The main difference was that those who failed copied specific practices while the successful organisations sought to understand the underlying principles required to make the whole lean system work. TPS, which was known as ‘just-in-time’ manufacturing or JIT in the 1980s, developed into lean manufacturing in the later 1980s and into the 1990s. A quality engineer called John Krafcik first coined the term lean manufacturing in his 1988 article ‘Triumph of the Lean Production System’ after working on a joint venture between Toyota and General Motors in California. By the post-war period of the later 1940s, the levels of demand in the Japanese economy were low, so Ohno determined that work schedules should be driven by actual sales rather than sales or production targets.
- This decision is linked to four distinct processing strategies that are discussed in Section 1.10.
- To capture these opportunities, each company needs to develop a detailed understanding of the most influential industry and operating-environment factors and the ability to assess tradeoffs among design choices.
- Computers and precision electronic equipment have since allowed companies to pioneer high-tech manufacturing methods.
- Working closely with other departments within the company, such as sales and marketing, to understand customer needs and develop products that meet those needs.
- It has been present since the early works published in the field of manufacturing strategy.
- This includes understanding what raw materials can be used, what equipment is needed, what conditions the good must be made under, and how the good will differentiate from competing goods.
Newer technologies also help bring new products to market faster while increasing output. Larger businesses use mechanization to mass-produce items on a much grander scale. This process involves the use of machines, which means that the manual manipulation of materials isn’t necessarily required.
One key consideration is how much value the company wants to create in the manufacturing process. Another is how much flexibility the company wants to maintain in response to changes in manufacturing volume, especially for products that are subject to large fluctuations in demand. We have identified 11 design choices that companies should assess in answering these questions. (See Exhibit 1.) Our study, including a survey of more than 1,700 executives and operations managers, confirmed that these choices are the most important ones to evaluate. Although they are universally applicable, these design choices have characteristics that are specific to each industry. As a result, the optimal outcome for the tradeoffs varies depending on the industry and on the company’s operating environment and specific priorities.
What Is A Manufacturing-Based Approach In Procurement?
A steady market signal of constant demand for product required in quantity to treat a chronic disease like rheumatoid arthritis. Perishable goods manufactured in excess of market demand have to be discounted or disposed of (which impact on profitability). Local optimum manufacturing KPIs are not adequate to identify and address these problems. Identify any specific tools or equipment necessary to build and test the product. Define the necessary processes and the necessary skills for personnel to fabricate, tool, assemble, test, and support the product.
Any improvements should also be backed up by improvement metrics and it is often best to make small incremental changes rather than large sweeping ones. The five core principles of lean manufacturing are defined as value, the value stream, flow, pull and perfection. As with all useful tools there is a specific phase for everything, but the optimization of the process often requires the use of all the relevant tools used in concert and in the correct order. This is why all other tools like Poke Yoke (mistake-proofing), and SMED (changeover), are very important sister tools that together enable successful implementation of a pull strategy for optimal process flow.
The allocation of space and activities within a plant should promote a smooth and steady flow of production material, equipment, and manpower at minimum cost. A company can choose between highly flexible setups (such as modular or flexible-cell manufacturing) and highly specialized setups (such as conventional assembly lines with a standard takt, or pace of production). For example, Audi produces its e-tron GT model using a flexible assembly process supported by an automatic guided vehicle system that carries vehicles between workstations. Because the manufacturing process is heavily reliant on raw materials, the manufacturing process often relies on heavy machinery or equipment. During production, machinery may not be required depending on the output. More efficient workflows, resource allocation, production and storage can benefit businesses regardless of size or output.
Purification resin reconditioning in between successive campaigns is a relevant example of this type of activity. Traditional KPIs are unable to drive improved responsiveness in product and customer relationship management functions. As already discussed in previous sections of this chapter, the rationale behind these two concerns is the existence of trade-offs between different aspects of manufacturing performance. It has been present since the early works published in the field of manufacturing strategy. Our diverse, global teams bring deep industry and functional expertise and a range of perspectives that question the status quo and spark change.
The strength of this approach is that it allows the customer the say in defining quality. The reason is that expectations can also be highly varied, and personal, which can be problematic. Furthermore, customers may not be in a position to articulate their expectations due to a lack of knowledge and understanding. While lean contends that waste is a product of additional steps, processes and features that a customer doesn’t believe add value, Six Sigma sees waste as a product of process variation.
Competing Strategic Objectives Demand a Comprehensive Approach
The company must also evaluate product demand and scale up (or scale down) based on consumer preference. Though many believe manufacturing only entails the physical aspect of making a good, the manufacturing process still incorporates researching the potential product to explore ways to make it better. This includes understanding what raw materials can be used, what equipment is needed, what conditions the good must be made under, and how the good will differentiate from competing goods.
Although manufacturers can consolidate the operations of several smaller factories, they should do so only within a free-trade zone in order to maintain market access. Recognizing the importance of staying close to customers while capturing cost advantages, Western European and US manufacturers have shifted some production to Eastern Europe and Mexico, respectively, in recent decades. Automotive OEMs, for example, can achieve cost advantages by buying commodity components, such as sun visors, without worrying about losing any product differentiation. For some automakers, commodity components extend to key components, such as the engine and other drive technology because many customers no longer view driving dynamics as being a differentiating factor. In the coming years, OEMs will find new strategically relevant ways to differentiate their products, such as battery systems, and these components will be strong candidates for in-house manufacturing.
Our model found these three changes, in combination, could reduce conversion costs by a total of 4% to 6%. Established companies need to rapidly improve their value proposition to stay on top in the fast-changing market environment. Product cost and quality, the technology incorporated in products, and the service level offered are important factors in determining a company’s value proposition.
A five-axis machining center requires a larger monetary investment but offers greater flexibility. The tradeoff between lead time and utilization is evident in the 3-D printing service industry. Service providers can keep their costs down by heavily utilizing a small number of printers, but this means that customers must wait longer for delivery of their printed products. Alternatively, providers can operate with enough printers to ensure short delivery times—but they must be willing to accept relatively low utilization levels per printer. For example, the study found that automakers in Western Europe were far more likely than those in China to pursue cost savings through outsourcing.
Streamlining the manufacturing process to reduce waste and improve efficiency. Focusing on quality at every stage of production, from raw materials to finished products. Building strong relationships with suppliers to ensure a steady supply of high-quality materials.
In our example, the company could reduce the percentage of indirect employees in its workforce while increasing the number of produced cars. But a company also needs to consider whether shifting to centralization or best-cost countries would increase customs and logistics costs. After taking https://www.globalcloudteam.com/ into account these factors, the model found that a zero-based approach could reduce conversion costs by a total of 4% to 6%. Lean manufacturing is a form production that can be used by manufacturers that want to reduce production system time in order to increase their efficiency.
The first team did not test its machine on synthetic grass before the competition. Its steel machine was heavy, which created large friction forces between its tank-line treads and the synthetic grass. The second team did not have time to test their steering mechanism due to last-minute modifications. As a result, it could not consistently maneuver into position for putts within the time constraint. The third team completed manufacture and testing of its moving platform 2 weeks before the final competition.
