72-577: Originally called " just-in-time production ", it builds on the approach created by the founder of Toyota, Sakichi Toyoda , his son Kiichiro Toyoda , and the engineer Taiichi Ohno . The principles underlying the TPS are embodied in The Toyota Way . The main objectives of the TPS are to design out overburden ( muri ) and inconsistency ( mura ), and to eliminate waste ( muda ). The most significant effects on process value delivery are achieved by designing

144-511: A "store shelf" (the inventory storage point) for the particular part and "buy" (withdraw) the quantity it needed, and the "shelf" would be "restocked" by the work-center that produced the part, making only enough to replace the inventory that had been withdrawn. While low inventory levels are a key outcome of the System, an important element of the philosophy behind its system is to work intelligently and eliminate waste so that only minimal inventory

216-614: A $ 30 million grant from the Carnegie Corporation , which was made possible through a donation by New York City mayor Michael Bloomberg . In 2011 Food Bank was listed on Forbes magazine 200 Largest Charities list. In 2014 Food Bank was inducted into the Feeding Americas 2014 Advocacy Hall of Fame . In 2015 The Food Research & Action Center (FRAC) awarded Food Bank-chaired NYC Task Force with its Innovative Anti-Hunger Work award. In 2016 Food Bank

288-484: A 'how-to' approach. The booklet is not a manual. Rather it is an overview of the concepts, that underlie our production system. It is a reminder that lasting gains in productivity and quality are possible whenever and wherever management and employees are united in a commitment to positive change". TPS is grounded on two main conceptual pillars: Toyota has developed various tools to transfer these concepts into practice and apply them to specific requirements and conditions in

360-447: A case-study book on just-in-time in the U.S. was able to devote a full chapter to ZIPS at Omark, along with two chapters on just-in-time at several Hewlett-Packard plants, and single chapters for Harley-Davidson , John Deere, IBM-Raleigh, North Carolina, and California-based Apple Inc. , a Toyota truck-bed plant, and New United Motor Manufacturing joint venture between Toyota and General Motors . Two similar, contemporaneous books from

432-469: A commitment to continuous improvement ), and reduction of "wastes" for the producer and supplier of goods. Lean manufacturing adopts the just-in-time approach and additionally focuses on reducing cycle , flow, and throughput times by further eliminating activities that do not add any value for the customer. Lean manufacturing also involves people who work outside of the manufacturing process, such as in marketing and customer service. Lean manufacturing

504-780: A food distribution center, and waiting times in a food pantry. Toyota announced on June 29, 2011 the launch of a national program to donate its Toyota Production System expertise towards nonprofit organizations with goal of improving their operations, extending their reach, and increasing their impact. By September, less than three months later, SBP , a disaster relief organization based out of New Orleans, reported that their home rebuilds had been reduced from 12 to 18 weeks, to 6 weeks. Additionally, employing Toyota methods (like kaizen ) had reduced construction errors by 50 percent. The company included SBP among its first 20 community organizations, along with AmeriCorps. Taiichi Ohno's Workplace Management (2007) outlines in 38 chapters how to implement

576-503: A manufacturer-to-retailer model developed in the U.S. in the 1980s, referred to as quick response , has morphed over time to what is called fast fashion . The strategic elements of lean can be quite complex, and comprise multiple elements. Four different notions of lean have been identified: The other way to avoid market risk and control the supply efficiently is to cut down in stock. P&G has completed their goal to co-operate with Walmart and other wholesales companies by building

648-748: A natural consequence, a system-wide perspective rather focusing directly upon the wasteful practices themselves. Takt time is the rate at which products need to be produced to meet customer demand. The JIT system is designed to produce products at the rate of takt time, which ensures that products are produced just in time to meet customer demand. Sepheri provides a list of methodologies of just-in-time manufacturing that "are important but not exhaustive": Womack and Jones define Lean as "...a way to do more and more with less and less—less human effort, less equipment, less time, and less space—while coming closer and closer to providing customers exactly what they want" and then translate this into five key principles: Lean

720-411: A perceived clash between the new just-in-time regime and manufacturing resource planning (MRP II), a computer software-based system of manufacturing planning and control which had become prominent in industry in the 1960s and 1970s. Debates in professional meetings on just-in-time vs. MRP II were followed by published articles, one of them titled, "The Rise and Fall of Just-in-Time". Less confrontational

