Nike obtains its finished products from manufacturing facilities located whole across the world. Nike followed a complicated supply chain system. It obtained orders from retailers Nike a leading manufacturer of shoes and other sports equipment in the world faced lots of problems in adopting new software to streamline its supply chain and manufacturing processes in order to reduce gap between its products demand and supply, six months before their dates of delivery. These orders were to be forwarded to the various factories located across the world. Finished goods obtained where then shipped to the respective retailers. In order to improve its logistics and working schedule Nike thought of implementation of supply chain but their implementations lead to sequence of failures but with strong determination Nike was able to emerge successful and now Nike is one of the topmost leading brands. This case deals with the problems faced by Nike in implementing a new software application to streamline its supply chain and manufacturing processes.

Now it can feel like fast fashion reigns supreme but plenty of love still goes into creating handmade shoes. Now, unlike the original cobblers, high quality shoes are made using a nesting manufacturing process. So, if your question is ‘how does a factory make shoes?’ this is what we are taking a closer look at. In nesting manufacturing a factory’s various departments each performs different stages of the production process. When a department has finished their role, the shoes are forwarded to the next department in line. And unlike throwaway fashion footwear bespoke shoes undergo a surprisingly high number of different stages before they are ready to be worn. Not every manufacturer is the same and the number of steps involved depends on the production methods they use. Looking for a ballpark figure? Let’s just say a shoe may be created in 70 steps – or it may take 390 1.2 Objective of Project To improve the quality of products, eliminate unnecessary waste, reduce production times, and reduce total costs. Cost reduction, including labour, Reduction in the timing of the creation of products, Reduction of production and storage space, Guarantee of product delivery to the customer, Maximum quality at a certain cost or minimum cost at a certain quality. 1 1.3 Lean Manufacturing Lean manufacturing addresses one of the worst things that can happen to any enterprise: waste. To not take full advantage of all your resources is to lose efficiencies and, in so doing, stunt production. These neglected resources include everything from manufacturing project management tools, to the skills of the staff members. Industry is, of course, rife with waste. Whether it is idle workers or unused materials that cannot be recycled or repurposed, the results are the same: a drag on productivity. This insistence on eliminating waste is where the idea of lean as a management system developed. Called lean manufacturing or lean production, the truth is that the lessons learned from this methodology can be universally applied. Lean manufacturing principles can help your business processes gain efficiencies and, as a result, become more effective and competitive in any marketplace. So, even if you are not in the manufacturing business, you can still learn something from this methodology that changed the world. Lean is a methodology to reduce waste in a manufacturing system without sacrificing productivity. The customer defines what is of value in terms of what they would pay for the product or service. Through lean management, what adds value becomes clear by removing or reducing everything that does not add value. 1.3.1 History of Lean Manufacturing The idea of lean manufacturing was first championed by the Toyota Production System and called lean in the 1990s. This coincided with the growth of Toyota from a small company to one of the world’s most successful seller of motor vehicles. But lean as an idea that encompasses reduction of waste goes back to Benjamin Franklin, who wrote about it in his Poor Richard’s Almanack. He noted that avoiding unnecessary costs could be more profitable than increasing sales. This idea, and other relevant concepts appear in his essay “The Way to Wealth.” 2 The idea grew into what mechanical engineer Frederick Winslow Taylor called scientific management, which analyses and synthesizes workflow to improve efficiencies. In his book Principles of Scientific Management, published in 1911, he codified the process. The term lean as a principle of manufacturing was first used by John Krafcik in the article “Triumph of the Lean Production System,” which was published in 1988 and based on his MIT Sloan School of Management master’s thesis. Krafcik worked as a quality engineer for a joint venture between Toyota and GM in California before he earned his master’s. 1.3.2 Princip of Lean 1. Value: Value is always defined by the customer’s needs for a specific product. For example, what is the timeline for manufacturing and delivery? What is the price point? What are other important requirements or expectations that must be met? This information is vital for defining value. 