Lean Six Sigma Implementation Basics

Lean Six Sigma methodologies are a combination of standard 6-Sigma quality improvement techniques and lean manufacturing principles that are used for speeding up business processes. 6-Sigma methodologies focus on reducing defects in business processes, whereas Lean 6 Sigma does not only eliminate defects but also improves the speed of a process and reduces waste by eliminating non-value added steps in a business process. Combining 6-Sigma and lean manufacturing principles is like combining the contents of two different toolboxes that help companies to improve quality and efficiency.

Compatibility

Depending on the type of methodologies used by an organization, Lean Six Sigma is often referred to as Lean Service, Lean Manufacturing, and Lean Enterprise. These concepts are compatible with standard Six Sigma methodologies and can be applied to every type of business processes. Both the concepts use similar strategies and methods and focus on improving business processes that serve customer needs. Both focus on identifying and eliminating sources of waste and processes that do not add value for maximizing output, efficiency, and throughput. They emphasize providing requisite training for enabling employees of an organization to understand the tools and processes of the methodology. Both concepts encourage the involvement of senior managers and key mentors within an organization for ensuring that quality improvement projects are executed without affecting the day-to-day operations.

Lean 6 Sigma uses different techniques for reducing costs, reducing production cycle times, expanding capacity, and improving productivity. It uses "value stream mapping" for identifying improvement opportunities. However, Lean Six Sigma concepts may sometimes prove inadequate in solving some of the more complex problems that call for advanced analysis.

Benefits

Standard 6-Sigma methodologies follow a disciplined, data driven approach and use statistical tools for analyzing quality at every stage of the production process. When combined with Lean manufacturing principles, it helps in identifying and resolving quality issues. Its successful implementation is important in reaping quick results and enabling employees and plant managers to harness better work patterns on plant floors. Lean Six Sigma programs are executed under the guidance of 6-Sigma Champions and Black Belts for enhancing the efficacy of quality improvement initiatives. It is necessary to deploy lean manufacturing techniques during the Six Sigma implementation process for ensuring that the improvement process includes a standard problem-solving approach.

Lean Six Sigma focuses on adding value to manufactured goods or services rendered by eliminating defects in every business process. This helps in building customer loyalty, as customers often prefer products and services that offer consistent quality. The matrices used in Six Sigma help in identifying customer needs, manufacturing quality products and rendering quality services.

Lean Six Sigma concepts and methodologies are based on a highly sustainable approach that gets easily integrated with the existing work processes within an organization. It requires the involvement of employees at all levels within an organization. The deployment of 6-Sigma programs can initiate a culture shift within an organization that helps in eliminating waste within the production process.

Lean Six Sigma helps in ensuring future success of an organization by radically improving quality and reducing waste. It also allows employees within an organization to design and develop new business processes that will help in making drastic improvements to the organization's performance.

Identifying And Selecting A Six Sigma Consultant

When tested quality programs such as Six Sigma are implemented the right way, process improvement in a company can result in tangible gains within 3 to 6 months. Employees feel satisfied and ultimately, the shareholders also benefit from the overall results. While it is possible for business owners to study quality initiatives and effect changes within their organization on their own, sometimes an external consultant with expertise in Six Sigma might be the best person to help lead the change. Consultants are immune to a company's internal politics and have the advantage of exposure to information and best practices from other companies where they have implemented the procedure.

Choosing The Appropriate Consultant

Selecting the right Six Sigma Consultant is a vital decision that can have a tremendous effect on your business. Ways to assess a Six Sigma consultant include checking if their experience is relevant, if their track record is successful, if they are willing to impart their knowledge systematically and if they are skilled at training and facilitation.

Features Of A Good Consultant

- Six Sigma Consultants should have a unique blend of skills in Six Sigma and relationship management in team development and conflict resolution. - They should serve as good communication lines between the employees or the customers and the leaders of the organization. - They should take adequate responsibility for writing projects, documenting them and making decisions for the project. - They should be able to lead the projects and facilitate conferences. - Six Sigma consultants should also be able to make presentations to associates and contribute to a company's change of management process.

