Six Sigma is a business management strategy that was initially developed by Motorola in the 1980s and is used by many Fortune 500 companies today. It is primarily used to identify and rectify errors in a manufacturing or business process.
The Six Sigma system uses a number of quality methods and tools that are used by Six Sigma trained professionals within the organization. The DMAIC problem-solving method can be used to help with any issue that arises, usually by professionals in the organization who have reached the "green belt" level.
The DMAIC Method
The DMAIC problem-solving method is a roadmap that can be used for any projects or quality improvements that need to be made. The term DMAIC stands for the five main steps in the process: Define, Measure, Analyze, Improve, and Control.
- Define: It is important in Six Sigma to define the problem or project goals. The more specific the problem is defined, the greater the chance of obtaining measurements and then successfully completing the project or solving the problem. The definition should describe the issue accurately with numeric representation. For example, “damaged finished goods from the production line have increased 17 percent in the last three months." The definition of the problem or project should not be vague, such as, “quality has fallen.” As part of the definition stage, the scope of the project or issue should be defined, as well as the business processes involved.
- Measure: When the project or problem has been defined, decisions should then be made about additional measurements required to quantify the problem. For example, if the definition of the problem is “damaged finished goods from the production line have increased 17 percent in the last three months,” then additional measurements might need to be looked at. This includes what finished goods are being damaged, when they are being damaged, and the level of damage.
- Analyze: Once the measuring stage has defined the additional measurements, the data is then collected and analyzed. At this point, it is possible to determine whether the problem is valid or whether it is a random event that does not have a specific cause that can be corrected. The data that has been collected can be used as a base level to compare against measurements after the project has been completed to ascertain the success of the project.
- Improve: After measurements have been taken and analyzed, possible solutions can then be developed. Test data can be created and pilot studies launched to find which of the solutions offers the best improvements to the issue. The team should also look at the results to ensure that there are no unanticipated consequences to the selected solution. When the most appropriate solution is selected, then the team can develop an implementation plan and a timeline for the completion of the project.
- Control: After the implementation of the solution or project, a number of controls must be put in place so that measurements can be taken to confirm that the solution is still valid and to prevent a recurrence. The control measurements can be scheduled for specific dates, e.g., monthly, daily, and yearly. The solution should also be well documented and any other related process documentation updated.
The DMAIC problem-solving method can produce significant improvements for an organization that is using the Six Sigma methodology and tools. The method offers a five-step plan that gives organizations a roadmap to follow so that issues can be resolved using a structured methodology.

Six Sigma Basics: DMAIC Like Normal Problem Solving
Published: February 26, 2010 by Chew Jian Chieh
What is the usual way most people go about solving problems? Most people and organizations consciously or unconsciously use this method, as illustrated in Table 1 below.
This is not a bad method, provided what one thinks is causing the problem is really causing the problem. In this case, if a person is fat simply because they do not exercise enough and eat too much, then by exercising and eating less, they should weigh less. And if they do lose weight after taking such action, then the theory is validated. People solve a fair number of problems in this manner – using conventional wisdom and gut theories that also happen to be correct. In those cases, there is little need for Six Sigma – it is just a waste of time. Just do the above.
How Six Sigma Problem Solving Is Different
How is the Six Sigma problem-solving methodology different? Actually it is really not so different from how people normally go about solving day-to-day problems, except in Six Sigma, nobody knows what is really causing the problem at the beginning of the project. And because all attempts to solve the problem in the past have failed, largely because conventional wisdom and gut theories were wrong about the cause of that problem, people conclude that the problem cannot be solved.
These types of problems are really the best candidates for Six Sigma. The Six Sigma DMAIC methodology differs from conventional problem solving in one significant way. There is a requirement for proof of cause and effect before improvement action is taken. Proof is required because resources for improvement actions are limited in most organizations. Those limits preclude being able to implement improvement actions based on 100 hunches hoping that one hits the mark. Thus, discovering root causes is at the core of the methodology.
Here are the steps in the DMAIC process:
- Define phase: Understand what process is to be improved and set a goal.
- Measure phase: Measure the current state.
- Analyze phase: a) Develop cause-and-effect theories of what may be causing the problem; b) Search for the real causes of the problem and scientifically prove the cause-and-effect linkage
- Improve phase: Take action.
- Control phase: a) Measure to verify improvement has taken place; b) Take actions to sustain the gains.
Using a More Mathematical Language
The above steps can be phrase in another way – using more mathematical language (Table 2). (This kind of mathematical language should not put anyone off. If it is a concern initially, a person just needs to remember than whenever a Y shows up in any sentence, just replace it with word “effect,” or the phrase “outcome performance measure.” And whenever an X shows up , just replace it with the word “cause.”)
The key assumption in Six Sigma is this: If the true causes of any problem can discovered, then by controlling or removing the causes, the problem can be reduced or removed. Now is that not just common sense?
A Series of Common Sense Questions
In summary, Six Sigma DMAIC methodology is really just a series of common sense questions that one asks in order to solve any problem and eventually sustain the gains that come from solving the problem.
- Define: What is the Y that is not doing well?
- Measure: What is Y’s current performance?
- Analyze: What are the potential Xs? What are the real Xs?
- Improve: How can the real Xs be controlled or eliminated?
- Control: How can the Xs continue to be controlled to sustain the gains in Y?
Six Sigma’s DMAIC methodology is nothing but a search for the real causes of problems. With this understanding, what remains for those learning Six Sigma are the various tools and techniques used to answer these questions.