2. Value stream: Once the value (end goal) has been determined, the next step is mapping the “value stream,” or all the steps and processes involved in taking a specific product from raw materials and delivering the final product to the customer. Value-stream mapping is a simple but eye-opening experience that identifies all the actions that take a product or service through any process. That process can be in design, production, procurement, HR, administration, delivery, or customer service. The idea is to draw, on one page, a "map" of the flow of material/product through the process. The goal is to identify every step that does not create value and then find ways to eliminate those wasteful steps. Value-stream mapping is sometimes referred to as process reengineering. Ultimately this exercise also results in a better understanding of the entire business operation. 3. Flow: After the waste has been removed from the value stream, the next step is to be sure the remaining steps flow smoothly with no interruptions, delays, or bottlenecks. “Make the value-creating steps occur in tight sequence so that the product or service will flow smoothly toward the customer,” advises LEI. This may require breaking down silo thinking and making the effort to become cross-functional across all departments, which can be one of the greatest challenges for lean programs to overcome. However, 3 studies show that this will also lead to huge gains in productivity and efficiency, sometimes as high as 50-percent improvement or more. 4. Pull: With improved flow, time to market (or time to customer) can be dramatically improved. This makes it much easier to deliver products as needed, as in “just in time” manufacturing or delivery. This means the customer can “pull” the product from you as needed (often in weeks, instead of months). As a result, products don’t need to be built in advance or materials stockpiled, creating expensive inventory that needs to be managed, saving money for both the manufacturer/provider and the customer. 5. Perfection: Accomplishing Steps 1-4 is a great start, but the fifth step is perhaps the most important: making lean thinking and process improvement part of your corporate culture. As gains continue to pile up, it is important to remember lean is not a static system and requires constant effort and vigilance to perfect. Every employee should be involved in implementing lean. Lean experts often say that a process is not truly lean until it has been through value-stream mapping at least half a dozen times. Figure 1: Princip of Lean Manufacturing 4 1.4 VALUE STREAM MAPPING Value stream mapping is a flowchart method to illustrate, analyze and improve the steps required to deliver a product or service. A key part of lean methodology, VSM reviews the flow of process steps and information from origin to delivery to the customer. As with other types of flowcharts, it uses a system of symbols to depict various work activities and information flows. VSM is especially useful to find and eliminate waste. Items are mapped as adding value or not adding value from the customer’s standpoint, with the purpose of rooting out items that don’t add value. Figure 2: Example of VSM It is important to keep in mind that customers, whether external or internal, care about the value of the product or service to them, not the efforts it took to produce it, or the value that may flow to other customers. Value stream mapping maintains that focus. A typical process is to draw a current state VSM and then model a better way with a future state and/or ideal state VSM. You can start off sketching by hand and then move to VSM software for better communication, analysis, and collaboration. Value stream mapping is a powerful method to ferret out waste in any process, not just manufacturing. That is its core purpose. You detail each significant process step and evaluate how it is adding value or not adding value from the customer’s standpoint. That focus on value 5 keeps the analysis targeted to what really matters, allowing the company to compete most effectively in the market. Foreseeing or facing any competitive threat, lean practitioners can make good use of VSM to produce the most value for the customer in the most efficient way possible. It can and should be used on an ongoing basis for continuous improvement, bringing better and better process steps online. VSM allows you to see not only the waste, but the source or cause of the waste. Value stream mapping, as with other good visualizations, serves as an effective tool for communication, collaboration and even culture change. Decision makers can clearly visualize the current state of the process and where waste is occurring. They can see problems like process delays, excessive downtime, constraints, and inventory issues. And with the Future State and/or Ideal State VSM, they can see precisely how to improve. Although its typical purpose is eliminating waste, VSM can also be seen from the perspective of adding value. After all, that is what the customer cares about. Eliminating waste is the means to an end of creating value, such as a lower price and/or better-quality product or service. Value is something a customer is willing to pay for. The title of a popular VSM book is even: Learning to See: Value Stream Mapping to Add Value and Eliminate Muda, by Mike Rother and John Shook. (Muda is lean terminology for waste.) 