Lean Six Sigma Certification process

Six Sigma Certification

Six Sigma certifications can be taken from different certification bodies like the International Association for Six Sigma Certification (IASSC). This means that before you commit to a program, all the individuals or companies looking for the certification must compare the programs by researching them. Every certification body has a non-identical, yet similar, hierarchy of the Six Sigma certifications. However, the standard for most of the programs are:  

  • Yellow Belt - for the team member of a project supporting the project improvements.
  • Green Belt - for the team member supporting the project improvements, leading the projects part-time, and helping with the statistical analysis.
  • Black Belt - for the team member leading the project full-time as well as training and supervising coaches and project members.
  • Master Black Belt - for the team member developing project strategy and metrics, training and coaching Green Belts and Black Belts, and serving as the go-to Six Sigma person in the organization. 

Unlike other IT certifications, these certifications do not exist as a ladder. Meaning that you don’t need a yellow belt to get the Green Belt, or the Green Belt to get the Black Belt. There is no lower-level prerequisite for any belt. 

Below are the eligibility requirements of each Six Sigma certification: 

1.  ASQ

  • For the Yellow belt certification, there is no education or experience requirements.
  • For the Green belt certification, you need to have three years of experience working in an area of  IASSC Lean Six Sigma Green Belt Body of Knowledge™. This experience must be in a paid, full-time role. They must have participated in a quality improvement project where they had demonstrated the knowledge of processes and tools of six sigma. 
  • To be eligible for the Six Sigma Black Belt certification from ASQ, you must either have signed affidavits stating that you have completed two projects or one project alongside three years of working experience in an area of Body of Knowledge. All the work experience must be in a paid, full-time role. 
  • For the Master Black Belt certification from ASQ, you need to have an ASQ Black Belt certification and pass the portfolio review process of MBB. Also you must either have completed 10 six sigma projects as a black belt or have at least 5 years of experience working as MBB or SSBB.   


  • There are no prerequisites for the IASSC Certified Lean Six Sigma Yellow Belt™ (ICYB™) , IASSC Certified Lean Six Sigma Green Belt™ (ICGB™) , and IASSC Certified Lean Six Sigma Black Belt™ (ICBB™)  from IASSC.  


  • The Six Sigma Yellow Belt certification from CSSC has no prerequisites. There is no project requirement either. 
  • There are no prerequisites for the Green belt certification from CSSC. Also, there is no project requirement. However, you need to pass this certification exam for pursuing the Level II Green Belt certification. 
  • For the Six Sigma Black Belt certification from CSSC, there are no prerequisites. There is no project requirement. However, you need to take this certification exam to be eligible for the Level II Black Belt certification. 
  • For the Six Sigma Master Black Belt certification from CSSC, you must have a signed affidavit stating that you have a minimum 4 years of working experience in the six sigma projects as a Black Belt. Also, you need to complete a project that must be different from the level II or level III black belt certification. 

1. Yellow Belt certification cost

This belt demonstrates your knowledge of the foundational concepts of the Six Sigma approach. The cost of the exam depends on the organization you are using for the certification. Through IASSC, the certification will cost you $195. The CSSC provides the certification at a much lesser price of $79. The ASQ has different rates for its members and non-members. The price of certification for a non-member is $394, while a member can save $100 and get multiple discounts in future certifications through ASQ. There will be varying costs if you use your school, a local provider or an independent program. In most of the cases, this cost will be less than $200. 

2. Green Belt certification cost

This certification is used for distinguishing individuals with knowledge of Six Sigma from individuals who can lead projects of Six Sigma. The members of ASQ have to pay $338 for the exam while the cost of the exam for non-members is $438. Every retake will cost $238. The CSSC provides the Green Belt certification in two levels. The first one is the standard and the second one is additional for  proving their efficiency. The price of the CSSC certification is $119. The additional certification will cost $300. The exam fee for the IASSC certification is $295.  