DMAIC – The 5 Phases of Lean Six Sigma
DMAIC is the problem-solving approach that drives Lean Six Sigma . It’s a five-phase method—Define, Measure, Analyze, Improve and Control—for improving existing process problems with unknown causes. DMAIC is based on the Scientific Method and it’s pronounced “duh-may-ik.”
To build your understanding of the method, and help you apply it to solve process problems, we’ve broken down the DMAIC Phases for you.
Before Starting DMAIC: Select a Good Project
The focus of any process improvement effort is selecting the right project. Good candidates for improvement will set you up for success with DMAIC. Here are 4 key guidelines:
- Choose an obvious problem within an existing process
- Choose something that would make a difference but would not be overly complex to address— Meaningful but Manageable
- Make sure there is potential to reduce lead time or defects while resulting in cost savings or improved productivity
- Check if you can collect data about the selected process—you want to achieve Measurable improvement
Once you’ve selected a good project, you and your improvement team can apply DMAIC to dig into process issues and deliver quantifiable, sustainable results.

What problem would you like to fix? Define is the first phase of the Lean Six Sigma improvement process. During this phase the project team drafts a Project Charter , plots a high-level map of the process and clarifies the needs of the process customers . By conducting Process Walks and talking to process participants they begin their journey of building their process knowledge. Before moving on to the Measure Phase, the team refines their project focus and ensures they’re aligned with the goals of organizational leadership.

The Easy Guide to Solving Problems with Six Sigma DMAIC Method
The most commonly used methodology in Six Sigma is the DMAIC process. Many use it to solve problems and identify and fix errors in business and manufacturing processes.
In this post, we will look at how to use the DMAIC process to solve problems. You will also find useful and editable templates that you can use right away when implementing DMAIC problem-solving in your organization.
What are 5 steps for Six Sigma?
DMAIC is a data-driven method used to systematically improve the process. The approach aims to increase the quality of a product or service by focusing on optimizing the process that produces the output. This way DMAIC seeks to provide permanent solutions when it comes to process improvement.
DMAIC Process and Problem-Solving
Following we have listed down the 5 phases of the DMAIC process along with the steps you need to take when using it to solve problems. Different tools for each phase is provided with editable templates.
Step 1: Define the Problem
So there’s a problem that affects your customer or your company processes. In this first step of the DMAIC problem solving method , you need to focus on what the problem is and how it has affected you as a company.
There are a few steps you need to follow in this phase.
• Create a problem statement which should include a definition of the problem in quantifiable terms and the severity of the problem.
• Make sure necessary resources such as a team leader and competent team members, and funds etc. are available at hand.
• Develop a goal statement based on your problem statement. It should be a measurable and time-bound target to achieve.
• Create a diagram which will provide the team with a high-level overview of the process (along with its inputs, outputs, suppliers, and customers) that is being analyzed. You can also use a value stream map to do the same job.
• Try to understand the process in more in-depth detail by creating a process map that outlines all process steps. Involve the process owners when identifying the process steps and developing the map. You can add swimlanes to represent different departments and actors responsible.
Step 2: Measure the Problem
In this step, you should measure the extent of the problem. To do so you need to examine the process in its current state to see how it performs. The detailed process map you created in the ‘Define’ phase can help you with this.
The baseline measurements you will need to look into in this phase, are process duration, the number of defects, costs and other relevant metrics.
These baseline measurements will be used as the standards against which the team will measure their success in the ‘Improve’ phase.
Step 3: Analyze the Problem
The analyze phase of the DMAIC process is about identifying the root cause that is causing the problem.
• Referring to the process maps and value stream maps you have created, further, analyze the process to identify the problem areas.
• Visualize the data you have collected (both in the ‘Measure’ phase and the analyze phase) to identify signs of problems in the processes.
• Use Pareto charts, histograms, run charts etc. to represent numerical data. Study them with team leaders and process owners to identify patterns.
• With the results of your process analysis and your data analysis, start brainstorming the root causes of the problem. Use a cause and effect diagram/ fishbone diagram to capture the knowledge of the process participants during the session.
• Using a 5 whys diagram, narrow down your findings to the last few causes of the problem in your process.
Step 4: Improve (Solve the Problem)
In this phase, the focus is on mitigating the root cause identified and brainstorming and implementing solutions. The team will also collect data to measure their improvement against the data collected during the ‘Measure’ phase.
• You may generate several effective solutions to the root cause, but implementing them all would not be practical. Therefore, you will have to select the most practical solutions.
To do this you can use an impact effort matrix . It will help you determine which solution has the best impact and the least effort/ cost.
• Based on different solutions, you should develop new maps that will reflect the status of the process once the solution has been applied. This map is known as the to-be map or the future-state map. It will provide guidance for the team as they implement changes.
• Explore the different solutions using the PDCA cycle and select the best one to implement. The cycle allows you to systematically study the possible solutions, evaluate the results and select the ones that have a higher chance of success.
Step 5: Control (Sustain the Improvements)
In the final phase of the DMAIC method , the focus falls on maintaining the improvements you have gained by implementing the solutions. Here you should continue to measure the success and create a plan to monitor the improvements (a Monitoring plan).
You should also create a Response plan which includes steps to take if there’s a drop in the process performance. With new process maps and other documentation, you should then proceed to document the improved processes.
Hand these documents along with the Monitoring plan and the response plan to the process owners for their reference.