6 CHAPTER 2 LITERATURE REVIEW This section of the report provides a brief background on the topics we researched in order to complete this project. Lean manufacturing, value stream mapping and information about the sponsoring company were relevant information we needed to consider before we began work on the project. 2.1 Project Background In this chapter we will discuss relevant background information for our project. First, we will briefly describe about Nike company. Then we will provide information about the product we worked with. Finally, we will discuss the manufacturing process and the factory layout. 2.2 Nike Nike, Inc. is an American multinational corporation that is engaged in the design, development and worldwide marketing and selling of footwear, apparel, equipment, accessories, and services. The company takes its name from Nike, the Greek goddess of victory. It is the world's leading supplier of athletic shoes and apparel and a major manufacturer of sports equipment. The brand alone is valued at $10.7 Billion making it the most valuable brand among sports businesses Nike, Inc., formerly (1964–78) Blue Ribbon Sports, American sportswear company headquartered in Beaverton, Oregon. It was founded in 1964 as BlueRibbon Sports by Bill Bowerman, a track-and-field coach at the University of Oregon, and his former student Phil Knight. They opened their first retail outlet in 1966 and launched 7 the Nike brand shoe in 1972. The company was renamed Nike, Inc., in 1978 and went public two years later. By the early 21st century, Nike had retail outlets and distributors in more than 170 countries, and its logo—a curved check mark called the “swoosh”—was recognized throughout the world. From the late 1980s Nike steadily expanded its business and diversified its product line through numerous acquisitions, including the shoe companies Cole Haan (1988; sold in 2012) and Converse, Inc. (2003), the sports-equipment producer Canstar Sports, Inc. (1994; later called Bauer and sold in 2008), and the athletic apparel and equipment company Umbro (2008; sold in 2012). In 1996 the company created Nike ACG (“all-conditions gear”), which markets products for extreme sports such as snowboarding and mountain biking. In the early 21st century Nike began selling sports-technology accessories, including portable heartrate monitors and high-altitude wrist compasses. Part of Nike’s success is owed to endorsements by such athletes as Michael Jordan, Mia Hamm, Roger Federer, and Tiger Woods. The Nike Town chain stores, the first of which opened in 1990, pay tribute to these and other company spokespersons while offering consumers a full range of Nike products. In the 1990s the company’s image briefly suffered from revelations about poor working conditions in its overseas factories. Figure 3: Map of Nike 8 Our priority is zero waste, period. Our vision is a circular future in which the very concept of waste doesn’t even exist. We are eliminating waste wherever we can, beginning by designing waste out of our products and optimizing our manufacturing processes. We know that making these key design and process shifts are critical to us achieving our goal of cutting our environmental impact in half. Waste is generated across our value chain from agricultural waste associated with harvesting raw materials to the manufacturing waste created in the process of putting the finishing touches on our products to the waste created when you’re done with our products and throw them away. For more than ten years, we’ve been designing waste out of our processes to make more efficient and more sustainable products. For us, scraps are valuable resources. We believe every ounce of material sourced to make Nike products should be put to good use. That is why we’re eliminating waste to landfill and incineration. We’re focused particularly on footwear, which accounts for nearly two-thirds of Nike manufacturing waste. We’re proud to say that today, more than half of footwear factory waste is recycled. We do this by separating waste for recycling and using waste management centres that consolidate, process and sell the scrap material to other businesses. At NIKE, we respect human rights in our operations and extended value chain, and conduct business ethically and sustainably. NIKE supports human rights as defined by the Universal Declaration of Human Rights, which recognizes that “all human beings are born free and equal in dignity and rights.” We work to elevate human potential through our products, partnerships and operations, something that cannot be accomplished without a fundamental respect for human rights throughout NIKE’s operations. We expect the same from our suppliers, and focus on working with long-term, strategic suppliers that demonstrate a commitment to engaging their workers, providing safe working conditions and advancing environmental responsibility. This includes working to combat risks of forced labor. For more information on NIKE’s commitment to sustainability and human rights, please see our annual Report. This statement is being furnished pursuant to the UK Modern