3. Black Belt certification 

This certification is for major Six Sigma professionals who are leading the implementation process of Six Sigma. For ASQ certification, members pay $438 and non-members pay $538. If you are applying for recertification, the price for members is $388 and non members is $498. The CSSC offers four levels of Black Belt certification. The cost of the basic level is $159 and the cost of level II is $300. The cost of level III and Master Black Belt level will cost $300 and $665 respectively. The IASSC charges $395 for its Black Belt certifications. 

If you are planning to work in the field of Quality Management in the domain of manufacturing, healthcare, pharmaceuticals, or service industries, a Six Sigma certification will put you ahead of your competitors.   

For example, if you have just started in the field of quality improvement, you can go for the Six Sigma White belt. All certified candidates have been trained to use the Six Sigma approaches. They have the knowledge of the fundamental concepts and the basic vocabulary of the methodology. In other words, if your company works with the Six Sigma approach then you would need this Six Sigma certification. 

Now, if you are a member of the Six Sigma team, you might consider taking the Six Sigma yellow belt certification. You will have more knowledge of the methodology than the white belt. Also, it will allow you to be a productive and functioning member of the Six Sigma team. However, with this certification, you will not be able to lead a team.  

For becoming process leaders and working within the processes like in the manufacturing line or the accounting group, you need to get Six Sigma Green Belt certified. You will have the ability to implement Six Sigma projects in the department. You need this certification if you want to lead a team through project toolset and framework, reduce defects, and evaluate solutions. This certification will help you get ahead in your career by increasing your marketability. 

You need a Six Sigma Black Belt certification for implementing strategically important and complicated improvement projects. With the certification, you will have the ability to solve process problems and acquire cross-functional and leadership skills. You will also be able to mentor or coach Green Belts.   

Six Sigma Master Black Belt is for the most skilled and comprehensively trained practitioners. They are experts in strategic management, facilitation, leadership, and root cause analysis. With this certification, you will be able to lead any team of Six Sigma. You will be setting a strategic direction for your enterprise, removing roadblocks for assigned Green Belts or Black Belts, and overseeing and delivering training of other employees. 

Here are the different levels of Six Sigma belts: 

1. Yellow Belt

This certification will demonstrate that you have the foundational knowledge of Six Sigma. However, you won’t be able to lead any Six Sigma projects. You will be supporting the Six Sigma team by helping create process maps. You might be considered as a subject expert and be a part of a team in a Six Sigma project. As a yellow belt, you will be actively participating in less complicated projects of process environment using PDCA or Kaizen. PDCA (Plan Do Check-Out) is a technique created by Dr. Deming for continuous improvement. You can graduate to the Green Belt or Black Belt level where you will be maximizing the savings of bottom line to an exceptional level using the DMAIC methodology. 

2. Green Belt 

Green Belt has knowledge and expertise in all aspects of all phases of DMAIC. Under the guidance and supervision of Black Belts, Green Belts professionals operate for analyzing and solving issues related to quality. They are known for participating in projects of quality improvement. Black Belts lead cross-functional projects whereas, Green Belts lead projects that are within their functional area. They are responsible for scheduling regular meetings with their Black Belt mentors for seeking advice and reviewing the progress of the project. They also assist Black Belts in looking out for process gaps and lead projects of process improvement in their work area.  

3. Black Belt 

A Black Belt certified has a high level of knowledge of principles of Six Sigma like supporting tools, systems and techniques. They are responsible for maintaining team dynamics, allocating roles and responsibilities to the team members, and exhibiting leadership as problem solver. They are familiar with the DMAIC methodology’s aspects aligned with the principles of Six Sigma. Due to their knowledge of lean concepts, they are able to figure out the activities that are non-value-added and what tools should be used for reducing them. Not only do they mentor the Green Belts on projects of organizational improvements, but also coach and lead a cross-functional team consisting of Yellow Belt and Green Belt projects.  

4. Master Black Belt

These professionals convert the high-level business goals of the organization into a Six Sigma strategy and supporting tactics for the division. They oversee the development of skills related to Six Sigma in the organization for the yellow belts, Green Belts, Black Belts, and the general base. They are also responsible for ensuring the value, quality, and sustainability of the projects. Apart from this, they also mentor teams, display cross-functional leadership, remove roadblocks, execute projects, achieve lean Six Sigma results, and manage function’s project. 