Selection Criteria

- The key to selecting a good Six Sigma consultant is becoming aware of the specific needs and work culture of your firm. - Companies hiring a Six Sigma Consultant should initially perform a careful assessment of their internal environment and then formulate a team that can oversee the whole process. - The company should know whether it requires a full Six Sigma service implementation or whether it only requires training. - The main reasons for hiring Six Sigma Consultants should be their expertise on certain subject matters, are skilled at communication, be it written or verbal, are unbiased and can implement their skills within the company in a non-partial manner. - Accountability is also an important consideration; if the implementation doesn't work then it can be placed squarely as the responsibility of the consultant. From an owner's point of view, it's easier to blame an external consultant than to take sides within the company itself. - Cost is certainly a major factor while choosing a consultant but it should not be the only one. The professional fees charged by Six Sigma firms can vary from reasonable to very expensive and the key consideration should be the value that the consultant brings to the organization.

Pre-Hiring Measures

- It is advisable for companies to identify about 10 Six Sigma Consultants and ask for a proposal, based on which, they could shortlist 3 to make a presentation. This method of selection has worked very well for many companies. - Background information about a consultant can be obtained from other businesses that have been through the process before. - It is important to select a firm with more than a few years of Six Sigma experience. - During the selection process, team leaders must decide what role the consultant has to play during the project. The consultant can be a strong facilitator and an experienced practitioner, a team member or a subject matter expert. - To fit into any of these roles, a consultant has to have strong facilitation skills, in-depth process knowledge, industry exposure and should be able to perform specific tasks for the team.

Six Sigma and Online Training by Peter Peterka

While nothing can exceed the breadth, depth, and quality of direct in-person training, various factors can make it inconvenient. If your organization is serious about Six Sigma training, but find it difficult to get everyone together for instructor-led training, then an online Six Sigma course is a worthy alternative. An online training program can give your organization more flexibility and even reduce your training costs.

Online training has been shown to be useful for many learning applications and Six Sigma is one of those. The advantages of online training over instructor-led training are simple but profound. There is considerable savings in cost as online instruction is less expensive than in person classroom training and there are no travel expenses. Also online training offers greater flexibility in scheduling and causes less interruption in work schedules.

An online training course combines the advantages of uniformity in training and self-paced training. The basic course is the same for each trainee but can be delivered to different people at different times. While a human instructor is only available a limited time, online training materials don't "go home" and trainees can review the subject matter as needed or desired. Support can be supplied via e-mail or phone. This scheduling flexibility is one of the benefits of online training. Six Sigma courses can be made available for a specific amount of time. For example, you could be granted access to the course material for four weeks which could be extended an additional two weeks on request at minimal or no extra cost.

The electronic format of online training makes it easier to tailor training to your specific needs. Training can be split into modules and you can present different modules to different people in your organization giving them only the training they need to fulfill their role. A Six Sigma online training program can provide an overview of the Six Sigma concepts and tools while going into detailed procedures and knowledge as needed. Those who need the basics of the Six Sigma methodology can receive it in a concise and easy-to-understand format. Those who need more advanced topics such as Six Sigma deployment practices, project development, and the DMAIC problem-solving approach can receive those.

Six Sigma training in an online electronic format focuses on active and applied learning methods where people can interact directly with the material and tools. Trainees are able to view samples of Six Sigma projects including some of the methods used within a Six Sigma project. Trainees can also get hands-on experience using some of the many statistical tools used in Six Sigma. Rather than just hear about statistical methods, they can see how they work in a spreadsheet in front of them. They can play with the numbers and even practice computing for variables to see directly how the tools function.

The online format also gives you more control over the training and greater assurance that your people are achieving each learning objective. Well placed mini quizzes can be employed to check for student understanding and give immediate feedback. Trainees will know in "real-time" whether they understand the concepts presented and the online course can provide repetition of content if needed. Trainees can spend more time on the modules you need. --invest as much or as little time as appropriate for you and not a class on each module.

Online training most likely will not require any additional equipment at your location. Training is delivered through existing computers and an Internet connection. Most online courses will run through any Internet browser on any operating system. You will need to dedicate newer and powerful computers to the training is the course has graphics, sound or video. Don't make the mistake of using old castoff computers as your training computers. That will just make your trainees frustrated.