Slavery Act, the Australia Commonwealth Modern Slavery Act and the California Transparency in Supply Chains Act. This statement discusses NIKE’s global business practices to address forced labour. This statement encompasses NIKE, Inc. and its consolidated subsidiaries because we take a global approach to forced labour compliance. However, not all of our consolidated subsidiaries are subject to the UK Modern Slavery Act, the Australia 9 Commonwealth Modern Slavery Act and the California Transparency in Supply Chains Act. As used in this statement, forced labour includes modern slavery, prison labour, indentured labour, bonded labour, human trafficking, or other similar conduct. Figure 4: Nike Logo Figure 5: Nike Supply Chain 10 2.3 Product (Nike Air) Their first products were track running shoes They currently also make shoes, jerseys, shorts, base layers, etc. for a wide range of sports, including track and field, baseball, ice hockey, tennis, association football (soccer), lacrosse, basketball, and cricket. Nike recently teamed up with Apple Inc. to produce the Nike+ product that monitors a runner's performance via a radio device in the shoe that links to the iPod nano. Born in Ohio in 1925, Marion Franklin Rudy (that's him, below) was an aerospace engineer, and left his career in the late ’60s to pursue creative solutions for other industries. Among his more audacious ideas: placing tiny air bags in the soles of athletic shoes to soften impact. He pitched his air-bag innovation to 23 shoe companies; all rejected him. Then, in 1977, he presented his vision to Phil Knight. The Nike co-founder took an air-cushioned prototype for a test run around the Beaverton campus, and returned to his office intrigued — Rudy’s shoe had an unprecedentedly smooth ride. Nike had found Air. Figure 6 and 7: First Design of Nike Air 11 Air, of course, is rooted in running. The first shoe to feature Air cushioning was 1978’s Tailwind, a running shoe. Before the concept of creating hype was even a thing, the Nike marketing staff decided to release a limited number of Tailwind shoes prior to a broader launch. Shoemakers at Nike’s first R&D lab in Exeter, New Hampshire, cranked out 250 pairs of the highly technical shoe, which were sent to six Hawaiian running stores for the Honolulu Marathon. The shoes sold out within 24 hours, despite an unprecedented $50 retail price. It wasn’t just hype that kept Air on runners’ feet. Also in 1978, researchers at the University of Tennessee in Knoxville asked 10 runners to run on a treadmill in the Tailwind. They found that the athletes used less energy running in the Air shoes than running in conventional running shoes. Runners and science had validated Air. What was left in the mid-’80s was to capture the attention of even more joggers. That’s when design, coupled with ample audacity, came in. Big windows. Forefoot Air. Full-length Air! Tuned Air. These were some of the astounding changes to both the make and aesthetic that put the Max in Air during the ’90s, and its evolution mirrored the tenor of the decade. The era had a new soundtrack. Hip-hop was expanding, Brit-pop dominated the charts and new iterations of dance music were speeding up BPMs and helping to welcome sportswear into raves around Europe. Streetwear was born or at least hit stride in the ’90s convergence of sport and culture. The audacious look of Air Max models, from the 90 to the Air Max Plus, helped lead a transformation in dress, each shoe equally big, bold and colourful. New technologies were also changing the way people interacted. The World Wide Web became a reality in 1991, and by the time the iMac hit in 1998, the emergent platforms (including an inventive, digitized auction service in 1995) shifted how people created communities and bought and sold goods. This digital revolution helped sneaker collecting transition from a word-of-mouth niche lifestyle to a global phenomenon. 12 Figure 8: Nike Air Max 90 While its history is rich, Air’s story is never about then. Longstanding borderline cultish crushes on specific models mean Air, in almost every iteration, is about the now. And the continual reinvention and imaginative spirit behind it means that the platform is never far from what’s next. Creating the Nike Air Max requires cooperation, camaraderie an esprit de corps. The process begins with Air Manufacturing Innovation. The folks there get to imagine possibilities the forms, feels and structures of Air and spark inspiration for future design. Their engineering breakthroughs allow other teams to unlock the keys to a softer, bouncier, more flexible ride. This launches a cascade of creativity, involving all facets of Nike's design organization colour, concept, digital, footwear, graphic, material, print, pattern and several more disciplines to drive innovation for Air Max shoes, such as the new Air Max 720. Tapping ingenuity from every discipline, and ensuring those ideas gel together, is essential for an ideal final product, says Courtney Dailey, Nike VP of Colour Design. “For example, colour needs to strike a balance between amplifying the tech and making its own statement.” The synergistic approach and unrivalled teamwork allow Nike to push new paradigms again and again. For Air, it means fresh shapes, news sensations and a continuously bold future. Most simply, Air is always at the vanguard a defining element of the zeitgeist from ’87 to infinity. 