Six Sigma is an approach towards quality management that can be used for improving the process outputs’ quality. This is done through identification and removal of the causes of errors or defects and minimizing variability in business processes like manufacturing. There is no single, global body that governs the rules of Six Sigma. However, there are multiple organizations offering certifications in the methodology. With these certifications, you will be able to reap several benefits. To get this certification, you need to follow the below-mentioned steps: 

1. Figuring out the management philosophy

  • For this, the first step is considering the requirements of your organization. What management style would benefit it? What is the organizational culture? Is there too much waste and overhead in the supply chain? 
  • The next step is deciding how you can contribute towards optimizing these processes. You might either guarantee quality for ensuring that there are consistent processes with as few variations as possible or you can choose the efficiency of producing a product with as little overhead and waste as possible. 
  • The last step is to determine whether to go for Six Sigma or lean Six Sigma certifications. Use your management philosophy for this. With Six Sigma, you will be defining waste as a variation of the business processes. This certification is for professionals who want to work with a consistent process. Lean Six Sigma is based on both lean and Six Sigma methodology. In this approach, waste is non-value-added entity to the finished product. If you prefer efficiency, you should go for this certification.

2. Deciding the Six Sigma certification level that is best suited for you 

  • This requires you to have an understanding of your role in the organization. Before you select the level, you need to figure out your role. Are you the manager of a project? Are you assistant to the project manager? Does your work involve more than just being a part of the team using the Six Sigma? This will help in determining the certification level you need. 
  • Next, you need to start considering your career goals. You need to know if you want to get involved in project management in the future or not.  
  • The last step is selecting the level of Six Sigma certification. There are 4 levels: Yellow, Green, Black, and Master Black Belt. 
  •  Yellow Belt is for those who will be supporting Green Belts and Black Belts. They need to have a basic knowledge of the Six Sigma process. 
  • Green Belt is for professionals working closely with Black Belts. The primary responsibility of a Green Belt is collecting data. They are also working outside a Six Sigma project. 
  • Black Belts are the project managers who guide and supervise the Yellow Belts and Green Belts. They are working full-time on the Six Sigma project. 
  • Master Black Belts are experts in the field of Six Sigma. The play a role when the team is facing an unexpected turn and a correction in project course is required. 

3. Getting Certified

  • The first step in this is selecting the right training program. Since you will be needing classroom instructions, start by locating training classes that are near you. Then talk to people with Six Sigma certification about their programs and experiences. Enroll in the one with positive recommendations. Next, look for the programs accredited by the organization. Remember that there is no standard body defining Six Sigma.
  • The next step is enrolling in the training program. Start studying rigorously and put in a lot of class time. 
  • Next step is taking the written test. It will prove that you have learned whatever there is to know about Six Sigma. The duration of the exam (in hours) for different accrediting bodies is as mentioned: 

Accrediting bodies

  • The last step is completing the assigned projects using the Six Sigma methodology. Make sure that you are putting your learning into practice. 

For getting Six Sigma certified, a candidate needs to demonstrate their competency by passing a written certification exam. Almost all the certification bodies provide training for the exam, which includes study materials. For Six Sigma certification, you can select one of the following certification bodies:  

1. ASQ Certifications

The ASQ or the American Society for Quality certification program offers 18 different certifications including the yellow, green, black, and master Black Belt certifications. There are 14 other certifications offered by ASQ that are specific to different job roles. ASQ offers membership to candidates at a price ranging from $29 to $159 every year. This depends on whether you are joining at the student level, associate level, or full level. Members of ASQ save a lot of money on certifications.  

2. IASSC Certifications

The primary focus of these certifications is the lean Six Sigma. It is a combination of the manufacturing processes of lean and principles of the Six Sigma approach. You can find all the topics of the IASSC exams in the IASSC Lean Six Sigma Body of Knowledge™ . For the Lean Six Sigma certification program, IASSC offers three certifications, Yellow, Green and Black Belt. For this certification, you don’t need to have any project or work experience as a certification requirement. They do not provide any official training and all you need to do is pass the written exam to get the certification.  