792-497: A prevalent practice in public healthcare, commonly known as lean healthcare. Due to the intensively competitive environment, lean approach becomes a growing alternative in the healthcare sector to achieve optimized resource management and performance improvement. According to Williams, it becomes necessary to find suppliers that are close by or can supply materials quickly with limited advance notice. When ordering small quantities of materials, suppliers' minimum order policies may pose

864-459: A problem, though. Employees are at risk of precarious work when employed by factories that utilize just-in-time and flexible production techniques. A longitudinal study of US workers since 1970 indicates employers seeking to easily adjust their workforce in response to supply and demand conditions respond by creating more nonstandard work arrangements, such as contracting and temporary work. Natural and human-made disasters will disrupt

936-403: A process capable of delivering the required results smoothly; by designing out "mura" (inconsistency). It is also crucial to ensure that the process is as flexible as necessary without stress or "muri" (overburden) since this generates "muda" (waste). Finally the tactical improvements of waste reduction or the elimination of muda are very valuable. There are eight kinds of muda that are addressed in

1008-489: A series of small improvements incrementally along the supply chain can bring forth enhanced productivity. Alternative terms for JIT manufacturing have been used. Motorola 's choice was short-cycle manufacturing (SCM). IBM 's was continuous-flow manufacturing (CFM), and demand-flow manufacturing (DFM), a term handed down from consultant John Constanza at his Institute of Technology in Colorado. Still another alternative

1080-633: A staff of over 100 full-time employees and is governed by a voluntary Board of Directors . Food Bank is a certified member of Feeding America and the New York State Food Bank Association . In July 2007, the Food Bank acquired FoodChange, Inc . Founded on research showing that approximately two million New Yorkers are at risk of hunger and that more than half of city households with children would not be able to afford food for their families within three months of

1152-495: A weekend in 1998, eliminated buffer inventories, reducing inventory from 47 days to 5 days, flow time from 15 days to 2 days, with 60% of purchased parts arriving JIT and 77% going dock to line, and suppliers reduced from 480 to 165. Hewlett-Packard, one of western industry's earliest JIT implementers, provides a set of four case studies from four H-P divisions during the mid-1980s. The four divisions, Greeley, Fort Collins, Computer Systems, and Vancouver, employed some but not all of

1224-523: Is founded on the concept of continuous and incremental improvements on product and process while eliminating redundant activities. "The value of adding activities are simply only those things the customer is willing to pay for, everything else is waste, and should be eliminated, simplified, reduced, or integrated". On principle 2, waste, see seven basic waste types under The Toyota Way . Additional waste types are: One paper suggests that an organization implementing Lean needs its own Lean plan as developed by

1296-429: Is more to just-in-time than its usual manufacturing-centered explication. Inasmuch as manufacturing ends with order-fulfillment to distributors, retailers, and end users, and also includes remanufacturing, repair, and warranty claims, just-in-time's concepts and methods have application downstream from manufacturing itself. A 1993 book on "world-class distribution logistics" discusses kanban links from factories onward, and

1368-495: Is needed. Many Western businesses, having observed Toyota's factories, set out to attack high inventory levels directly without understanding what made these reductions possible. The act of imitating without understanding the underlying concept or motivation may have led to the failure of those projects. The underlying principles, called the Toyota Way, have been outlined by Toyota as follows: External observers have summarized

1440-700: Is particularly related to the operational model implemented in the post-war 1950s and 1960s by the Japanese automobile company Toyota called the Toyota Production System (TPS), known in the United States as " The Toyota Way ". Toyota's system was erected on the two pillars of just-in-time inventory management and automated quality control. The seven "wastes" ( muda in Japanese), first formulated by Toyota engineer Shigeo Shingo, are

1512-404: Is the largest anti-hunger network in the United States, providing "food and services responsible for 72.5 million meals a year". According to the 2017 Annual Report, Food Bank has provides 1.3 billion needed meals since its foundation in 1983. In 2005 and 2006, the Food Bank received a four-star rating from Charity Navigator , the largest charity evaluator in the United States. The Food Bank

1584-475: The "Lean Leadership". This should enable Lean teams to provide suggestions for their managers who then makes the actual decisions about what to implement. Coaching is recommended when an organization starts off with Lean to impart knowledge and skills to shop-floor staff. Improvement metrics are required for informed decision-making. Lean philosophy and culture is as important as tools and methodologies. Management should not decide on solutions without understanding