DMAIC Model | The 5 Phase DMAIC Process to Problem-Solving
- 4 mins to read
Summary: An Introduction to DMAIC
Dmaic – the dmaic model.
The DMAIC model remains the core roadmap for almost all Lean Six Sigma problem-solving approaches that drive quality improvement projects. It is used to ensure a robust problem-solving process is followed to give the best chance of the best solution being found.
A note about the structure and the approach used in this article.
Our approach to DMAIC follows Quentin Brook’s book “Lean Six Sigma & Minitab” which for anyone wishing to study Lean Six Sigma is a must for the Green Belt Course and the Black Belt Course .
What is the dmaic model.
DMAIC is short for: Define, Measure, Analyse, Improve and Control. These are the key phases that each project must go through to find the right solution.
As you can quickly see from the 5 DMAIC phases they follow a logical sequence as we will go through in more detail below. But they also make sure you do not try to jump to implementing a solution before you have properly, defined and measured what you are going to be an improvement.
We all love to jump to solutions, but the DMAIC problem-solving structure helps us have a more rigorous approach so that we do not short cut the process and perhaps miss the best solution or perhaps implement the wrong solution as well. It can help companies better structure their problem-solving approaches and be more robust in their approach.
DMAIC – The 5 DMAIC Process Phases
The phases throughout the DMAIC model have and can be broken down in many different ways. One of the best approaches we have found is from Opex Resources.
DMAIC Define Phase
The purpose of the Define phase is ultimately to describe the problems that need to be solved and for the key business decision-makers to be aligned on the goal of the project.
All too often, teams have identified solutions without actually defining what it is they will actually be trying to do or perhaps not do. This can lead to internal confusion and often solutions which completely miss the business requirements and needs.
- Define the Business Case
- Understand the Consumer
- Define The Process
- Manage the Project
- Gain Project Approval
DMAIC Measure Phase
In the measure phase, the goal is to collect the relevant information to baseline the current performance of the product or the process. In this stage, we want to identify the level of “defects” or the errors that go wrong and use the baseline to measure our progress throughout the project.
The key goal of this phase is to have a very strong and clear measure/baseline of how things are performing today so that we can always monitor our progress towards our goals. We need to understand our cycle times , process times, quality metrics.
Many projects are delivered without clear benefits being shown because the team never fully baseline the current status before making changes.
The Measure phase can be broken down into 5 key areas:
- Develop Process Measures
- Collect Process Data
- Check the Data Quality
- Understand Process Behaviour
- Baseline Process Capability and Potential

We can’t solve problems by using the same kind of thinking we used when we created them” Albert Einstein Tweet
DMAIC Analyse Phase
The goal of the Analyse phase is to identify which process inputs or parameters have the most critical effect on the outputs. In other words, we want to identify the root cause(s) so that we know what critical elements we need to fix.
During this phase, the teams need to explore all potential root causes using both analytical approaches, statistical approaches or even graphical tools such as VSM’s and Process maps to uncover the most important elements which need to be changed/fixed.
The Analyse phase can be broken down into:
- Analyse the Process
- Develop Theories and Ideas
- Analyse the Data
- and finally, Verify Root Causes
DMAIC Improve Phase
The goal of the improvement phase is to identify a wide range of potential solutions before identifying the critical solutions which will give us the maximum return for our investment and directly fix the root cause we identified.
During this phase, the team brainstorm, pilot, test and validate potential improvement ideas before finally implementing the right solutions. With each pilot, the team can validate how well it improves the key measures they identified back in Define and Measure. When the team finally roll out the solution, the results should be seen if the right solution has been found and implemented correctly.
The Improve phase can be broken down into:
- Generate Potential Solutions
- Select the Best Solution
- Assess the Risks
- Pilot and Implement
DMAIC Control Phase
The final part of the DMAIC Model is the Control phase where we need to ensure that the new changes become business as normal and we do not revert to the same way of working as before.
During this phase, we want to ensure that we close the project off by validating the project savings and ensuring the new process is correctly documented. We also need to make sure that new measures and process KPI’s are in place and, finally that we get the business champion to sign off on both the project and the savings. We may need to redesign the workplace following the 5S principles .
The Control phase can be broken down into:
- Implement Ongoing Measurements
- Standardise Solutions
- Quantify the Improvement
- Close The Project
The key closing documents of the Control Phase is a Control Plan that documents all the changes and process steps with key risks, standard work instructions and the Project Close-Out document signed by the business owners to accept the change and the validated benefits.
The DMAIC Model vs. A3 Management vs. 8D Problem Solving
The DMAIC model is not the only project management roadmap. Two others which are important is the A3 format which originally comes from Toyota and is very Lean focused and the 8D which draws more of the DMAIC structure but with the 1-page idea of the A3.
Everyone has their own preference but each method is interchangeable. The DMAIC Structure lends its self naturally to a multi-slide Powerpoint presentation. Whereas the A3 is a single-page document which is perfect for internal communication and adding into War Rooms and Control Towers.
What’s important is that every problem-solving approach follows the PDCA (Plan, Do, Check and Act) Scientific Problem Solving format. The reset is just a preference or using the right tool in the right circumstances.