3. Others

There is a Council for Six Sigma Certification that is responsible for maintaining the Six Sigma Body of Knowledge for Black, Green, and Yellow belts. It also has the authority of accrediting organizations for administering certifications. There are some other organizations offering training and certifications for Six Sigma like Villanova University and Six Sigma Certification Tulsa. 

To get the Six Sigma belts, you need to follow the below certification process.  

1. Selecting the accreditation body

There is no official body that conducts the training and certification exam for Six Sigma. There are several organizations providing guidelines, training and certifications for Six Sigma. But, there are two accrediting bodies that are recognized by the top global enterprises.

The American Society for Quality (ASQ) is one such organization that makes sure that the training it provides and the certification exam it conducts are according to the industry standards. It is best to take the Six Sigma training from the courseware that is ASQ accredited. There is no accreditation for Lean Six Sigma in ASQ.

Apart from ASQ, there is the International Association of Six Sigma Certification (IASSC) that accredits the courseware for Six Sigma and lean Six Sigma.  

2. Selecting the training partner

Whether you select the training for Six Sigma and lean Six Sigma, you will have to study about the complex tools and methods. With so many options available, it is important that you need to select the right standard, recognized training. Here are the aspects that need to be considered for evaluating the right training partner: 

  • Accreditation - You need to select an organization accredited by IASSC or ASQ. It depends on the track you are selecting, Six Sigma or lean Six Sigma. This will ensure that the training that you are going through is according to the standards of the accrediting body. 
  • Mode of Delivery - You have to choose an organization providing training suited to your needs and offering different delivery options. There are several options like classroom, online self-learning, and instructor-led online classes. This will provide you with the flexibility of selecting the right fit suited to your needs.  
  • Duration - There are some courses that are condensed so that they can be finished in one or two days. Some other courses are more elaborate, and are spread through 4 to 5 days. You need to look through your experience and level of preparation for selecting the most appropriate training for your needs.  

3. Giving the certification exam

Now, you need to select the Six Sigma certification according to your role and experience. 

Here are the benefits of getting Six Sigma certification for individuals:  

  • You will help the organization by eliminating defects and errors and reducing risk. A Six Sigma certification and knowledge of project management software such as Celoxis will help you become indispensable to your organization to identify and eliminate errors. 
  • You will be able to sustain quality improvement and improve business processes. After you have completed the Six Sigma course, you will be analyzing the business and manufacturing processes of the company and taking steps for improving them. Also, you will be responsible for conducting the review of current practices and understanding how quality performance can be impacted. Also, with this certification, you will be achieving a level of sustained quality improvement. There will be monitoring processes ensuring that there is as little deviation as possible from the mean. You will be implementing corrective measures for reeling in a project. 
  • The certification will enhance your value in the industry. You can use the techniques of Six Sigma for aerospace, banking, telecom, electronics, IT, finance, marketing, HR, and many more.

ASQ calculates the passing score through its Standards for Educational and Psychological Testing. They use a procedure named cut score study for calculating the passing grade. A new cut point is established every time there is a creation or revision in the Body of Knowledge. A panel of matter experts is created who set the performance standard for the exam. With the help of consensus, they build a set of characteristics that is expected of a borderline candidate.

The performance expectations are clearly stated. After the characteristics are determined, they are used as a guide for rating every question in terms of how many borderline candidates out of 100 will be able to get the right answer. The result of this study is presented to the board. Once the board approves the raw cut score point, it is converted to scale score.

For selecting the right Six Sigma certification, you must know the difference between all of them and see which one suits your needs the best: 

  • White belt 

This certification has training lasting for a few hours and includes the fundamental concepts and basic vocabulary of the methodology. This is a certification that is well suited for all the employees working in an organization that practices Six Sigma. It is basically an overview training level. This level is only offered by CSSC and is for professionals who want to display their knowledge of history, definition and structure of quality improvement. They must be aware of people involved in the implementation of six sigma.  