A well designed Six Sigma online training course can be highly effective. The flexibility of scheduling and content delivery, plus the cost savings make online Six Sigma training either as an addition to or a replacement for the face-to-face classroom environment, a strong part of your organization's Six Sigma deployment.

The Six Sigma Method And Design Of Experiments

Six Sigma is becoming a proven approach for businesses and organizations to improve their performance. The spectrum of companies actively engaging in Six Sigma today is wide from industrials like Celanese, Caterpillar, GE, Honeywell, and 3M to service/retail organizations like Starwood Hotels, Sears, and Home Depot. Six Sigma has even started in the financial industry with Bank of America and JPMorgan Chase initiating major deployments in the past two years. Probably the most exciting area is in the public and healthcare sectors with success stories emerging from city government and John Hopkins Medical.

Six Sigma has even started in the financial industry with Bank of America and JPMorgan Chase initiating major deployments in the past two years. Probably the most exciting area is in the public and healthcare sectors with success stories emerging from city government and John Hopkins Medical.

So what is all this excitement about? Havent these quality tools been around for years? Is it just the fact that people have strange names like Champion, Green Belt, Black Belt and for the chosen few, Master Black Belt? Okay, if it is not the names then what? Six Sigmas success revolves around the fundamental elements needed for any successful organization. Six Sigma starts with a vision of delivering products and services to customers with no defects from the eyes of the customers. For companies it is vital to deliver these products and services at a profit. Once the organization has created their own vision of Six Sigma, the business leaders need to define their organizations objectives in numerical terms. These high-level metrics, often called big Ys in Six Sigma, are the foundation for identifying project ys that Six Sigma Belts will execute projects on. With big Ys in hand, business leaders called Six Sigma Champions breakdown these organizational level Ys into smaller ys a project leader called a Green Belt or Black Belt can work from.

So whats next, do business leaders take a hands-off management by objectives (MBO) approach of, I dont care how you do it as long as you get results!? For Six Sigma organizations the answer is a loud NO. Champions do care how projects are executed and have appointed highly trained Master Black Belts to assist and mentor project leaders in applying the Six Sigma method to manage their projects. I believe this is the key to Six Sigmas success. In a past life I participated in a high-level meeting with executives from the world leader in the production of a product we all know. The purpose of the meeting and visit was to evaluate a critical new product design. All of the high-tech executives were dressed in dark Italian business suits complemented with gold and diamonds. I listened closely to each question these executives asked. I never once heard how much?, when? or even why? every question was by what method?. Methodology is what Six Sigma is about.

Six Sigma Methods

There have evolved two key methods for carrying out Six Sigma projects. The first method is the most well-defined and works best if you have a problem with an unknown solution in existing products, processes or services. This method is called DMAIC or Define, Measure, Analyze, Improve and Control. The newest method, which is in the developing stages, is called Design for Six Sigma or DFSS. The goal of DFSS is to develop a new product, process or service that is defect-free in the eyes of the customer. A number of consulting companies have invented roadmaps for DFSS like IDOV (Identify, Design, Optimize and Validate) and DMADV (Design, Measure, Analyze, Design and Verify).

Six Sigma and Design of Experiments

Once an organization has decided on the method and the project ys, Belts are marched off to training waves bringing management-approved projects to class. DMAIC Green Belt training is normally two one-week sessions separated by one month. Black Belt training waves are extended by two additional months with two more weeks of training. The emphasis during the extended two weeks of Black Belt training is often on learning more details about advanced tools such as Design of Experiments (DOE).