1656-491: The 1980s and beyond. An article in a 1984 issue of Inc . magazine relates how Omark Industries (chain saws, ammunition, log loaders, etc.) emerged as an extensive just-in-time implementer under its US home-grown name ZIPS (zero inventory production system). At Omark's mother plant in Portland, Oregon , after the work force had received 40 hours of ZIPS training, they were "turned loose" and things began to happen. A first step

1728-542: The 1990s. Because of interest in the program from other organizations, Toyota began offering instruction in the methodology to others. Toyota has even "donated" its system to charities, providing its engineering staff and techniques to non-profits in an effort to increase their efficiency and thus ability to serve people. For example, Toyota assisted the Food Bank For New York City to significantly decrease waiting times at soup kitchens, packing times at

1800-599: The Japanese "leaned out" their processes. "They built smaller factories ... in which the only materials housed in the factory were those on which work was currently being done. In this way, inventory levels were kept low, investment in in-process inventories was at a minimum, and the investment in purchased natural resources was quickly turned around so that additional materials were purchased." Plenert goes on to explain Toyota's key role in developing this lean or just-in-time production methodology. American industrialists recognized

1872-530: The TPS. Some important concepts are: Just-in-time manufacturing Lean manufacturing is a method of manufacturing goods aimed primarily at reducing times within the production system as well as response times from suppliers and customers . It is closely related to another concept called just-in-time manufacturing (JIT manufacturing in short). Just-in-time manufacturing tries to match production to demand by only supplying goods that have been ordered and focus on efficiency, productivity (with

1944-492: The TPS: Toyota Motor Corporation published an official description of TPS for the first time in 1992; this booklet was revised in 1998. In the foreword it was said: "The TPS is a framework for conserving resources by eliminating waste. People who participate in the system learn to identify expenditures of material, effort and time that do not generate value for customers and furthermore we have avoided

2016-493: The U.S.-backed Reconstruction and Occupation of Japan following WWII. During this time, an American economist, W. Edwards Deming , and an American statistician, Walter A. Shewhart , had developed some of the earliest modern manufacturing methods and management philosophies. The two experts in their fields were the first to apply newly developed statistical models to improve efficiencies during WWII in defense industry manufacturing. At this time, however, US manufacturers outside of

2088-664: The UK are more international in scope. One of the books, with both conceptual articles and case studies, includes three sections on just-in-time practices: in Japan (e.g., at Toyota, Mazda, and Tokagawa Electric); in Europe (jmg Bostrom, Lucas Electric, Cummins Engine, IBM, 3M, Datasolve Ltd., Renault, Massey Ferguson); and in the US and Australia (Repco Manufacturing-Australia, Xerox Computer, and two on Hewlett-Packard). The second book, reporting on what

2160-416: The article, risks with implementing Lean can be reduced by: "developing a well-trained, flexible workforce, product designs that are easy to build with high quality, and a supportive, high-performance supplier network" (page 51). Three more books which include just-in-time implementations were published in 1993, 1995, and 1996, which are start-up years of the lean manufacturing/lean management movement that

2232-438: The benefits can be nullified by minor delays in the supply chain. It may also impact negatively on workers due to added stress and inflexible conditions. A successful operation depends on a company having regular outputs, high-quality processes, and reliable suppliers. Frederick Taylor and Henry Ford documented their observations relating to these topics, and Shigeo Shingo and Taiichi Ohno applied their enhanced thoughts on

2304-547: The best manufacturers in the world the Deming Prize . In addition to Deming's critical influence, Japanese companies were in a position where they needed an immediate solution to the extreme situation they were living in after World War II. American supply chain specialist Gerhard Plenert has offered four quite vague reasons, paraphrased here. During Japan's post–World War II rebuilding (of economy, infrastructure, industry, political, and social-emotional stability): Thus,

2376-399: The commonality of the two terms, Toyota production system (TPS) has been and is widely used as a synonym for both JIT and lean manufacturing. Objectives and benefits of JIT manufacturing may be stated in two primary ways: first, in specific and quantitative terms, via published case studies; second, general listings and discussion. A case-study summary from Daman Products in 1999 lists

2448-460: The company and business. Toyota has long been recognized as a leader in the automotive manufacturing and production industry. Toyota received their inspiration for the system, not from the American automotive industry (at that time the world's largest by far), but from visiting a supermarket. The idea of just-in-time production was originated by Kiichiro Toyoda , founder of Toyota. The question