  • Yellow belt 

This certification is for professionals working as a member of the Six Sigma team. The training takes a couple of days to finish. A yellow belt would by virtue of knowledge know more than white belts, but less than Green Belts. Yellow belts have the knowledge to be a functional and productive team member of a Six Sigma team working on a Six Sigma project. However, the education is not enough to lead a Six Sigma project. 

It is offered by ASQ, IASSC as well as CSSC. According to ASQ, this certification advances the potential of methodologies and tools of six sigma. It is aimed at entry-level employees who have an interest or a small role working with six sigma. For IASSC yellow belt certification, you need to have knowledge of the DMC (Define, Control, and Measure) phases defined by the IASSC Lean Six Sigma Yellow Belt Body of Knowledge™  .  

  • Green Belt 

Professionals with a Green Belt are trained for solving problems related to processes. The training lasts about 10 days. Most of these professionals are process leaders or working within processes like employees in the manufacturing line or accounting group. They are responsible for implementing Six Sigma projects in their department. They are also improving processes. As a Green Belt, they lead the members through project tool set and framework, reduce defects, and evaluate solutions. They are supported by a Black Belt who is mentoring and coaching them.

A Green Belt certification will do wonders for you if you want to move up the corporate ladder. You can get this certification through ASQ, IASSC, and CSSC. Since a green belt works under the leadership of a black belt, they must have the skills of analyzing and solving quality problems. The ASQ certification is for individuals with knowledge of processes and tools of six sigma. CSSC offers Green belt certification in two levels. The standard certification is for candidates with knowledge of the DMAIC model. The advanced certification will help demonstrate your ability to work as a trained team member with a specific function. With this, you will be able to work in a defined six sigma project without much supervision of a Black Belt.  

  • Black Belt 

These are professionals who go through 20 days of training to learn solving process problems. They are highly trained in the methods and tools of lean and Six Sigma. Black Belts are responsible for implementing improvement projects that are strategically important and complicated. They are cross-functional and need leadership skills and significant data. They also mentor and coach the assigned Green Belts. With a Black Belt certification, you will be able to deliver projects with financial benefits to the enterprise.

There are several companies who want Black Belt as a prerequisite for the managers because they will be able to look into processes and defects. Offered by ASQ, IASSC, and CSSC, this certification is for candidates who understand and can explain the principles and philosophies of six sigma. For CSSC, there are three levels of Black Belt certification. The first level is the standard level for which you need to cover the Body of Knowledge. For level II, you need to execute a DMADV or DMAIC project for demonstrating your knowledge. The Level III requires submission of one more approved project where you have displayed understanding of principles and philosophies of six sigma.  

  • Master Black Belt 

This is the most comprehensive training for the most skilled professionals of Six Sigma and lean. They have expertise in leadership, root cause analysis, strategic management, and facilitation. They also have training in design for Six Sigma. 

They work in change management leading a project and group to successful completion. They create a strategic direction, remove a roadblock that the Green Belts or Black Belts are facing, and overseeing and delivering training of other employees working in the organization. A master Black Belt can coach between 2 to 10 Black Belts simultaneously. You need this certification if you want a career in lean Six Sigma and quality. You can get this certification through ASQ and CSSC. IASSC does not offer Master Black Belt certification. 

When you are going for the Six Sigma certification, you need to select the one that is most respected, recognized and capable. There are several vendors, industry organizations, individual corporations, and for-profit schools that are offering Six Sigma certifications. The certification is available in three forms. The first one is the main bodies like IASSC, ASQ, etc. The second one is a university like Villanova and the last one is in-house certifications from different organizations. All of these are trusted options that ensure that the expectations and standards are met.   

The leading contenders in the field of Six Sigma are IASSC and ASQ. For testing you, they use Body of Knowledge. Both the certification bodies focus on some subjects more than others.  

As long as the university is accredited, the certification they provide would also be of value. If the university is providing training with no proper accreditation, the certification will be of no use. Some accredited universities also offer online training for Six Sigma.  