What is six sigma, become a certified quality system manager.
Six Sigma is a set of management tools and techniques designed to improve the capability of the business process by reducing the likelihood of error. Six sigma is a data-driven approach that uses a statistical methodology for eliminating defects, defect reduction and profits improvement.
Digital transformation has become the hottest buzzword of this decade. New technologies and tools are supporting the transformation journey of companies big and small as they compete to get a bigger slice of business in a fast-paced competitive environment. Yet, is it enough to smooth a company's transformative process? Can a standalone technology implementation remove a bottleneck in the production process or support troubleshooting a service design flaw? Although digital transformation fast-tracks a company's growth, it has to be equally supported by management methods of quality control and business transformation.
Keeping in tune with emerging markets and processes, the American company Motorola developed a new concept of quality management process in 1986. Over the years, it has been refined and polished into a sound theory of principles and methods, aimed at business transformation through a clearly defined process. This finished product is Six Sigma. And in this article, we will cover the following topics in detail:
- What is six sigma?
- The 5 key principles of six sigma
- The six sigma methodology
- The six sigma process of business transformation
- Top six sigma techniques
- Top 7 six sigma tools
- Six sigma levels
- Six sigma certification levels
- Various career opportunities and salary aspects
- Top six sigma learning resources
The etymology is based on the Greek symbol "sigma" or "σ," a statistical term for measuring process deviation from the process mean or target. "Six Sigma" comes from the bell curve used in statistics, where one Sigma symbolizes a single standard deviation from the mean. If the process has six Sigmas, three above and three below the mean, the defect rate is classified as "extremely low."

The graph of the normal distribution below underscores the statistical assumptions of the Six Sigma model . The higher the standard deviation, the higher is the spread of values encountered. So, processes, where the mean is minimum 6σ away from the closest specification limit, are aimed at Six Sigma.

The 5 Key Principles of Six Sigma
The concept of Six Sigma has a simple goal – delivering near-perfect goods and services for business transformation for optimal customer satisfaction (CX).
Goals are achieved through a two-pronged approach:
Six Sigma has its foundations in five key principles:

The Six Sigma Methodology
The two main Six Sigma methodologies are DMAIC and DMADV . Each has its own set of recommended procedures to be implemented for business transformation.
DMAIC is a data-driven method used to improve existing products or services for better customer satisfaction. It is the acronym for the five phases: D – Define, M – Measure, A – Analyse, I – Improve, C – Control. DMAIC is applied in the manufacturing of a product or delivery of a service.
DMADV is a part of the Design for Six Sigma (DFSS) process used to design or re-design different processes of product manufacturing or service delivery. The five phases of DMADV are: D – Define, M – Measure, A – Analyse, D – Design, V – Validate. DMADV is employed when existing processes do not meet customer conditions, even after optimization, or when it is required to develop new methods. It is executed by Six Sigma Green Belts and Six Sigma Black Belts and under the supervision of Six Sigma Master Black Belts. We'll get to the belts later.
Fast Track Your Career in Quality Management
The two methodologies are used in different business settings, and professionals seeking to master these methods and application scenarios would do well to take an online certificate program taught by industry experts.
The Six Sigma Process of Business Transformation
Although what is Six Sigma uses various methods to discover deviations and solve problems, the DMAIC is the standard methodology used by Six Sigma practitioners. Six Sigma uses a data-driven management process used for optimizing and improving business processes. The underlying framework is a strong customer focus and robust use of data and statistics to conclude.
The Six Sigma Process of the DMAIC method has five phases :
Each of the above phases of business transformation has several steps:

Six Sigma Techniques
The Six Sigma methodology also uses a mix of statistical and data analysis tools such as process mapping and design and proven qualitative and quantitative techniques, to achieve the desired outcome.
Fig: Key Six Sigma Techniques in use
Brainstorming
Brainstorming is the key process of any problem-solving method and is often utilized in the "improve" phase of the DMAIC methodology. It is a necessary process before anyone starts using any tools. Brainstorming involves bouncing ideas and generating creative ways to approach a problem through intensive freewheeling group discussions. A facilitator, who is typically the lead Black Belt or Green Belt, moderates the open session among a group of participants.
Root Cause Analysis/The 5 Whys
This technique helps to get to the root cause of the problems under consideration and is used in the "analyze" phase of the DMAIC cycle.
In the 5 Whys technique, the question "why" is asked, again and again, finally leading up to the core issue. Although "five" is a rule of thumb, the actual number of questions can be greater or fewer, whatever it takes to gain clarity.
Voice of the Customer
This is the process used to capture the "voice of the customer" or customer feedback by either internal or external means. The technique is aimed at giving the customer the best products and services. It captures the changing needs of the customer through direct and indirect methods. The voice of the customer technique is used in the "define' phase of the DMAIC method, usually to further define the problem to be addressed.
The 5S System
This technique has its roots in the Japanese principle of workplace energies. The 5S System is aimed at removing waste and eliminating bottlenecks from inefficient tools, equipment, or resources in the workplace. The five steps used are Seiri (Sort), Seiton (Set In Order), Seiso (Shine), Seiketsu (Standardize), and Shitsuke (Sustain).
Kaizen (Continuous Improvement)
The Kaizen technique is a powerful strategy that powers a continuous engine for business improvement. It is the practice continuously monitoring, identifying, and executing improvements. This is a particularly useful practice for the manufacturing sector. Collective and ongoing improvements ensure a reduction in waste, as well as immediate change whenever the smallest inefficiency is observed.
Benchmarking
Benchmarking is the technique that employs a set standard of measurement. It involves making comparisons with other businesses to gain an independent appraisal of the given situation. Benchmarking may involve comparing important processes or departments within a business (internal benchmarking), comparing similar work areas or functions with industry leaders (functional benchmarking), or comparing similar products and services with that of competitors (competitive benchmarking).
Poka-yoke (Mistake Proofing)
This technique's name comes from the Japanese phrase meaning "to avoid errors," and entails preventing the chance of mistakes from occurring. In the poka-yoke technique, employees spot and remove inefficiencies and human errors during the manufacturing process.
Value Stream Mapping
The value stream mapping technique charts the current flow of materials and information to design a future project. The objective is to remove waste and inefficiencies in the value stream and create leaner operations. It identifies seven different types of waste and three types of waste removal operations.

2. What Does Six Sigma Mean?
Six Sigma is a quality improvement methodology for businesses that counts the number of flaws in a process and aims to systematically fix them. Businesses utilize it to get rid of flaws and enhance any of their procedures in an effort to increase earnings.
3. What Is the Difference Between Six Sigma and Lean Six Sigma?
Lean and Six Sigma vary primarily in that Lean frequently affects all aspects of an organization rather than being solely focused on production. These two strategies are combined by Lean Six Sigma to produce a potent toolkit for dealing with waste reduction.
4. What Are the Steps of Six Sigma?
Six Sigma's five steps adhere to a methodology known to business insiders as DMAIC. The words "define, measure, analyze, enhance, and control" are all spelled out in this acronym.
5. What is Lean Six Sigma?
Lean Six Sigma is a method for improving performance by systematically removing waste and reducing variation that relies on a collaborative team effort. Increased performance and decreased process variation contribute to defect reduction and improvements in profits, employee morale, and product or service quality.
6. What is continuous improvement?
Continuous improvement (also known as "rapid improvement") is a Lean improvement technique that aids in workflow optimization. The Lean method of working allows for efficient workflows that save time and money, allowing you to cut down on wasted time and effort.
7. What is Lean Six Sigma Yellow Belt?
A Certified Lean Six Sigma Yellow Belt from the Council for Six Sigma Certification (CSSC) is someone who has a basic understanding of Six Sigma but does not lead projects on their own. They are frequently in charge of creating process maps to support Six Sigma projects.
8. What is Lean Six Sigma Green Belt?

How to Solve Your Problems With Lean Six Sigma (Free DMAIC Checklist)
Elisabeth Swan is the co-author of “The Problem-Solver’s Toolkit” and co-host of “The Just-in-Time Cafe Podcast.” She’s been a process improvement consultant, speaker, and innovator for over 30 years. She’s the Chief Learning Experience Officer for GoLeanSixSigma.com, a former cast member of ImprovBoston, and – if asked – may still be able to ride a unicycle.
Surgeon Atul Gawande made headlines when he told the world that a simple checklist could drastically reduce unnecessary deaths in The Checklist Manifesto .
Yet, checklists conjure images of forklift drivers on loading docks with clipboards counting boxes. How could they transform healthcare?
“ He has… produced a 90-second checklist which reduced deaths and complications by more than one-third in eight hospitals around the world – at virtually no cost and for almost any operation. ” – James Clarke, reviewing The Checklist Manifesto, Ulster Med J. 2011 Jan; 80(1): 54.
Aviation was transformed decades earlier when management and engineers at Boeing Corporation created the pre-flight checklist after the 1935 crash of the prototype Boeing B-17 at Wright Field in Dayton, Ohio. Checklists have become so essential to the airline industry that most crashes can be traced to the misuse or failure to complete a checklist.
A New York Times reviewer noted, “no matter how expert you may be, well-designed checklists can improve outcomes”. Since the purpose of process improvement is improving outcomes, Lean Six Sigma and checklists are natural companions.
To prove that, this Process Street blog post will show the relationship between checklists and lean six sigma, and provide you with a free DMAIC Improvement Project Tollgate Checklist that you can use right now.