13 2.4 The Making of the Shoes 1) The Design Process -establish target price, target audience and product features -produce "tech package" to send to subcontractors in factories in Europe and Asia 2) Supplies A. Raw Materials -fabric -plastic -rubber -foams -metallics B. Textiles and Leathers 3) Cutting - In this department, the top part of the shoe or the "upper" is made. 4) Sewing (of upper section above the sole) Figure 9: Sewing Process - In this process, the upper portion is sewed into a design form. 5) Stock fitting (prepares the sole) -The sole of the shoes is prepared in this process. 14 6) Lasting (prepares attachment of upper to the sole) -The upper portion of the shoe prepared is attached to the sole of the shoe. 7) Heeling (attaches and shapes heel bottom to final form) -After the upper portion is attached to the sole of the shoe, the heel is attached to the sole and is given its final form. This process is termed as heeling 8) Finishing -Machines smooth out the excess material hanging over the insole by tucking it back in underneath the shoe. Figure 10: Finishing Process 9) Treeing (attaches accessories) -The shoelaces and accessories are put in place for the final construction of the shoe. Figure 11: Treeing Process 15 10) Distribution & Trading Companies - After the manufacturing process, the shoe is then shipped to distribution and trading companies where it is then distributed to retailers and sold to consumers. Figure 12: Stock Ready to Distribution Figure 13: Current State Map 16 TASK DESCRIPTION TASK TIME (MINUTES) IMMEDIATE PREDECESSORS A Raw Material 10 minutes - B Cutting 5 minutes A C Sewing 10 minutes B D Stock Fiting 5 minutes C E Lasting 5 minutes D F Heeling 5 minutes E G Finishing 5 minutes F H Treeing 5 minutes G I Packaging 6 minutes H Total 56 minutes 2.5 Precedence Diagram Component The precedence diagram method (PDM) is a tool for scheduling activities in a project plan. It is a method of constructing a project schedule network diagram that uses boxes, referred to as nodes, to represent activities and connects them with arrows that show the dependencies. It is also called the activity-on-node (AON) method. For examples, critical tasks, noncritical tasks, and slack time, shows the relationship of the tasks to each other and allows for what-if, worstcase, best-case and most likely scenario. 17 2.6 CYCLE TIME Cycle time includes process time, during which a unit is acted upon to bring it closer to an output, and delay time, during which a unit of work is spent waiting to take the next action. Calculate Cycle Time and Minimum Number of Workstation Cycle Time = Production Time Per Day Unit Required Per Day Cycle Time = 720 100 Cycle Time = 7.2 per min 2.7 Minimum Number of Workstation Nmin = Total Time Task (min) Cycle Time Nmin = 56 7.2 = 7.7 ~ 8 workstation We achieve our balancing with 3 workstations. 18 2.8 Factory Layout The factory layout is divided by department by department. In each department they manage by operation manager and floor manager. In the production department they divided to each section such as cutting, sewing, stock fitting, lasting, heeling, finishing, and treeing. The section was called by Line. Figure 14: Layout of the factory Figure 15: Nike Factory 19 CHAPTER 3 METHODOLOGY 3.1 PURPOSE OF METHODOLOGY The purpose of the methodology is to achieve the objective of the study. Its start from understanding the title of the study and will be end with the appropriate report. The methodology is a guideline of the study to make sure that all process follows the plan. The study will be done on the Nike shoes production that operated at the factory. The study will cover up the process flow at the Department. The problem occurs cannot be solved by applying lean tools because of the rules and policy of the company. So that, the lean tools are only be suggested for that problem. 3.2 PROBLEM IDENTIFY 3.2.1. There is a surplus of product production The problem faced by this Nike company is that over-production at a time results in a loss to the company. Nike company conducts a survey at a time to meet the needs or wants of Nike shoe enthusiasts by producing various types of shoes to ensure Nike shoe enthusiasts can choose to buy the shoes of interest. Therefore, Nike company decided to produce sketches or make shoes in a relatively short time or period between the production of shoes one and shoes two. For example, Nike company produces Nike water shoes in March starting with the lowest price of rm120 and can rise high reaching rm450 a pair and will probably be higher in price if the production of these shoes is very limited. Then the second shoe was released in May with the production of Nike running150 type shoes with prices starting from rm120 also up to rm 700. Here you will see Nike company took a relatively short time to produce one shoe model to a new model. This can lead to losses with the production of excess shoes hard shoes released in March are still for sale and promoted then new model shoes are released at the same