There are some businesses that consider Six Sigma as an important part of their success. So, they offer in-house certification for their employees. GE and Cummins are some of such enterprises. They want their employees to have the required standard and experience.

Six Sigma has a hierarchy of certification: Six Sigma Yellow Belt, Six Sigma Green Belt, Six Sigma Black Belt and Six Sigma Master Black Belt. This hierarchy is created to help candidates understand the increasing scope and depth of six sigma tools and applications. However, if you think that you understand the tools and their applications very well, you may skip a level.

Statistics are an important part of Six Sigma as they help in determining the extent of defects. However, Six Sigma is more than just statistics. It is about creating a culture in an organization that demands perfection. It gives the employees tools that can pinpoint gaps in performance and help them in making necessary improvements through data-driven, problem-solving methods.

The basics of Six Sigma are:

  • Philosophy - The process inputs determine the quality of the output and control it.
  • Focus - Improving business processes.
  • Methods - DMAIC (Define, Measure, Analyze, Improve, and Control) or DMADV (Define, Measure, Analyze, Design, Verify).
  • Measure of Success - When defects are reduced to 3.4 over one million opportunities.
  • Drive - People who have a hunger for constant improvement.

There are two core methodologies of Six Sigma:


  • Defining the system or process that must be improved.
  • Measuring and collecting data on relevant aspects of the process.
  • Analyzing collected data for determining the cause and effect relationships and uncover the causes that affect the performance of the process.
  • Improving the process and developing a future-state process using the data analysis results.
  • Controlling the improved future-state process through control systems.


  • Defining and elaborating design goals that are consistent with the needs of the customers.
  • Measuring the characteristics, production process parameters, potential risks, and capabilities of the new product or process.
  • Analyzing data collected from the last step for developing alternative process designs and products.
  • Designing the best process configuration or product based on the analysis results.
  • Verifying that the design is functional by conducting pilot runs and assisting the process owner during full-scale implementation.

Six Sigma is a set of management techniques and tools created for improving business by reducing the possibility of error. Its concept is a data-driven approach that uses statistics to eliminate defects.

The core Six Sigma principles are:

  • Focus on the customers
  • Understand how the work is happening
  • Make the processes flow smoothly
  • Concentrate on value and reduce waste
  • Remove variation to stop defects
  • Get buy-in from the team
  • Make scientific and systematic efforts

This is an obvious question that any aspirant would have. Considering the different course offerings, Green Belt certifications offered by some facilities require a minimum of three years’ experience with DMAIC phases. However, some facilities do allow you to begin training straight away. 

There is work-at-home program requiring 30-hour online class time along with the completion of assignments as well as intense onsite 2-week programs. With both these Green Belt training, the basics of DMAIC are covered, along with learning tools of Six Sigma like Pareto and Gantt charts, data collection and organizational skills. 

After the completion of training, the candidate has to attempt a Six Sigma Green Belt certification exam. The candidate receives the certification on passing the examination. 

As far as the difficulty of the exam is concerned, it actually is not that hard. You may face difficulty in managing time if you have a hectic life. It is all about allocating sufficient time for preparation of your exam while also parallelly managing other activities. 

ASQ knows that it is very important that you get the prompt notification of the results of your certification exam. The exam results are confidential. So, they will not be given over the phone. Also, if you want the information regarding your exam results to be given to third-parties, you will need to give a written request. All the candidates who have passed the ASQ Green Belt exam will have their details in the voluntary Certification Registry. Now, there are different methods to get the results for the computer based and paper based tests.  

For the computer based tests, you will be given your test results on the screen you are using for your exam at the prometric testing center. Also, your test results will be sent to you through a follow-up email from Prometric as well. The only exception for this is the exams piloting the new BoK or MBB. You will be receiving your official ASQ results via the exam notification within 7 days. Along with this, there will also be a short survey with questions regarding your exam experience. The results for the pilot exams, MBB and exams with updated BoK will be sent through email in about 4 weeks.   

