How Lean and Six Sigma Work Together
While both Lean and Six Sigma aim to reduce waste, they are distinct methodologies. Six Sigma focuses on reducing defects by limiting variation within a process, while Lean removes unnecessary steps for a more efficient process. Combining these two methodologies can improve business performance by emphasizing both quality improvement and profitability. Learn more about Lean Six Sigma by reading Everything You Need to Know About Lean Six Sigma.
The acronym “DMAIC” represents a key aspect of Lean Six Sigma. DMAIC stands for the five phases of an improvement cycle: Define, Measure, Analyze, Improve, Control. You can use these steps as a roadmap for resolving issues with a Six Sigma approach:
- Define the project goals or problem to be addressed, internal and external customer requirements, and project boundaries.
- Measure the current performance of the process and describe the process in quantifiable terms.
- Analyze the process and identify the root causes of defects and sources of variation.
- Improve performance by resolving the root causes of issues and eliminating defects.
- Control future process performance by maintaining improvements.
Another version of this process is DMADV (Define, Measure, Analyze, Design, and Verify). The DMADV framework is typically applied to new products or services, rather than improving an existing process, or when an existing process has been improved but is not meeting a Six Sigma level. The process is similar to DMAIC but focuses on product or process design and how to implement that design effectively.
Six Sigma Tools
Six Sigma is a quality measurement that represents 3.4 Defects Per Million Opportunities. That’s a lofty goal for many business processes, but you can use Six Sigma methods to improve quality and performance in varying degrees based on the needs and objectives of a business or project. Six Sigma tools range from statistical charts, illustrative diagrams, and data collection methods to project management and process analyzation worksheets. These tools may not be exclusive to Six Sigma, but they can be applied in specific ways to focus on process improvement. The tools required depend on the project requirements and team roles. Depending on one’s training and experience, a Six Sigma professional may be involved in improvement initiatives at the White, Yellow, Green, or Black Belt level. White Belts generally have supporting roles, while Yellow Belts act as team members, Green Belts collect and analyze data, and Black Belts serve as project leaders.
In the following sections, you’ll find a number of free, downloadable templates that you can use as Six Sigma tools.
Project Charter Template
This Six Sigma Excel template is designed to help you create a project charter that will serve as an agreement between management and your team. A project charter provides an overview of a project including team roles and responsibilities, financial information, goals, and constraints. Creating a detailed project charter will help define your project and its expected outcome, and provide a high-level roadmap to follow.

SWOT Analysis Template
Use this SWOT analysis template for strategic planning and to create dynamic PowerPoint presentations. List the strengths, weaknesses, opportunities, and threats related to an idea, process, or organization, and use this information for strategic analysis. Easily add this PowerPoint slide to any presentation for visual communication with project team members or other stakeholders.

Fishbone Diagram Template
A fishbone diagram, also known as a cause and effect diagram or Ishikawa diagram, helps teams brainstorm the causes of a certain event. Use this Six Sigma tool along with the 5 Whys template to determine root causes. One of the benefits of using a fishbone diagram is the visual layout, which makes it easy to compile and view information, and see the relationships between different elements.
A3 is an approach to problem solving that grew out of Lean Manufacturing at Toyota. The A3 report condenses project information onto a single page in an easy-to-read, graphical format. This A3 template provides sections for describing background information, current conditions, root cause analysis, target conditions, implementation plan, and follow-up.
5 Whys Template
A 5 Whys worksheet can help you undertake a root cause analysis to determine the sources of defects or performance issues. After defining the problem, you ask five questions to drill down into why the problem is happening, and track the issue back to its root cause. The final step is to determine what action you should take to eliminate that root cause.

Project Prioritization Analysis
This template can help you prioritize and select projects based on various factors, such as likeliness to succeed, cost, and how critical a project is to business processes. Once you collect your data, you can also use a Pareto chart to get a visual representation of the results. This Six Sigma project template is a simple tool that can have a big impact on decision making.
SIPOC Diagram Template
SIPOC stands for Suppliers, Inputs, Process, Outputs, and Customers. A SIPOC diagram provides a high-level, visual overview of a business process, which is helpful for identifying and summarizing all of the elements in a process improvement project from start to finish. This Excel template provides five columns to create a simple, easy-to-read diagram.
Communication Plan Template
A communication plan outlines how and when you will communicate a project to stakeholders. Effective messaging is important for securing buy-in as well as ensuring continued support for the duration of a project. Consistent reporting on project progress and milestones can help keep stakeholders informed and engaged.

Voice of Customer (VOC) Six Sigma Template
Use this VOC template to gather information about customer expectations and needs. Gaining insight into customer requirements can inform your improvement process and help ensure a successful end product. This template is designed to help you document the voice of the customer and translate those messages into measurable requirements.
Data Collection Plan Template
During the “measure” phase of DMAIC, you can use a data collection plan template as a framework for describing what type of data to collect, how to gather it, when, and by whom. This spreadsheet template provides columns for entering data sources and locations, operational definitions, what statistical tools to use, and more. You can also edit the template to include any additional information that is relevant for your project.
A Failure Modes and Effects Analysis (FMEA) seeks to prevent possible failures in a design or process. This FMEA template is designed to help you follow a systematic approach to identifying, understanding, and preventing failures. The template includes a section for recording what actions were taken to address each issue, as well as the completion date.
Control Plan Template
During the “control” phase, an effective plan serves as a guide for monitoring process and sustaining improvements. In this simple spreadsheet template, you can document process control activities to help ensure that quality standards continue to be met. Customize the template as needed to create a control plan for your specific project.
Cause and Effect Matrix
A cause and effect matrix allows you to evaluate and quantify the relationships between process inputs and outputs. Use the matrix to prioritize process inputs based on the level of impact each one has on outputs. Once you collect your data in the matrix, you can also represent the results in a Pareto chart.
Pareto Chart Template
Use this template to perform a Pareto analysis of your data to determine the frequency of problems or defects occurring in a process. The template provides a typical Pareto diagram, with a bar chart representing whatever issues you want to analyze, and a line graph showing the cumulative percentage of occurrences.
Tree Diagram Template
A tree diagram breaks down a central concept, issue, or activity into increasingly smaller components. In Six Sigma, tree diagrams are used for determining root causes, brainstorming ideas related to a central topic, understanding a process from top to bottom, and approaching issues systematically. This is a useful tool for teams at many levels.
8D Report Template
This template guides you through the 8D (eight disciplines) approach to problem solving and process improvement. The 8D report includes separate sections for each step, from describing the problem and root causes to identifying corrective actions and ways to prevent reoccurrence.