2520-402: The company that are not essential to the company's short-term productivity but are nevertheless important to the company's legacy. Lean also over-focuses on the present, which hinders a company's plans for the future. Food Bank For New York City Food Bank For New York City is a non-profit social services organization and the major hunger-relief organization working against hunger in

2592-629: The defense industry were slow to accept these radical methods. Deming was later assigned to participate in the Reconstruction of Japan by General Douglas MacArthur as a manufacturing consultant. Unlike his experiences in the US, Deming found the Japanese to be very accepting of these new efficiency methods. Many of today's Lean Manufacturing methods introduced by Deming and later innovated in Japan are what we now call Lean Manufacturing. Japanese manufacturers still recognize Deming for his contributions to modern Japanese efficiency practices by awarding

2664-597: The disaster the worse the effect on just-in-time failures. Electrical power is the ultimate example of just-in-time delivery. A severe geomagnetic storm could disrupt electrical power delivery for hours to years, locally or even globally. Lack of supplies on hand to repair the electrical system would have catastrophic effects. The COVID-19 pandemic has caused disruption in JIT practices, with various quarantine restrictions on international trade and commercial activity in general interrupting supply while lacking stockpiles to handle

2736-499: The disruption; along with increased demand for medical supplies like personal protective equipment (PPE) and ventilators, and even panic buying , including of various domestically manufactured (and so less vulnerable) products like panic buying of toilet paper , disturbing regular demand. This has led to suggestions that stockpiles and diversification of suppliers should be more heavily focused. Critics of Lean argue that this management method has significant drawbacks, especially for

Lean management is nowadays implemented also in non-manufacturing processes and administrative processes. In non-manufacturing processes is still huge potential for optimization and efficiency increase. Some people have advocated using STEM resources to teach children Lean thinking instead of computer science. Lean manufacturing methodology has become

2880-409: The employees of companies operating under Lean. Common criticism of Lean is that it fails to take into consideration the employee's safety and well-being. Lean manufacturing is associated with an increased level of stress among employees, who have a small margin of error in their work environment which require perfection. Lean also over-focuses on cutting waste, which may lead management to cut sectors of

2952-573: The five boroughs. Its aim is to organize food, information and support for needy citizens of New York City. The Food Bank For New York City was founded in 1983. It has a network of approximately 1,200 emergency and community food providers, including soup kitchens , food pantries, shelters , low-income day care centers, as well as senior, youth and rehabilitation centers. Food Bank helps to provide approximately 400,000 free meals daily. Since its inception, it has collected, warehoused and distributed more than 744 million pounds of food. Food Bank has

3024-451: The flow of energy, goods and services. The down-stream customers of those goods and services will, in turn, not be able to produce their product or render their service because they were counting on incoming deliveries "just in time" and so have little or no inventory to work with. The disruption to the economic system will cascade to some degree depending on the nature and severity of the original disaster and may create shortages . The larger

This was achieved via four focused (cellular) factories, pull scheduling, kanban, visual management, and employee empowerment. Another study from NCR (Dundee, Scotland) in 1998, a producer of make-to-order automated teller machines, includes some of the same benefits while also focusing on JIT purchasing: In switching to JIT over

3168-451: The idea of lean hospital , a concept that prioritizes the patient, thus increasing the employee commitment and motivation, as well as boosting medical quality and cost effectiveness. Lean principles also have applications to software development and maintenance as well as other sectors of information technology (IT). More generally, the use of lean in information technology has become known as Lean IT . Lean methods are also applicable to

In addition, Food Bank runs Kid's Café , an after-school program providing free meals to children. According to the organization's 2013 Annual Report, Food Bank

3312-562: The method), the waste of waiting (inactive working periods due to job queues), and the waste of making defective products (reworking to fix avoidable defects in products and processes). The term Lean was coined in 1988 by American businessman John Krafcik in his article "Triumph of the Lean Production System," and defined in 1996 by American researchers James Womack and Daniel Jones to consist of five key principles: "Precisely specify value by specific product, identify

3384-424: The methodology as the "Ohno system", after Taiichi Ohno , who was instrumental in its development within Toyota. The other article, by Toyota authors in an international journal, provided additional details. Finally, those and other publicity were translated into implementations, beginning in 1980 and then quickly multiplying throughout industry in the United States and other developed countries. A seminal 1980 event