For the paper based test, your completed paper-exam documents will be mailed to the ASQ by your exam proctor. After they have been graded, you will be receiving the exam results of your Green Belt exam in an email in about 2 weeks. Along with that, there will also be a short survey asking questions regarding your experience in the exam. It will take about 4 weeks to get the results for the pilot exams, MBB, and exams with updated BoK.

If you have taken the IASSC Certified Lean Six Sigma Green Belt Exam™, you will be provided your results through email within 1 to 2 days after giving the exam. If you pass the exam, you will be getting a certification from the IASSC. 

When the validity of a certification expires, the candidate is required to get recertified. Recertification is important, when it comes to professional credentials. Not only does recertification ensure standard integrity, but also serves as an exhibit of the regard a professional has for the best practices associated with the certification. It is proof of ongoing professional competence of individuals. It adds to the ongoing accomplishment, while also demonstrating to peers and employers proof of skill and knowledge maintained for being proficient as an active Lean Six Sigma Practitioner. 

IASSC Certified Professionals are recognized by The International Association of Six Sigma Certification. Once a professional receives the certification, a Current status is granted for three years. After that, an Elapsed status will be applicable unless successful recertification of the individual is completed. 

The IASSC Recertification Green Belt Exam is a closed book, 1.5-hour long, proctored exam consisting of 50 questions. A professional should achieve a score of at least 70% to get recertified. The recertification fee is $175. 

ASQ also requires recertification every three years to make sure the required level of knowledge is maintained. However, certifications like the Six Sigma Green Belt (CSSGB) are lifetime certifications. This means they don’t have any recertification requirements. 

In case you fail to achieve a passing score for your lean Six Sigma Green Belt exam on your first attempt, it won’t be possible to sit for the same exam for the second time within 2 weeks of the first sitting. It is not possible to undertake a third sitting within 3 months of the first sitting. Subsequently, there must be a minimum duration of three months between further sitting and sitting you failed most recently in. 

An IASSC exam voucher is valid only for a single attempt at an examination. In case you do not pass, you will be required to purchase another examination voucher for retaking it. 

Only a single retake attempt is allowed for ATA application candidates. ATA candidates failing the initial exam attempt and then the subsequent retake has to wait for 6 months after their original application for reapplying for the accreditation. 

  • Computer Based Testing: In case you fail to achieve a passing score on your CBT (Computer Based Testing) exam, you can reapply and then retake the CBT exam at the test window available next. It is not possible to retake examination within same test window as your previous exam. 
  • Paper and Pencil Testing: Reapplying and retaking the paper exam is possible at a test date that is available next. 

The Six Sigma Green Belt certification is in high demand since companies from across the world are looking to cut down on costs, eliminate waste, and improve processes. A professional certified with Six Sigma Green Belt would be able to implement Six Sigma methodologies and tools for preventing defects and increasing customer satisfaction.

Six Sigma

Six Sigma is a data-driven and disciplined approach and a methodology for continuous improvement that uses statistics to eliminate defects in a product, service or a process. Developed by Bill Smith and Motorola in the 1980s, the approach was created on the basis of the fundamentals of quality management. It was popularised in the 1990s when Jack Welch adopted the methodology at General Electric (GE), and it was found to be very effective in establishing high-quality benchmarks in product management processes. The approach was created after studying the methods taught by Ronald Fisher, Walter Shewhart, and W. Edwards Deming. Today, there are hundreds of companies across the globe that are using Six Sigma for their business.  

The sigma here is representing the population standard deviation. It is the variation measure in a dataset that was collected regarding the process. For all the defects that are defined using specification limits that separates good and bad outcomes of a process, there is a Six Sigma process with a mean which is exactly six standard deviations away from the nearest limit of the specification. Because of this, there is enough buffer between the specification limits and the process of natural variation. 

For many organizations, Six Sigma is a quality measure to strive for perfection. More than often, organizations use customized names for the Six Sigma approach such as Customer Perfection, Zero Defects, or Operational Excellence. Whatever the name, the underlying use of this approach is to eliminate defects from all processes, including transactional and manufacturing of products or services. 