Lean Six Sigma and the role of problem-solving
Lean six sigma & the checklist, introduction phase, define phase, measure phase, analyze phase, improve phase, control phase, checklists and lean six sigma, use process street to reduce error.
Or, if you just want the checklist, check it out below!
Let’s get started.
For those unfamiliar with Lean Six Sigma and process improvement, it is a structured approach for organizations to scrutinize how things are done, poke at data and processes to uncover waste and then cut out things like extra forms, out-dated approvals and other time-wasting steps.
It’s a customer-focused, 5-step problem-solving model that engages entire workforces to constantly seek a better way of doing things.
Proof of Lean Six Sigma’s influence is evident in today’s hiring practices. A poll by GoLeanSixSigma highlights that hiring managers prefer a person who is “ Green Belt Certified ” – having substantial Lean Six Sigma skills – by an almost 80% margin. In an interview with the former head of Twitter, problem-solving emerged as the top skill sought by today’s most influential hiring managers.
In other words, problem-solving (especially via Lean Six Sigma) is an absolutely vital skill.
If problem-solving is a must-have skill and checklists are key to good outcomes, then combining the two makes sense.
DMAIC – Define, Measure, Analyze, Improve & Control – is the 5-Step model for Lean Six Sigma and there’s a set of required tollgates at the end of each phase. These tollgates outline what has to be done in order to move the problem-solving process forward.
Using the tollgates as an outline, we created a dynamic Process Street template that you can use for free and run checklists from to track your progress!
Before you can start solving problems, you need a problem to solve.
Picking a process issue – and finding someone in leadership to support you – are two required tasks in this first tollgate. Scoping the project is important (bigger than a “just-do-it” and smaller than “solving world hunger”) but even more critical is finding a Sponsor.
Finding a Sponsor
In a poll asking Lean Six Sigma practitioners what they considered the biggest obstacle to process improvement success, “Getting Leadership Support” accounted for almost a third.
When we coach team leads who tell us they can’t find someone to back their project, we let them know, “No Sponsor, no project”. If nobody in charge has any skin in the game, there’s no point in attempting the process fix. Find a different project that leadership supports.
One thing that helps when searching for leadership backing is being able to explain what Lean Six Sigma is and why it makes a difference. Since the checklist template is dynamic we inserted a video in the Define Phase within the checklist item, “Enlist a Project Champion/Sponsor who will support you and the project”. The team lead can share the video with managers or directors who they consider Sponsor candidates.
There’s also a Project Selection Guide Template embedded in the checklist so users can take a project idea and put it through a few screening questions. Is it a repeating problem? Is there a way to measure it? The checklist serves as a reminder, a source of templates, supporting videos and other just-in-time guidance.
The next set of tollgate tasks cover the Define Phase of DMAIC. This is where problem-solvers clarify the problem, the process impacted and customers of the process.
There is a journey of discovery during this phase as everyone agrees on the issue to solve. One of the big challenges is the tendency of ambitious team leads—or equally ambitious Sponsors—to try to “shoot the moon.”
Shooting the moon
They might want to reduce cycle time, reduce defects , improve margins, and increase customer satisfaction all by next Tuesday. But a project that focuses on everything accomplishes nothing. It’s okay to measure the cost reduction that results from reducing defects. But pick one of those to be the goal. Success is more possible if you focus on one goal at a time .
It takes practice and discipline to develop a manageable goal statement. Another moon shot is aiming for perfection out of the starting gate. When we see a goal statement that claims the team will, “reduce defects from 25% to 0%” then we know there is a sizable risk of failure and disappointment.
That’s why the Define Phase of the checklist includes a Goal Builder Template along with a blog providing tips on how to create well-crafted goal statements.
The primary focus of the Measure Phase is to baseline the process. If you’re trying to reduce defects, you need to know how you’re doing at that now. What’s your track record? You need to know the baseline of the process in order to measure whether or not you made a difference with your improvement when you get to the Improve Phase.
You need to know the gap, so you can close the gap.
The data’s in the system, somewhere…
One of the issues we run into in this phase is problem solvers assuming that data is sitting in a system somewhere waiting to be accessed. If they simply run a report, they’ll have the baseline. Check that off the list. But that rarely goes according to plan.
Maybe there’s system data, but was it entered with care? Is it reliable? We’ve seen teams struggle to use data that didn’t make sense. They could access cycle time data, but it didn’t take into account that the workday ended at 5:00. I had another team looking at why healthcare invoices had to be manually adjusted. They looked up the defect codes and the biggest category was “Other”. System data existed, but it was useless.
Most of the time, it helps to collect some data manually. In order to think through your approach, you need a Data Collection Plan. That involves listing the data you want and considering things like stratification factors—the “who, what, when, where” of data. If you’re looking at defects, should you collect data on defects by product? Defects by the fields on a form? Defects by customer type?
Within the task: “Develop a Data Collection Plan with Operational Definitions and create Check Sheets as Needed”, we’ve embedded a template (The Data Collection Plan) and a video to guide the process.
You’ll learn a lot by collecting the data firsthand, so if the perfect data set is not magically sitting in the system, it helps to have a plan.