price and quality, have not had time for shoes released in March sold out, shoes other models were released in May and this caused buyers or fans of Nike shoes to make a comparison between the old model shoes with the new model shoes that were recently released. Fans or buyers will 20 look more at the new shoes compared to the old ones; this is because with very little different quality. Next, Nike company is too much to meet the needs of buyers by producing shoes of the same model too much so as to over-production. Then these excess shoes are collected somewhere because no fan or buyer will buy this model shoes and at the end of the year Nike company will make an auction sale or called promotional sales to spend all kinds of excess shoes. In addition, Nike company is too eager to meet the needs of consumers by producing different types of shoe models. The Nike company does not focus on the best-selling types or models of shoes, this results in more shoe production on models that are not in demand or favoured by Nike shoe buyers. This Nike company also feels they are a good company among the best. This causes Nike company to make so much shoe production that over-production results in unexpected losses. Nike companies are too concerned about the name of the product causing the excess production of shoes that should be sold at a quantity of 300,000 pairs of shoes on a model and there is an artificial excess with 350,000 shoe production at a time. There is a surplus of 50,000 shoes removed resulting in the possibility of a considerable loss to the Nike company. This is not to be expected of a company when it does not take more precautionary measures when making shoe manufacturing. 3.2.2. Involved in the final inspection of the product The second is that the problems that come from the negligence of the workers cause the process of making a shoe to be chaotic and irregular. This will cause one of the unwanted things to happen that is a defect in a shoe is likely to happen. Due to the negligence of new or experienced employees will cause problems that arise. It is possible that the negligence of these employees came from a misunderstanding with each other. This needs to be taken seriously because when in a large company there must be many employees consisting of various races or races and religions. When there is no good agreement or understanding, then various issues arise from various aspects such as disrespect for each other, do not want to get to know each other or do not want to get to know the employees working in the company. This can be even bigger with the nature of the working ego and according to each case for example the installation part for own work and the stacking part for work alone, such a thing will be a problem when one part is overlooked and will cause defects in a shoe and finally on at the end of the inspection there will be a bit of a conflict i.e., the product does not last for sale due to a defect in the model. Furthermore, not enough staff or employees in the company is also one of the common 21 problems. When there are not enough staff in a company, then there are problems that occur, the shoes made are not perfect or the shoes produced cannot meet the needs of consumers. The quantity of employees or staff is also an important aspect of a company to get satisfaction or sustainability of work. Among the problems that will occur when the shortage of workers is one of them is that the work will be slow to complete, the second is that the work is likely to be a lot and will be delayed making it impossible to achieve the set targets. Work movements also become slower and the work environment is also not harmonious and very boring. This will be trivial and not taken seriously by the workers resulting in the workers working carelessly and not caring about the surrounding situation. With this also, the workers directly work without following the prescribed SOP, because working does not follow the prescribed SOP, then at some point there will be anxiety or problems that will arise such as employees will be injured, employees will be fired or not Company employees will be fined for offenses committed. Finally, the problem that caused the shoes that were made to hang on the final inspection was the lack of material. This will cause the shoes cannot be made perfectly due to lack of artificial materials. Therefore, the ingredients needed should be an important aspect to realize a product. Additives are also very important to improve a product so that it looks more stylish and easier to sell to buyers or consumers. 