There are several definitions proposed for the Six Sigma approach:  

  1. Philosophy - When you take a look at the Six Sigma approach philosophically, you will notice that all the views work together as processes that can be used for defining, measuring, analyzing, improving, and controlling. For these processes to work, you will need inputs (x) that will be producing outputs (y). For controlling the outputs, you need to control the inputs. The equation for expressing this is y=f(x). 

  2. Set of tools - For the Six Sigma approach, specific quantitative and qualitative tools and technologies are used for driving the process improvement. Different Six Sigma professionals have varying views on the tools making up the Six Sigma set. Some common tools used for the approach are process mapping, control charts, statistical process control (SPC), and failure mode and effects analysis (FMEA). 

  3. Methodology - This view of the Six Sigma approach takes into account the underlying, rigorous approach called DMAIC (Define, Measure, Analyze, Improve, and Control). In this, all the steps that a Six Sigma Practitioner must follow have been defined. It starts with identification of the problem and ends with implementing a long-lasting solution. There are several other methodologies of Six Sigma that are currently in use. However, DMAIC is the most recognized and adopted. 

  4. Metrics - The quality performance of the Six Sigma approach is 3.4 defects per million opportunities. This also takes into account the shift of 1.5-sigma in the mean. 

All these views of the Six-Sigma approach share the following threads:  

  • A management environment supporting the initiatives of the Six Sigma as a business strategy. 
  • Emphasizing on the DMAIC approach to solve problems that include defining, measuring, analyzing, improving and controlling.
  • Using the teams assigned with well-defined projects. They have a direct impact on the bottom line of the organization. 
  • All the levels should be trained in statistical thinking. The key people must be provided with extensive training in project management and advanced statistics. A “Black Belt” will be designated to all the key people with this training. 

The term “Lean Six Sigma” is now a  very commonly used term. Lean and Six Sigma are different approaches. But, both approaches are required for attaining positive results in improving the business. Lean approach is used for driving out waste like non-value added procedures and processes, and promoting work flow and standardization. The primary focus of the Six Sigma approach is to reduce process variation and enhance process control. A Six Sigma practitioner should be familiar with both approaches.  

Lean Six Sigma is a data-driven, fact-based philosophy that is used to improve the process by valuing preventing defect over detecting defect. It reduces waste, variation and cycle time by driving bottom-line results and customer satisfaction. It also creates a competitive advantage by promoting the use of workflow and standardizations. You can apply this approach to any place where waste and variation exist. Every employee of the organization must be involved in this.  

Both these approaches provide customers with the best cost, quality, and delivery options along with a new nimbleness. Both the disciplines overlap a lot and serve a common purpose with some minor differences:  

  • Six Sigma focuses on reducing variation while Lean focuses on reducing waste.
  • Six Sigma uses tools like statistical data analysis, hypothesis testing, and designing experiments for achieving its goals. Lean uses much less technical tools like workplace organization, kaizen, and visual controls. 

For the best implementation, you need to start with a lean approach to make the workplace as effective and as efficient as possible. Then, you have to use value stream maps for better understanding. If the problem of the process still persists, you can apply technical statistical tools of Six Sigma.

There are multiple options available for Six Sigma certification. Six Sigma and Lean Six Sigma are some of them. Both of them are methodologies of process improvement that are used for accomplishing similar tasks. So, often, they are used in conjunction. They began in the manufacturing sector and now, they have found their ways in other industries as well.   

The aim of the Six Sigma methodology is eliminating inefficiency and waste. This increases customer satisfaction as you are delivering according to the expectations of the customer. It is a disciplined process focused on development and delivery of near-perfect services and products. The idea behind this approach is that after measuring the number of defects, you can figure out how they can be eliminated. Its aim is to get close to zero issues in the product.  

The lean approach is focused on providing optimum performance with the least amount of energy and effort. This is done through supply of product according to the needs of the customer in just the right price and the right amount with minimum materials, workspace, time, equipment, and labor resource. It focuses on removing all the unnecessary waste from the process and producing output of high quality.
