What Is Lean Six Sigma?
Lean Six Sigma is a smart blend of two methodologies: lean and Six Sigma. Toyota developed the lean technique in the 1940s to streamline its manufacturing process and boost productivity. The lean methodology is centered on streamlining operations and optimizing workflows to remove non-value-adding activities from the manufacturing process. It involves reducing and eliminating eight types of waste, known as DOWNTIME: defects (overproduction), waiting, non-utilized talents, transportation, inventories, motion, and extra processing.
On the other hand, a Motorola Corporation engineer invented Six Sigma in the 1980s, drawing inspiration from the Japanese Kaizen concept. This method eliminates errors and waste in production processes.
This method served as the basis for Lean Six Sigma, which blends Six Sigma’s data-driven problem-solving methodologies with Lean’s core values. Combined, these techniques offer a thorough framework that helps businesses improve their workflows, eliminate waste, and offer outstanding value to customers.
Establishing clear objectives and knowing what your consumers value can help you lay a strong basis for implementing lean Six Sigma in your own company. Next, identify and analyze your current processes to uncover areas of waste and inefficiency. With the right training and lean Six Sigma tools, you can make data-driven improvements that will significantly impact your bottom line. It follows a structured approach known as DMAIC: define, measure, analyze, improve, and control.
Benefits of Using Lean Six Sigma in Your Business
Putting Lean Six Sigma into practice in your organization has several advantages, summarized in six key benefits below.
Simplify Your Business Processes
A lean Six Sigma methodology will help your organization reduce waste and identify non-value-added tasks. This can simplify processes and eliminate unnecessary steps that don’t bring value. This leads to increased efficiency, reduced cycle times, and improved productivity. It’s like decluttering your workspace so that only the essentials remain, making processes easier to manage and execute.
Make Fewer Errors and Mistakes
When it comes to the lean Six Sigma process, the first step is to establish the desired level of quality that meets customer expectations. Prioritize continuous improvement efforts to address the problems that impact business success most. This results in changes that fix real problems and bring them to a level acceptable to real customers, addressing the errors and mistakes that mean the most.
Ensures Predictable Performance From Employees
This methodology sets clear standards and procedures, which means employees know exactly what’s expected of them. It creates simple processes with less variance that are easier to oversee and manage, resulting in more predictability. Predictable cycle times, quality output, and costs contribute to improved customer service, fewer complaints, and more revenues.
Satisfy Your Customers
Lean Six Sigma principles use tools and techniques to create a customer-focused operation with customer experience on the front burner. By enhancing processes and effectively overseeing quality, organizations can achieve superior products and services. As a result, you will be able to provide exceptional customer satisfaction and encourage repeat sales.
Drives More Sales and Revenue
The lean Six Sigma methodology also helps businesses increase the speed and effectiveness of their lead generation efforts by eliminating waste and reducing variability in lead generation processes. This means that more leads are generated in a shorter period and with fewer resources, which will lead to increased revenue and profitability. It helps create a ripple effect of satisfaction that spreads, increasing sales and boosting revenue.
Reduces Operational Costs
By eliminating non-value-adding activities, automating repetitive tasks, and enhancing process and resource efficiency, businesses can significantly reduce operational costs and improve service levels. When you streamline your operations, you save time and resources and cut down on expenses. Implementing lean Six Sigma principles within your organization is a great approach to operational excellence through efficiency.
7 Key Principles of Lean Six Sigma
In the fast-paced and globalized world of business today, competition is strong. As such, organizations need to keep an edge in the marketplace, which drives businesses to explore new lean management techniques. The seven key lean Six Sigma principles are guidelines that help organizations improve their business processes.
Focus on the Customer
The principal objective of every business is to offer a product or service that its customers will pay for. Try to imagine yourself as your client and determine whether your offering lives up to their expectations. Identify your ideal customer profile and conduct surveys or hold focus groups to understand their needs, expectations, and pain points.
Align your processes to deliver value that directly addresses these needs. Highly successful businesses offer extra value according to their customers’ needs. Customer-centricity is another name for this concept.
Address a Real-World Problem
Don’t get mired down in hypothetical problems. Focus on identifying recurring issues that generate frustration for customers or hurdles for staff members. Brainstorm together to find the areas that require the greatest improvements—aim for the problems that deliver the most punch. Prioritize problems with the most impact. Collect data that suggests where your specific problem area sits and concentrate on refining that area.
Measure the Value Stream
Consider the entire process—from when a consumer places an order to when they receive the finished product—as a journey. Lean Six Sigma encourages mapping the journey and identifying each stop along the route. Track the time for each step, look for bottlenecks, and determine potential problem spots.
To build a value stream, all necessary persons, protocols, data, and inventory are provided in a flowchart. Value stream mapping can be done on a whiteboard using Post-its with extra information or flowchart software, as seen below.
Base Your Analysis on Data
Lean Six Sigma is a data-driven methodology that supports an organized, data-driven approach to process improvement inside an organization. It entails identifying, analyzing, and implementing changes rigorously and systematically by adhering to a specific methodology such as DMAIC.
Get Rid of Waste
The idea of waste removal initially appeared in the Toyota Production System. In the context of lean, waste is a “non-value-added activity,” and we are reducing that timeline by eliminating non-value-added waste. Lean Six Sigma aids in locating these inefficient processes. Eliminating inefficient operations may help companies make the most of their resources, increase profitability, and significantly improve operational efficiency.
Involve Stakeholders
Put together a team with members from each department affected by the problem. Their many viewpoints are invaluable. It underscores the relevance of stakeholders in the success of any project and the value of collecting and analyzing data to inform stakeholders about the workflow’s efficiency or inefficiency.