Analyze is the crux of the DMAIC method. This is where learners drill down and discover the root cause of the process problem they’ve been chasing. Once you do that, you can solve the problem for good.
But if you have not determined the root cause then you might be solving a “symptom,” putting a bandaid on the problem or implementing a change based on a hunch. All of this means there’s a high likelihood the problem will remain and the efforts will have been in vain.
Finding the smoking gun
If you’ve always been told, “don’t bring me a problem, bring me a solution,” that’s an encouragement to jump right past this step into the fun of solutions. I’ve seen teams go with their assumptions regardless of what the data says or the process analysis reveals. I’ve seen Sponsors who tell teams what solutions they want to be implemented right from the get-go.
How do you stick with analysis long enough to find the smoking gun? The trick is to keep collecting the clues in the Cause & Effect Diagram , aka The “Fishbone Diagram”. It’s an aptly named tool, popularized by Dr. Ishikawa , which resembles a fish skeleton. Its construction allows teams to develop root cause theories around a problem as they build their knowledge of the process.
Each time they collect data, interview process participants on a Gemba Walk or map the process steps, they uncover potential reasons for defects. Making the most of the Fishbone Diagram is key but, during a poll, users reported where they fell short.
Solutions masquerading as problems
Over a third of respondents reported the issues of “listing solutions” on the Fishbone instead of causes. What we hear are phrases like, “the root cause is a lack of training”.
The problem with “lack of” anything is that it’s a sneaky way of putting a solution on the Fishbone.
The question is, “what is the training addressing?” Is it lack of user knowledge? If that’s the problem, could it be solved with helpful visuals, a simpler process? There are a lot of ways to address user knowledge before jumping to more employee training.
This is when you want to behave like the persistent detective – think Columbo, the classic 70’s TV icon. Every question helps you accumulate clues. People working through the process may have the answer without knowing it. The trick is to keep looking upstream until you find potential culprits. Dig past the symptoms.
To help with this phase, the checklist includes both a Fishbone Diagram Template as well as a video on how to get the most out of the Fishbone.
The Improve Phase is a long-anticipated step in the journey. It’s the step teams generally want to jump to from the start. Testing countermeasures, piloting solutions, watching the problem disappear, that’s the fun of process improvement. If you’ve done a proper job of Define, Measure, and Analyze, this phase falls nicely into place.
The ripple effect
The catch? Unintended consequences.
If you toss a stone into a lake you can see the ripples flow out from the center. The same principle holds true for process change. If you remove a step, change a form, skip an approval , will things fall apart? For that, we look to the Failure Modes & Effects Analysis or FMEA for short.
It’s a methodical way of assessing the potential for things to go wrong. It Involves deciding the potential severity and frequency of future problems and then mistake-proofing the process to prevent them. The technique originated at NASA since they couldn’t risk trial and error when sending men to the moon. By thinking through the risks of change they developed the kind of contingency plans you saw on display in movies like Apollo 13.
That’s why there’s an FMEA Template and a video on how to use it tucked into the main checklist from this post.
It’s okay to make changes. It’s simply key to think through the impact of those changes on other parts of the business.
Process Improvement can happen quickly and have a dramatic impact, but it’s critical to “stick the landing.” The Control Phase exists to see the improvement through to stability.
If teams move on and everyone takes their eyes off the ball, things may start to slip. What they need is the ability to continuously see the performance of the new process.
Sticking the landing
Have you ever tried to watch a game without a scoreboard? How would you know who was winning? Or how much time was left?
It’s the same with process work.
How does your team know how they’re doing? How do you stay aware of how the new process is performing?
By making the data visible.
Keeping an eye on Process Performance can be done with a single metric — you need to focus on one thing. If the goal was to reduce defects, then the single metric would be tracking the daily percentage of defects. A great way to measure success is with a Control Chart.
Control Charts are time charts. You might know them as Line Charts or Run Charts. They include a measure of variation so they are often referred to as “Run Charts that went to college”. They can be created in Excel , but they can also be drawn by hand.
Teams often set up whiteboards in the shared workspace to track things like defects. People can rotate responsibility for updating the chart. If people can see the measure and are responsible for it—they pay attention to it. What gets measured gets managed.
The Control Chart Template is embedded in the checklist for the Control Phase.
Process Improvement is a mainstay of Operational Excellence and checklists are simple but effective ways to make sure you get the outcomes you want. The following quote comes from the interim CEO/President of the Association for Manufacturing Excellence ( AME ).
“ I am a big fan of checklists for ensuring quality at the source. They serve an important purpose in reminding us of all that’s needed in a particular process or project. Without checklists, we risk missing or overlooking something by mistake. Checklists work best when ticking off items as they are completed, not en masse once the entire project is done. The key point is to use and follow them, not “pencil-whip” them from memory after the fact. While not foolproof, checklists can help us cover the details and result in more thorough, successful improvement efforts. ” – Jerry Wright , President, AME

