved conform to specifications that involve providing customers with a quality product at the right price which accounts for the cost of materials. In order for a company to achieve and produce a successful product that customers want and need, it is vital that quality management and lean systems play front row. Quality management helps organizations to reduce waste and inventory. “Lean is about challenging the way things are done and opening our eyes to that waste and inefficiency” (Lean Benefits - Benefits of Lean, Why Lean is Important, 2015). Within each of these concepts are important tool and techniques that organizations can use to achieve a quality product. In this paper I will discuss “cost of quality” from the quality management side and “kaizen’s” from the lean system side, while discussing how each of these concepts are implemented into my own life or
Intense global competition, rapid technological changes, advances in manufacturing and information technology and discerning customers are forcing manufacturers to optimize manufacturing process, operations, and all the possible nodes of supply chains that enable them to deliver high-quality products in a short period of time (Karim et al. 2013). The origins of lean thinking can be found on the shop-floors of Japanese manufacturers and, in particular, innovations at Toyota Motor Corporation (Shingo, 1981, 1989; Monden, 1994; Ohno, 1988). These innovations, resulting from a scarcity of resources and intense domestic competition in the Japanese market for automobiles, included the just-in-time (JIT) production system, the Kanban method of pull production, respect for employees and high levels of employee problem-solving/automated mistake proofing. This lean operations management design approach focused on the elimination of waste and excess from the tactical product flows at Toyota (the Toyota "seven wastes") and represented an alternative model to that of capital-intense mass production with its large batch
The lean principles respond to changing customer desires and also provide high quality, low cost and faster throughput times. Lean principles eliminate waste along entire value streams thus creating processes that require less human investment, time and effort to come up with products and services at far less costs and with much fewer defects compared with conventional business systems.[1]
To make up for the lack of resources, technology, and capital goods, Toyota was forced to initiate major changes in corporate culture and their supply chain, called the Toyota Production System (TPS) (Vanguard, 2016). The plan took decades to implement company-wide. Employees were given more responsibility for the entire manufacturing process. Every individual was held accountable for the product’s quality. A sense of pride was instilled in the employees from the top down. According to Jinichiro Nakane (2002), Taiichi Ohno inspired a “quest for a superior performance culture” in Toyota. Managers and laborers were taught to take pride in their work and were given the authority to fix inefficiencies and eliminate “muda”, or waste in English, as soon as it was
With the disposal of solid waste from process, manufacturing and its waste pose considerable challenges for many organizations. Since, landfilling has become limited, and with the cost of waste disposal continuing to rise, they needed alternative measures.
Creating a process is not always the answer to every organization. Organizations attempting to reduce waste may find themselves stuck trying to understand precisely where vital financial cuts need to take place. Variability can actually prevent Lean Six Sigma from working in a business environment and can sometimes impact flow in a negative way (Locher, 2007, p. 54). As demand in many organizations can be unpredictable, many employees will find the need to multitask in order to get the job done. Multitasking itself creates highly skilled employees that are required in a lean environment. Companies that employ individuals who are capable of multitasking benefit from these employees as the organization see’s a high degree of flexibility and responsiveness with a reduction in operational costs. Companies looking to cut waste in an environment where employees are already stretched thin by performing multiple duties and tasks beyond their job description could find its employees becoming even more overworked and see a larger degradation of performance due to understaffing in an effort to cut costs. These cost-cutting measures could actually do more harm than good to an organization.
In researching this problem, I found several articles that address these issues and offer solutions on how we can solve the problem. They speak to reducing waste and the economics
Without knowing the customer demand, the most serious consequence is caused by a large number of product waste. In the supply process, there is no clear division of labor and no clear target, resulting in waste of personnel, time waste, waste materials, unnecessary transportation, and excess inventory, leading to low-cost eventually.
As mentioned before lean thinking is a philosophy that aims increasing output with minimum resources by reducing waste and accepting only what really add value to the client. After analyzing TPS Womack came with five essential principles of lean thinking
Companies are continually striving to increase productivity and output of their operations. Their goal is to satisfy the customer with the exact product, quality, quantity, and price in the shortest amount of time. Lean has been originally created and defined as the process of eliminating waste. [1] Toyota along with the support a system to reduce or eliminate waste and non-value added activities from the various processes. [3] A value stream is the set of processes required to transform raw materials into finished goods that customer’s value. Mapping of the value stream aids the identification of value adding and non-value adding activities. [2] Some examples are listed below:
The Zero Waste International Alliance – an organization dedicated to spreading awareness about waste issues and promoting alternatives to landfill – defines zero waste as a goal to “guide people to emulate sustainable natural cycles, where all discarded materials are resources for others to use … [and] designing products and processes to … eliminate the volume and toxicity of waste and materials”. When resources are used to full efficiency, the economy will then
Elimination of waste in business practices is an important part of Kaizen. Waste is any activity which raises costs without adding value to a product. Waste could be time wasted while staff waits before starting their tasks; time wasted when workers move unnecessarily in the workplace; the irregular use of a machine.
The Goal of any business is to obtain maximum results in the most efficient manner while at the same time providing your customer with the quality product they desire. Often times this process is made difficult with waste or anything that clogs the process unnecessarily. Henry Ford aimed to eliminate this waste through looking at his manufacturing pro...

The concept of minimizing waste impacts in terms of quantity or ill-effects, by reducing quantity of wastes, reusing the waste products with simple treatments and recycling the wastes by using it as resources to produce same or modified products is usually referred to as “3R” (Shimizu, 2006). Purchasing and using resources with care can reduce the pace of consumption of resources and further connected energy and resources. Ultimately reducing wastes in multifold streams. When long lasting goods are reused time and again, it offsets harvesting of new similar or same products. This saves fresh resources exploitation and waste generation quantity. Some waste products can be consumed as resources for production of different goods or the same product, meaning recycling the same resource. This too saves fresh resources and offsets waste generation. All in all, the 3Rs individually or collectively saves fresh resources exploitation, add value to the already exploited resources and very importantly minimizes the waste quantity and its ill effects. Waste minimization efficiency is stated to be better achieved applying 3Rs in a hierarchical order; Reduce, Reuse and Recycle (Shimizu, 2006).
