The Power of SMED

1. What is Single Minute Exchange of Die (SMED)? Single Minute Exchange of Die (SMED) is a simple but powerful Lean technique for reducing waste in a manufacturing process. It is a systematic approach that enables organizations to dramatically reduce set-up time or changeover time. It provides a rapid and efficient way of changing the machine set-up in a manufacturing process from one product to another. 2. Why is the SMED important to improving manufacturing flexibility? SMED reduces the set-up time. Long set-up time resulted in a reduced number of set-ups, larger batch sizes and larger buffering work-in-process inventories and poor process flow and performance. Since set-up activities add no marketable form, fit, or function to the product, they are by definition non-value adding. By reducing set-up time, more set-ups can be completed each day, batch size can be correspondingly reduced, flow can be significantly improved. All these improvement will help to improve manufacturing flexibility. 3. What is the history of Single Minute Exchange of Die (SMED) method? Single Minute Exchange of Die (SMED) method was pioneered by Mr. Shigeo Shingo since 1950 in Japan, but only became popular to the other part of the world in 1980s. 4. What are the 4 stages of Set-up Reduction? Stage 1. Ensure that external setup actions are performed while the machine is still running, Stage 2. Separate external and internal setup actions, ensure that the parts all function and implement efficient ways of transporting the die and other parts, Stage 3. Convert internal setup actions to external, Stage 4. Improve all setup actions. 5. What is the definition of Internal and External activities? Internal activities are those that can only be performed when the process is stopped, while external activities can be done while the last batch is being produced, or once the next batch has started. Examples of external activities include pre-heating of raw material and preparation of tools before the machine stops. 6. What is the best way to see immediate results when implementing SMED technique? One of the best ways to see immediate result of the technique is to perform a kaizen event using SMED technique on a pilot machine. The kaizen event usually takes about 3 to 5 days and will repeat the 4 stages of SMED over several iterations. A good rule of thumb is to target 50% improvement for each iteration, and repeat the process until the target is achieved. 7. How can SMED helps in Lean implementation? Most people's initial reaction to the quantum improvement brought about by SMED is disbelieved, followed by total acceptance and commitment to Lean transformation. So if you need to gain some ground support and buy-in in your Lean implementation, consider a pilot project on SMED for a good head start!

Why You Want to be a Six Sigma Master Black Belt ?

The Sigma level of a process describes the performance of a process or product characteristic when compared to a customer specification. A Six Sigma process exhibits no more than 3.4 defects per million opportunities. Very few business processes achieve this level of performance and consequently most organizations endure very high costs and poor quality. Most company processes produce in excess of 6000 (approximately Four Sigma or less) defects per million opportunities which is often simply not good enough for today's competitive environment where customer demands increase exponentially. Achieving a Six Sigma level of performance requires that a systematic customer focused methodology and disciplined project selection and execution framework be deployed throughout your company. To achieve such a deployment people at all levels of the organization must be trained in Six Sigma. Six Sigma identifies Five Key Roles for its successful implementation. These are Executives, Champions, the Six Sigma Master Black Belt, Six Sigma Black Belts, and Six Sigma Green Belts. While all these roles are important the Six Sigma Master Black Belt plays a pivotal role in your companies Six Sigma deployment. A Six Sigma Master Black Belt will coach managers, partner with Champions and guide Black Belts and Green Belts as they work to complete their projects. Master Black Belts possess a unique combination of soft (people) skills and hard (technical) skills. Successful Six Sigma Master Black Belts are your future business leaders. They have advanced knowledge and experience applying Lean, Six-Sigma and Lean-Sigma methods and tools. They can help your company fully internalize your Lean Sigma Deployment and reduce or remove your dependence on outside consultants and suppliers. They consistently solve your toughest business problems. They are able to share their expertise effectively with others and generate infectious excitement around your Lean Six Sigma program. Six Sigma Master Black Belts also facilitate project selection and project reviews. They mentor, teach, coach and lead Black Belts and Green Belts to successful project completion. They consistently deliver exceptional bottom line savings and top line growth for your company. Sigma Breakthrough Technologies offers a comprehensive and challenging Six Sigma Master Black Belt training program for the development of Six Sigma leaders. It is the benchmark for continuing development of Six Sigma training and deployment resources. SBTI's Six Sigma Master Black Belt core training program provides a powerful and unique combination of advanced hard and soft skills training. Early in a Six Sigma Lean deployment a great deal of a companies success results from "picking the low hanging fruit". The tools required to solve these problems typically include a Project Charter, Process Mapping, Cause and Effect Matrix, FMEA, a few simple statistical tools and a Control Plan. These projects are typically localized and are fairly easy to lead and manage. Once the "low hanging fruit" begins to dry up companies are left facing the big chronic business problems that have been plaguing them for years. These business problems often require a combination of advanced statistical skills and superior leadership and people skills. Fifty percent of SBTI's Six Sigma Master Black Belt program focuses on advanced statistical skills. These advanced skills enable the Six Sigma Master Black Belt and the belts they coach to deal with the complex data structures that often underlie a company's toughest business problems.