3456-654: The notion of "pull" (or "build-to-order" rather than target-driven "push") came to underpin production scheduling. Just-in-time manufacturing was introduced in Australia in the 1950s by the British Motor Corporation (Australia) at its Victoria Park plant in Sydney, from where the idea later migrated to Toyota. News about just-in-time/Toyota production system reached other western countries from Japan in 1977 in two English-language articles: one referred to

3528-421: The postwar economy of Japan were low; as a result, the focus of mass production on lowest cost per item via economies of scale had little application. Having visited and seen supermarkets in the United States, Ohno recognized that the scheduling of work should not be driven by sales or production targets but by actual sales. Given the financial situation during this period, over-production had to be avoided, and thus

3600-477: The practice of problem-solving. This going back to basics, exposing the real significance of problems and then making fundamental improvements, can be witnessed throughout the Toyota Production System. The principles of the Toyota Production System have been compared to production methods in the industrialization of construction. Toyota originally began sharing TPS with its parts suppliers in

3672-507: The principles of the Toyota Way as: What this means is that it is a system for thorough waste elimination. Here, waste refers to anything which does not advance the process, everything that does not increase added value. Many people settle for eliminating the waste that everyone recognizes as waste. But much remains that simply has not yet been recognized as waste or that people are willing to tolerate. People had resigned themselves to certain problems, had become hostage to routine and abandoned

3744-675: The products of the cheaper labor of other countries. To maintain this condition, to strengthen our control of home markets, and, above all, to broaden our opportunities in foreign markets where we must compete with the products of other industrial nations, we should welcome and encourage every influence tending to increase the efficiency of our productive processes." Continuous production improvement and incentives for such were documented in Taylor's Principles of Scientific Management (1911): Shigeo Shingo cites reading Principles of Scientific Management in 1931 and being "greatly impressed to make

3816-555: The public sector, but most results have been achieved using a much more restricted range of techniques than lean provides. The challenge in moving lean to services is the lack of widely available reference implementations to allow people to see how directly applying lean manufacturing tools and practices can work and the impact it does have. This makes it more difficult to build the level of belief seen as necessary for strong implementation. However, some research does relate widely recognized examples of success in retail and even airlines to

3888-408: The repair of poor-quality castings. Toyota engaged in intense study of each stage of the process. In 1936, when Toyota won its first truck contract with the Japanese government, the processes encountered new problems, to which Toyota responded by developing Kaizen improvement teams, which into what has become the Toyota Production System (TPS), and subsequently The Toyota Way . Levels of demand in

3960-479: The response system of stocks directly to the suppliers companies. In 1999, Spear and Bowen identified four rules which characterize the "Toyota DNA": This is a fundamentally different approach from most improvement methodologies, and requires more persistence than basic application of the tools, which may partially account for its lack of popularity. The implementation of "smooth flow" exposes quality problems that already existed, and waste reduction then happens as

4032-436: The same measures. At the time about half of H-P's 52 divisions had adopted JIT. Lean principles have been successfully applied to various sectors and services, such as call centers and healthcare. In the former, lean's waste reduction practices have been used to reduce handle time, within and between agent variation, accent barriers, as well as attain near perfect process adherence. In the latter, several hospitals have adopted

4104-407: The study and practice of scientific management his life's work". Shingo and Taiichi Ohno were key to the design of Toyota's manufacturing process. Previously a textile company, Toyota moved into building automobiles in 1934. Kiichiro Toyoda , the founder of Toyota Motor Corporation, directed the engine casting work and discovered many problems in their manufacturing, with wasted resources on

4176-575: The subject at Toyota in the late 1940s after World War II. The resulting methods were researched in the mid-20th century and dubbed Lean by John Krafcik in 1988, and then were defined in The Machine that Changed the World and further detailed by James Womack and Daniel Jones in Lean Thinking (1996). The adoption of just-in-time manufacturing in Japan can be traced back directly to

4248-514: The threat of cheap offshore labor to American workers during the 1910s and explicitly stated the goal of what is now called lean manufacturing as a countermeasure. Henry Towne, past president of the American Society of Mechanical Engineers , wrote in the foreword to Frederick Winslow Taylor's Shop Management (1911), "We are justly proud of the high wage rates which prevail throughout our country, and jealous of any interference with them by