3.2.3 Factory layout The third problem stems from the lack of knowledge of senior staff members to form one machine position to another position. This problem will cause the arrangement of the position of the machine or the existing assets in the factory is very irregularly arranged. In other words, the position of the factory layout is very unsystematic. This is due to the relatively limited factory area. The size of the factory also plays an important role for a factory to operate well because if the factory area is relatively narrow, then the operation of the factory will probably be more disorganized with a large number of workers and an underdeveloped environment. with the capacity of the worker in line with the capacity that can be filled in the factory with the available space. Then, the quantity of machines also plays a role when stacking in a factory. If the arrangement of the machine itself is scattered, the chances of the plant not operating for a long time are quite high. If arranged in the correct position according to the position, then the work process will probably be easier and very organized. The size of a machine is also very important because if you arrange the machine with a cross or a large machine with a small 22 machine interval then the big machine will return it will likely confuse the processes in the factory to print or form a product. If the position of the machine is adjusted to the size of a machine it may be better and will be more organized. This will cause the process to run smoothly despite the relatively large and compact machine capacity. Figure 16: Current Layout 23 CHAPTER 4 RECOMMENDATION 4.1 PROBLEM SOLVING 4.1.1Kaizen The way were using kaizen concept to make more efficiently in production and make the environment safer for all workers. Kaizen concept is more like more systematic in working area to improve all condition such as reducing cycle time, reducing working space and increasing productivity. Step 1: Clarify the Problem. Step 2: Breakdown the Problem. Step 3: Set the Target. Step 4: Analyze the Root Cause. Step 5: Develop Countermeasures. Step 6: Implement Countermeasures. Step 7: Monitor Results and Process. Step 8: Standardize and Share Success. Kaizen = Continuous Improvement, Continuous Improvement means constantly searching for and implementing ways to reduce cost, improve quality and increase productivity. Small, incremental changes; break apart and put back together better, Focus on small, quick changes for long-term success, Elimination of the 8 Wastes. Kaizen is a philosophy that support continuous, incremental process changes that sustain a high level of efficiency. At one level kaizen can help personally improve the way you work by eliminating ‘waste’. At the organization level, kaizen can be a powerful team-approach that harnesses suggestion and involvement from people at every level. Wide participation can serve to improve morale and satisfaction as much as it improve production, cost and other hard measures. 24 Figure 17: Kaizen Flow Chart 4.1.2 5S The closest solution path is 5s, with this chosen path will give a new ray to the problem that occurs i.e., the product is stuck at the final inspection. 5S is a system for organizing spaces so work can be performed efficiently, effectively, and safely. This system focuses on putting everything where it belongs and keeping the workplace clean, which makes it easier for people to do their jobs without wasting time or risking injury. Sorting is the keep only necessary items in the workplace. For sort, is keep only necessary items in the workplaces. The Japanese developed the initial 5S which part of a checklist in todays. Furthermore, it also provides an easy vehicle to assist the culture change. The 5S provide a vehicle for continuous improvement with which all employees can identify. 5S stands for the 5 steps of this methodology is Sort, Set in Order, Shine, Standardize, Sustain. These steps involve going through everything in a 25 space, deciding what is necessary and what isn't, putting things in order, cleaning, and setting up procedures for performing these tasks on a regular basis. Sort: Start by removing all items from your work area. Inspect the equipment and identify those items that are critical to the success of the function performed at the workstation. Eliminate any duplicates, unnecessary equipment, infrequently used items, and trash. Identify the non-essential items as either waste or “valuable but not critical.” Store the non-critical items outside of the workstation area. This saves time, space, and labour costs, while enhancing productivity. Set in Order: Whatever equipment is deemed critical to the operation must now be organized. Assign positions for all equipment, work in progress, and raw materials, keeping ease of reach, identification, and proximity to work surface in mind as you do. The goal is to maximize the efficiency of the workstation layout. On a smaller scale, it’s the same concept as warehouse layout. The most frequently used tools should be the most convenient to grab. This eliminates wasted time from excess motion and searching. Shine: Keep everything clean, every day. Doing this keeps things ready to be used when needed. A clean workspace is a productive workspace, and Seiso literally means “to clean or shine.” Clean the floors, the walls and the equipment, and ensure all items are restored to their designated place. Make sure the workstation is well lit. This should be a part of your daily tasks and should not be postponed until idle time is available. Standardize: Ensure conditions of work area do not return to the original, disorganized state. Make the previous three S’s part of your standard procedures each day. Implement them with the help of signs, banners, shadow boards, tool holders, etc. Make sure all workers understand their responsibilities