How to Ensure Quality Control on your Products ?

In the manufacturing, most suppliers strive for their own production of a level of quality control in every product category. There are a lot of different ways or measures to ensure the quality of interlining merchandises, ranging from the actual product performance itself to the physical composition components of the product. Though there are many ways to improve quality control. Here is a list of some ways that you can rely on to improve the control on quality of the interlining products. Firstly, of all the measures and ways to ensure the quality of interlining products, quality control tests and inspections are the greatest ones. Traditional interlining suppliers only have live inspector or testers to perform an audit of control on quality. However, pioneer interlining suppliers like Interlining Source also perform an automated inspection. The option of a live test or an automated inspection depends on the manufacturing process and the type of the products. For example, some types of woven interlining need a live test, while others require both. This is also true to non-woven interlining and fusible interlining. The testing procedure itself is also a key factor to determine the option. In addition, It is recommended the interlining supplier to train the individual employees within the company in quality inspection, rather than hiring a live inspector. This is already becoming a popular option for the interlining suppliers. Not only the company can save money on the additional head count, but also quality control training for the production workers will help improve the quality of the products. This is because that control on quality improvement has become an additional assigned task for the employees in the production lines for products like woven interlining, non-woven interlining and fusible interlining. By this training way, the company will not only get merchandises manufactured and quality improvement inspection done with the same employee at the same time, but also lower manufacturing costs. Secondly, another way you can apply to ensure quality control on interlining products is computer software. There are many leading software providers that help the interlining suppliers to manage control on product quality. Some software is very helpful in increasing the product performance. For example, leading software can track the quality of products to the RoHs Directive. Indeed, if the interlining suppliers need to adhere to restriction of the use of specific hazardous substances in their quality control testing, such software might be helpful in improving the control on product quality. A third way to ensure quality control of interlining products is using charts and graphs. By applying the charts and graphs, the interlining suppliers can map out whether their products like woven interlining, non-woven interlining and fusible interlining are meeting quality specifications. Generally these maps and charts are applied after the quality control inspection, test, or quality experiment is completed. By following comprehensive analyses and stringent observation on the charts and graphs, the interlining suppliers can get a betting idea on weakness point of the quality control on the products in interlining industry. All these ways are only a starting point to get an idea to ensure the quality control on interlining products such as woven interlining, non-woven interlining and fusible interlining. The pioneer supplier like Interlining Source is striving for the linkage between six sigma management and the interlining manufacturing. This is, perhaps, the current ultimate way to ensure control on the product quality.

Lean Six Sigma vs Six Sigma

There is always a debate in the business world between lean six sigma and six sigma what is the best suitable process to implement when it comes to organizing processes pertaining to business and eliminating wastes. Both these systems have their supporters, claiming theirs to be the best. For clearly understanding the debate, it is essential that the differences between the two systems should be understood. Let us figure out and get deep into this: Six sigma fundamentals: The main objective of Six Sigma is the elimination of wastes and defects for ensuring that efficiency and quality improvement is possible by streamlining processes. Initially, even though it was designed for use in manufacturing, it was quickly identified that it can be useful when applied to all aspects of a business; right from introduction of product/service to providing the appropriate support to customers post sales process. Nowadays, it plays a critical role in leadership and large-scale implementation of this system will be helpful for a company to achieve measurable results. What is Lean Six Sigma? This methodology is also used by companies in production and other processes. The purpose behind its usage is cutting down any unwanted steps in the process of product manufacture in such a way that steps that can directly add value to the products. When the unwanted processes are removed, the production can be quickened as well. When it comes to the lean approach, the only ideal method for determining if something has value or not is to find out whether a customer will be ready to pay for it. Combining both: Both have the same objective. Both of them try to eliminate waste and aim at creating the most efficient system possible. But, different approaches are taken by them for the achievement of the goal. The important difference is that they discover the fundamental reason behind the waste in a different manner. It is believed by lean practitioners that wastes arise out of unwanted steps in the process of manufacturing. These unwanted steps do not even add value to the product. On the other hand, it is pointed out by Six Sigma supporters that wastes can differ based on the variations taking place within the processes. The fact is that both of them can be highly helpful and this is the reason behind many businesses using them and is suggesting their employees to join in six sigma green belt certification and black belt programs. Experts suggest that these training programs can be very helpful in quality management for businesses. They suggest the following reasons as to why this tool should be used. When the employees are provided with the appropriate training, they can make use of statistical data for ensuring optimum profits to their employers. The usage of data can also help in meeting the satisfaction of customers with respect to quality of products. It will also be possible for them to compare each and every process within the organization. This will ensure better assessment. The training can enable efficient use of working force and their abilities. Differences between lean six sigma and six sigma: Wastes can be eliminated when both the techniques are applied. The team of personnel trained under the lean technique can focus on improving the speed of the process by effectively reducing wastes. On the other hand, team working on six sigma can focus on eliminating chronic problems. Both these teams can implement DMAIC and DMADV in an efficient manner and prove to be valuable assets to their companies. To conclude based on comparison, it purely depends on the requirement of the employer whether they provide training to their employees in six sigma or lean. Even though, removal of unwanted wastes is essential, unwanted problems arising in the processes can create issues in the whole process itself. So, many employers prefer six sigma certification over lean training. In today's education scenario, since the online learning or e-learning became popular, professionals need not travel all the way to the venue of the training institutes and straight away pursue online training for this kind of course. Care should be taken whether the institute is accredited to ASQ examination body or not. Any registered institute is termed as ATO.