So where does Design of Experiments fit into Six Sigma? Six Sigma is about understanding and controlling the variation of key process variables known as inputs or xs in order to obtain improved results on project outputs or ys. In Design of Experiment terms these inputs or xs are often referred to as factors and the outputs are referred to as responses. In nearly all Six Sigma projects the relationship of the project ys takes on the form of y=f(x1,x2,...xn). Wait a minute, isnt this what Design of Experiments is all about? Of course, for almost 100 years Design of Experiments has been proven to be one of the best known methods for validating and discovering relationships between responses and factors. In Six Sigma terms it is discovering the relationship between outputs called ys and inputs called xs. Todays Six Sigma Belts are primarily taught to focus their use of Design of Experiments in the Improve phase of DMAIC and the Optimize phase of IDOV. For DMAIC Six Sigma training the most common experimental designs taught are factorial and fractional factorial designs. Some curriculums introduce response surface designs and optimization designs at a high level. DFSS includes the experimental designs taught in all levels of DMAIC training and often expands to include the concept of robust designs. As an alternative to the classical approach, there are also a number of consulting companies teaching Taguchi designs as the
preferred method for robust design.

Final Remarks

Six Sigma looks as though it is here to stay and even in todays slow economy one of the few areas where there still are a number of new positions. The Six Sigma process is a great step toward creating learning organizations with its well-defined roadmaps and management structure. As with most new methodologies Six Sigma will mature and grow as it expands into new areas such as DFSS. As Six Sigma professionals learn more about the power of properly planned experiments, Design of Experiments will be integrated into most phases of the Six Sigma roadmap and not just considered an advanced tool for the improvement and optimization phases. Experienced practitioners of statistical methods like Design of Experiments should learn the language of Six Sigma and help integrate new methods into the Six Sigma process to improve its effectiveness.

The 6 Steps to Six Sigma

Step 1

Get the proper level of Six Sigma expertise at the executive level of the company. If the top leaders don’t understand the advanced six sigma principles, the company has no shot to attain total quality. This will probably require a hefty budget, entailing the hiring of several high-priced consultants for long periods of time. The consultants need to observe and gather data about the companies operations, and show the executives how to interpret the data.

Step 2

Get the staff involved. The ones in the trenches are the most knowledgeable about the day-to-day operations, and the day to day’s are where most costs are spent. This means getting people like the shop foreman, the line supervisor, and the office manager involved in the training. Not only do they need to understand the thinking behind six sigma, but they also need to buy into the benefits. Since they’re the ones carrying out the orders and directing the vast majority of employees, if the trench-level staff isn’t aligned with management, the company is sunk.

Step 3

Measure the data - quantify the number of defects per unit. This applies not only to manufacturing, but to services as well. It’s easier to measure defects on an assembly line. You just divide the number of defective units by total output (that’s really simplified, but you get the point). Services are more vague.

This is why it is vital to get input from your customers. Ask them how things are going from their perspective. Is there anything they would like to see you improve on that would make their experience more favorable? You’re looking to increase overall quality. Nobody knows your faults better than your customers.

Everything must be measured and quantified into actual numerical data. How long does it take the average customer order to ship? What percentage of customers is satisfied with your performance? What is the average employee break time? How long does it take the customer service department to answer the phone? Once enough data is gathered to answer questions like these, the six sigma process and the path to quality improvement can begin.

Step 4

Now you must analyze all of the data that has been collected so far and identify the difference between perfection and your current operating efficiency level. The goal is to constantly close the gap between the two. Again, as stated in Step 2, staff buy-in is extremely important. If management does not show a link between "total quality improvement" and "workplace improvement," then all the data collection will go to waste. The staff will not willingly take the extra steps (which often require harder, more detailed work) if they are not being rewarded. Some companies use bonuses to provide incentive, other companies offer prizes for attaining goals or add employee perks based on improvement levels.

Step 5

Now is the time for improvement. Changes in procedure and operations should have been in place, and more data should be collected to gauge the level of overall quality improvement. Either the hired consultants or an internal team of Six Sigma Black Belts should supervise the data collection. Again, this step will be expensive. Gathering the vast amount of data needed to accurately assess performance takes a great deal of time, resources, and capital. But without proper data and measurement, you will never know if the changes are working or not.

Step 6

After improvement begins, the constant chore of ongoing control must be monitored. Unforeseen variables will arise. Employees may turn over, competitors might introduce new products, your facility may undergo changes, and many other things could happen which will impact the overall quality of your business. Top level Black Belts need to be constantly analyzing data to gauge the impact of any future changes, spot possible trends, and formulate actions to keep on the path of consistent and eternal improvement.