and are empowered to perform all of the tasks. Sustain: Make a habit of properly maintaining correct procedures to avoid backsliding. Implementing these steps is a continuous process. It is important to ensure that they are done each day to prevent slipping into old habits. Commit to performing these steps 26 every shift and make sure that any changes to your product or process are compensated for at your workstation and problems are alleviated as quickly as they are created. Figure 18: 5s Flow Chart 27 Figure 19: Layout After 5S 4.1.3 Jidoka Jidoka is the most appropriate way to overcome the problem experienced as the product in cannot be removed at the last time because it hangs on the inspection at the last minute. Jidoka highlights the causes of problems because work stops immediately when a problem first occurs. This leads to improvements in the processes that build in quality by eliminating the root causes of defects. Jidoka sometimes is called autonomation, meaning automation with human 28 intelligence. Jidoka is a Lean method that is widely adopted in manufacturing and product development. Also known as autonomation, it is a simple way of protecting your company from delivering products of low quality or defects to your customers while trying to keep up your takt time. The jidoka pillar is often labelled "stop and respond to every abnormality.” We can define jidoka as a four-step process that engages when abnormalities occur. 1. Detect the abnormality. 2. Stop. 3. Fix or correct the immediate condition. 4. Investigate the root cause and install a countermeasure. Many machines produced today have incorporated autonomation ideals in their design as they are seen now very much as being common sense, and with today’s technology are inexpensive and simple to incorporate into a machines design. Where we tend to fail is not having the problem highlighted but in taking action to correct the problem and solve root cause. It is important that we not only give our operators and supervisory staff the authority and responsibility to stop production when they find a problem but that we also train everyone in appropriate problem-solving tools to enable us to remove the root cause of the problem. We then need to ensure that any process documentation is updated to incorporate the changes and that we communicate those changes across similar processes and products to spread the learning. The first step of Jidoka is that of detecting an abnormality, so for autonomation the machine uses simple sensors to detect a problem and then stops and highlights the problems for the operator. For line stop the operator detects an abnormality and stops the line and highlights the problem for all to see on an andon board. Other Lean tools use various aspects of visual management to highlight abnormalities, consider 5S, we identify the locations for tools, components and work in progress, if we see things that are not in their allocated place we have seen an abnormality and should take action. 29 Figure 20: Concept Jidoka Figure 21: Jidoka 30 CHAPTER 5 CONCLUSION In this chapter of the report, first, the limitations with this research and their influences on validity and reliability of the work are discussed. Then overall conclusion about the work and related findings are presented. Implementing Lean management in an organization is a concept that is designed to support the concept of continuous improvement in a manufacturing and support organization. Using this approach will systematically seek to achieve small and incremental changes in processes in order to improve efficiency and quality. Lean principles will continue to be used to reduce waste and improve processes. The Lean management process when used correctly seeks to eliminate any form of waste in reference to time, effort or money by identifying each step in the business process and revising steps that does not create value. Total Productive Manufacturing (TPM) is a structured equipment-centric continuous improvement process that strives to optimize production effectiveness by identifying and eliminating equipment and production efficiency losses throughout the production system life cycle through active team-based participation of employees across all levels of the operational hierarchy. Although TPM is historically equipment-focused, effective implementation offers a continuous improvement methodology to increase overall manufacturing productivity. TPM methodology provides enterprises with the tools required to explore, increase, document, and proliferate organizational learning. Today, with increasing competition and tough markets, TPM may decide the success or the failure of a company. TPM has been a proven program for many years and organizations, especially into manufacturing, can adopt this methodology without any risk. 31 Figure 22: TPM Figure 23: Implementing TPM 32 REFERENCE https://purpose.nike.com/waste https://news.nike.com/news/history-of-nike-air http://manufacturingmap.nikeinc.com/ https://www.britannica.com/topic/Nike-Inc https://news.nike.com/news/nike-air-manufacturing-history http://tuhinternational.com/2012/08/26/original-nike-air-bag-patentdrawings/original-nike-air-bag-patent-drawings-01-570x837/ 33