4320-499: The true problem by consulting shop floor personnel. The solution to a specific problem for a specific company may not have generalized application. The solution must fit the problem. Value-stream mapping (VSM) and 5S are the most common approaches companies take on their first steps to Lean. Lean can be focused on specific processes, or cover the entire supply chain. Front-line workers should be involved in VSM activities. Implementing

4392-440: The underlying principles of lean. Despite this, it remains the case that the direct manufacturing examples of 'techniques' or 'tools' need to be better 'translated' into a service context to support the more prominent approaches of implementation, which has not yet received the level of work or publicity that would give starting points for implementors. The upshot of this is that each implementation often 'feels its way' along as must

4464-422: The value stream for each product, make value flow without interruptions, let customer pull value from the producer, and pursue perfection." Companies employ the strategy to increase efficiency. By receiving goods only as they need them for the production process, it reduces inventory costs and wastage, and increases productivity and profit. The downside is that it requires producers to forecast demand accurately as

4536-405: The waste of superfluous inventory of raw material and finished goods, the waste of overproduction (producing more than what is needed now), the waste of over-processing (processing or making parts beyond the standard expected by customer), the waste of transportation (unnecessary movement of people and goods inside the system), the waste of excess motion (mechanizing or automating before improving

4608-509: Was Walt Goddard's, "Kanban Versus MRP II—Which Is Best for You?" in 1982. Four years later, Goddard had answered his own question with a book advocating just-in-time. Among the best known of MRP II's advocates was George Plossl, who authored two articles questioning just-in-time's kanban planning method and the "japanning of America". But, as with Goddard, Plossl later wrote that "JIT is a concept whose time has come". Just-in-time/TPS implementations may be found in many case-study articles from

The principal speaker, Fujio Cho (later, president of Toyota Motor Corp.), in explaining the Toyota system, stirred up the audience, and led to the RMG's shifting gears from things like automation to just-in-time/Toyota production system. At least some of audience's stirring had to do with

The Food Bank was also honored with the Mighty Apple Award in 2009, 2010 and 2011. In 2007, it was among over 530 New York City arts and social service institutions to receive part of

4824-729: Was billed as the First International Conference on just-in-time manufacturing, includes case studies in three companies: Repco-Australia, IBM-UK, and 3M-UK. In addition, a day two keynote address discussed just-in-time as applied "across all disciplines, ... from accounting and systems to design and production". John Krafcik coined the term Lean in his 1988 article, "Triumph of the Lean Production System". The article states: (a) Lean manufacturing plants have higher levels of productivity/quality than non-Lean and (b) "The level of plant technology seems to have little effect on operating performance" (page 51). According to

4896-468: Was cut by 92%, productivity increased by 30%, scrap and rework ... dropped 20%, and lead time ... from order to finished product was slashed from three weeks to three days." The Inc . article states that companies using just-in-time the most extensively include "the Big Four, Hewlett-Packard , Motorola, Westinghouse Electric , General Electric , Deere & Company , and Black and Decker ". By 1986,

4968-407: Was how to implement the idea. In reading descriptions of American supermarkets, Ohno saw the supermarket as the model for what he was trying to accomplish in the factory. A customer in a supermarket takes the desired amount of goods off the shelf and purchases them. The store restocks the shelf with enough new product to fill up the shelf space. Similarly, a work-center that needed parts would go to

5040-495: Was launched in 1990 with publication of the book, The Machine That Changed the World . That one, along with other books, articles, and case studies on lean, were supplanting just-in-time terminology in the 1990s and beyond. The same period, saw the rise of books and articles with similar concepts and methodologies but with alternative names, including cycle time management , time-based competition , quick-response manufacturing , flow, and pull-based production systems . There

5112-421: Was mentioned by Goddard, who said that "Toyota Production System is often mistakenly referred to as the 'Kanban System'", and pointed out that kanban is but one element of TPS, as well as JIT production. The wide use of the term JIT manufacturing throughout the 1980s faded fast in the 1990s, as the new term lean manufacturing became established as "a more recent name for JIT". As just one testament to

After that, ZIPS spread throughout the plant's operations 'like an amoeba.'" The article also notes that Omark's 20 other plants were similarly engaged in ZIPS, beginning with pilot projects. For example, at one of Omark's smaller plants making drill bits in Mesabi, Minnesota , "large-size drill inventory