Limitations of Six Sigma Steps and What to Do About Them
Reading time: about 6 min
Posted by: Lucid Content Team
What is the goal of any project management methodology? To eliminate waste and streamline processes.
With that in mind, it’s easy to see why Six Sigma became so popular and why so many industries have scrambled to find ways to apply it. Who doesn’t like to accomplish tasks faster while saving money?
However, if it's incorrectly applied, Six Sigma can do more harm than good. In the quest to refine processes and eliminate waste, Six Sigma may limit flexibility for unique circumstances, and leave less room for innovative new tools or methods.
Let’s review what makes up the process of Six Sigma, how to follow the Six Sigma steps, where the limitations of the methodology lie, and what methods or tools companies may want to use instead.
To get started, here's an overview of the Six Sigma steps that you can easily customize and share with your team.
What is Six Sigma?
The Six Sigma methodology was developed in the mid-1980s by engineers at Motorola as a way to improve manufacturing processes. At its core, Six Sigma involves collecting and leveraging data to eliminate defects and waste in manufacturing, with the end goal of improving overall efficiency and quality.
The term “sigma” is a measurement of how far from perfect a system or producer can get—by Six Sigma standards, companies should reduce manufacturing defects to less than 3.4 per 1 million units.
Businesses use the Six Sigma methodology to improve processes by identifying the errors that lead to defects and implementing new management systems once errors have been addressed. The methodology is most effective with repetitive, assembly line-style operations where individual steps can be isolated, examined, and improved upon.
How is Six Sigma used?
Originally developed for manufacturing, Six Sigma can now be found across many industries. However, just because companies in different sectors have applied this methodology doesn’t necessarily mean that these companies have used it correctly or effectively. Outside of a manufacturing operation, Six Sigma often fails to yield the kind of results needed to justify such a time-consuming and expensive management change.
To function effectively, Six Sigma requires buy-in from everyone involved. It requires a sizable upfront cost to implement and train employees on the methodology of Six Sigma and its execution.
Employees of all levels must be trained in the various positions of the methodology as well. Individuals who have completed a Six Sigma certification class earn belts to designate their level—Green Belts are for beginners, Black Belts are for project leaders, and Master Black Belts are for those in charge of implementing Six Sigma throughout the business.
What are 5 steps for Six Sigma?
The Six Sigma steps for process improvement, also referred to as DMAIC, are fairly direct and straightforward.
- Define the problem. Craft a problem statement, goal statement, project charter, customer requirement, and process map.
- Measure the current process. Collect data on current performance and issues. Verify that the data is reliable, and update the project charter as needed.
- Analyze the cause of issues. Examine the process and data that was collected, display the data, investigate and confirm what’s causing the issues, and continue updating the project charter as needed.
- Improve the process. Decide on solutions to fix issues and create process maps for those new solutions. Take steps to implement the new fixes and continue to measure improvement.
- Control. Refine the new process, continue monitoring, and use findings elsewhere in the business, if possible.
What are the limitations of Six Sigma?
One of the challenges of the fact-driven process of identifying a problem and working toward a solution is that it tends to leave out a key component: humans—and more importantly, how humans impact and work through different obstacles. Sometimes it is often beneficial to give employees a chance to tackle issues head-on before investing in a complete operational overhaul.
The one-size-fits-all approach to Six Sigma can also be somewhat limiting at times, especially within organizations or disciplines that rely on creativity. Employees who crave the freedom to toss caution (and sometimes process) to the wind in an effort to innovate may find the Six Sigma process stifling.
Six Sigma also does not technically allow for the introduction of new tools or methods, even when they could be beneficial. Since Six Sigma generally requires total dedication across all teams, it’s difficult to use or experiment with other process methodologies for other areas of the organization.
What can you use instead of Six Sigma?
Dozens of project management methodologies exist with varying degrees of structure, rules, and processes. Here are just a few of the most common:
Waterfall methodology : Made up of discrete, sequential tasks, the waterfall methodology for project management ensures each step is completed in the correct order to achieve the final product.
Scrum methodology : As an agile methodology, scrum uses an incremental approach that allows for small teams to work simultaneously on deliverables, testing and adjusting course throughout to complete projects quickly.
Kanban : Relying on notecards to visually represent and prioritize project tasks, Kanban boards track the project through stages to keep everyone on the same page.
Agile methodology : Driven by customer needs, Agile produces deliverables using iterative cycles to continuously refine until a final product is created.
To decide which style is ideal for your project or organization, try working backward. Start with what you want your end product to look like.
Borrow from Six Sigma principles and conduct a fact-finding mission, evaluating where your team is already successful, what’s working well, and what type of environment drives those ideal results. Does your organization do best in large teams or small teams? Do team members like two-week sprint schedules or more free-form processes? Use the information you’ve gathered as a guide to investigate which project management methodology works for your specific goals, constraints, and timelines.
Keep track of the pros and cons of each type of project management style, and decide with key stakeholders which process makes the most sense for your unique situation.Determine the best methodology to meet your needs with the ultimate guide to project management methodologies and make sure your project goes off without a hitch.
You don’t need to stick rigidly to the rules of just one project management process. Rather, be open to taking the best parts of different methods and using them to your advantage.
Beyond Six Sigma
Six Sigma should be recognized and celebrated for what it is: a data-driven approach to streamlining production and manufacturing. For industries and businesses outside of manufacturing, though, teams should explore more flexible project management or process improvement methodologies. For all its successes, Six Sigma can’t replace human ingenuity and hard work. Look instead to the brain power in your organization, and find a methodology that works with your team’s creativity and can be customized where needed.