Ensure a Flexible and Responsive Ecosystem
Promoting a flexible and responsive ecosystem is the last principle. Change is inevitable. Once you have implemented improvements, do not just sit back and relax. Continually track and quantify the effectiveness of the new process. As required, be ready to modify and adapt. Remember, the goal is to continuously improve, so keep your finger on the pulse of your customer’s experience.

Lean Six Sigma Techniques and Tools
Here is how you can apply its techniques and tools to streamline your processes and foster a culture of continuous improvement.
Kanban
The Kanban technique of visual workflow management lets you monitor your activities and projects using cards and boards. Before implementing Kanban, start by defining the stages of your current workflow on a board. Next, utilize cards to represent tasks, moving them across the board as they complete each phase.
This visibility allows for tracking in real time and helps identify bottlenecks. At this point, SweetProcess helps you organize activities, track progress, visualize your workflow, and identify bottlenecks.
Kaizen (Continuous Improvement)
Kaizen is a steady, small-step improvement technique. It involves creating an atmosphere in which employees of all ranks actively participate in making suggestions for and carrying out process improvements within the organization.
SweetProcess can be utilized to document all improvement suggestions and allocate tasks to execute the best ideas. Next establish recurring tasks to review and modify processes.
Value Stream Mapping
A tool called value stream mapping helps you visualize and understand the information and material flow that occurs as a product moves through the value stream. Make a process map of your existing workflow, mark each phase, and then eliminate or streamline the stages that do not add value.
Use SweetProcess to create a flowchart that shows every stage of your product’s development. Using the task management feature, identify steps that don’t provide value and make plans to eliminate them.
The 5S System
The 5S system is a set of procedures for setting up and managing workspaces: sort, set in order, shine, standardize, and sustain. The first steps in implementing 5S are clearing unnecessary items, organizing tools, tidying the workspace, and maintaining these practices over time. Sort necessary items and schedule routine cleaning and standardization tasks using SweetProcess checklists.
Process Analysis
Process analysis involves examining your current procedures to identify areas for improvement. You dissect each process into its parts, evaluate each one’s efficacy and efficiency, and then modify the procedure to reduce waste and boost output. Use SweetProcess’s tracking tools to identify inefficiencies in each phase of your process, then adjust your standard operating procedures (SOPs) to reflect the more effective methods.
Root Cause Analysis
Root cause analysis is used to determine the fundamental causes of problems or events. Instead of treating only the symptoms of a problem, employ techniques like the five whys or the fishbone diagram to get to the root of the problem. As problems develop, note them down and utilize SweetProcess’s collaborative tools to discuss and identify the underlying causes. Then, assign corrective tasks to address the issues.
Voice of the Customer
Gathering customer feedback is referred to as the voice of the customer (VOC). Before successfully implementing VOC, engage with your customers through surveys, interviews, and feedback forms to understand their needs and expectations. Then, use this knowledge to inform improvements. Create surveys and questionnaires using SweetProcess to get feedback from customers.
The Five Phases of Lean Six Sigma
Lean Six Sigma is based on the problem-solving approach known as DMAIC. It is a five-step process that is explained below.
Define Phase
This phase is the foundation of your lean Six Sigma project. Identify the problem, use the voice of the customer (VOC) data to understand what customers want, and establish quantifiable, unambiguous objectives. This phase ensures everyone is aligned with the project’s goals and scope.
Measure Phase
This stage involves collecting data to gain insight into the process’s current status. Compile baseline data, establish a thorough process map, and validate your measurement system. Before making any adjustments, this stage aids in precisely assessing the process’s performance.
Analyze Phase
Part of the analysis process involves digging deeper into the data to identify the root causes of errors or inefficiencies. Tools like fishbone diagrams and Pareto charts help find problems and analyze trends.
Improve Phase
You create and put into practice solutions for addressing the core problems identified in the analysis phase during the improvement phase. Come up with a list of possible solutions, test them on a small scale, and implement process improvements that work. The goal of this stage is to make long-lasting and efficient improvements.
Control Phase
The control phase supports the long-term maintenance of the improvements made. Monitor process performance with control charts, update SOPs to reflect new practices, and conduct regular audits. This phase helps in maintaining progress and prevents redundancy.
Examples of Implementing Lean Six Sigma
Let’s see how Lean Six Sigma can be applied to real-world problems.
Reducing IT Downtime
Imagine a data-driven approach to IT downtime. Lean Six Sigma allows you to pinpoint the root cause: Is it peak usage times or specific software crashes? By analyzing data and implementing targeted solutions like optimizing server capacity or preventative maintenance, you can significantly reduce downtime and get everyone back online faster.
Minimizing Manufacturing Defects
Lean Six Sigma can be a game changer for manufacturing quality. By collecting data on defect rates and analyzing the root cause, be it equipment malfunctions or a need for training, you can implement corrective actions. This might involve recalibrating machinery, developing targeted training modules, or implementing stricter quality control procedures.
Optimizing Environmental Impact
Lean Six Sigma can be a champion for the environment. Imagine analyzing your waste stream to identify areas for improvement, such as excessive material usage or energy consumption. You can then implement solutions like exploring recycled materials, optimizing production runs to minimize waste, or finding ways to reuse packaging materials. These changes, combined with data analysis, can lead to significant environmental benefits.
Six Sigma vs. Lean Six Sigma: Differences and Similarities
Lean and Six Sigma are both process improvement methodologies. Each methodology has its goals and objectives and can be used separately or in conjunction.
The thin line between lean and Six Sigma has continued to be blurred. Both focus on improving business processes to enhance efficiency, quality, and productivity. They prioritize meeting customer needs through data-driven decision-making and emphasize continuous improvement.
Both methodologies aim to reduce waste, involve employees at all levels, and standardize processes to ensure consistency.