How to Reduce Processing Time By 50% in your Office ?

Since 1973, family owned Dalco Metals of Walworth has been a premier supplier of flat-rolled steel-processing services to manufacturers throughout the Midwest. John Ring, executive vice president of Dalco, credits this long-term success to the company’s focus on the customer’s needs, close relationships with suppliers, and constant attention to quality in every manufacturing and business process. “About eight years ago, it seemed that everything pointed toward adopting lean manufacturing methods: a customer recommended we look into lean manufacturing, a classmate in my MBA program recommended 5S (a lean method), and I attended the Manufacturing. Matters! conference and participated in a Lean workshop presented by WMEP. 5S is not a static tool – Dalco Metals continually works at sustaining the changes they’ve made and to continually find new ways to make the process better, cleaner, faster and less expensive. “Dalco Metals is a great example of what it takes to generate the benefits of Lean manufacturing over the long-term,” said Thiltgen. “Many companies start lean programs, but lack the stamina and commitment it takes to fully realize the benefits gained when Lean is a way of life. Dalco Metals has tremendous executive support of Lean – it’s a part of everyone’s job.” Chuck Ferguson, inside sales and applications manager, agrees. “The ‘sustain’ part of the program is the toughest part. We are trying to ingrain the 5S mentality in everyone’s minds here at Dalco and I think it is working. As long as we have the support of the management, Dalco will continue to operate at peak efficiency.”

Lean Manufacturing Concept VS Traditional Quality Concept

Have you ever thought "quality products are expensive"? You might be prepared to pay some extra money for a high quality product. I believe you have taken the correct move. It is always better to buy a better quality product or service than a low quality one. But I have a small problem regarding your concept about higher price you are paying. Why you should pay extra money to get good quality product. Strange question isn't it? But I believe it is very much a valid question. I do not believe that you have to pay extra money for the quality. I will explain why. There are two types of manufacturers around. One is quality manufacturers. They produce quality products and services. Lean manufacturers are naturally quality manufacturers. The other type is average manufacturers. They produce average quality products. They pick best from these products. These selected products are high in quality of cause. Then they sell these products as high quality products. Remember these are not quality manufacturers. They are quality pickers. When your manufacturer is a quality manufacturer, you will be paying only for the products you are buying. It is obvious isn't it? You will pay only for the products that you buy. But when you buy a product manufactured by a quality picker, you are paying for the other low quality products as well. Have you thought before? You are actually paying for the product you are buying, and you are also paying for the products which are removed in selecting best quality products from the bunch of average quality products. The cost of low quality products are added to the high quality product. That is why most of the manufacturers will say "High quality products are costly". If this is a lean manufacturer he will say "Cost is free" instead.

Lean Six Sigma and Productivity

Lean Six Sigma is all about improving quality and minimizing errors. It can help to speed up manufacturing and most any other business process. This is mostly because it creates an infrastructure of people in an organization that are experts at their given level of Six Sigma knowledge. They have a specific job, know how to carry it out and will help reduce cost and increase profit. This is their main mission. Since 1986, this method has been working. There are six steps to the process that have to be carried out exactly for it to work properly. These steps concentrate on getting more out of less work and eliminating the defects that exist in product development. It basically accelerates the decision making process within the company. In today's economy, that is priceless. Most companies these days could use more production with less pay. With big companies like Toyota adopting this philosophy, its success is easy to recognize. By identifying waste, transportation issues, inventory issues and equipment failures, companies can significantly cut costs and speed up production. Many times it can cut costs by 50%. In this economy, that is amazing. It can actually help to eliminate layoffs. Employees find that adopting this methodology a much better solution to declining sales, especially when they get to keep their jobs. Since Lean Six Sigma focuses on management, it works. The employees will not only accept the changes but will be less frustrated in the end. They will be able to do their job and do it much easier. In fact, using the Six Sigma process will end up creating stronger communication between management and the employees. When tensions are very high, this can really be a blessing. No company really likes to have problems with communication between management and employees. The strategies are simple. They include defining, measuring, analyzing, improving and controlling for process improvement. This is otherwise known as the DMAIC method. When these elements are attended to, they can be powerful tools for identifying and eliminating waste in process and productivity. This method minimizes inputs and wasteful outputs, and will result in overwhelming inventory at lower cost. When productivity is low and stagnate, a new way of management needs to be developed. That is just the way manufacturing works. Changing things up can accomplish a lot and sometimes be so vital that the future of the company may be in jeopardy without it. Having the proper training and implementing a new process can take time and money, but in the end it is very much worth it.
