Six Sigma is a data-driven methodology that aims to improve the quality and performance of business processes by reducing variation and defects. It was developed by Motorola in the 1980s and popularized by General Electric in the 1990s. Since then, it has been adopted by many organizations across different sectors and industries.
An Introduction To Six Sigma And Process Improvement James R. Evans
Six Sigma is important because it helps organizations achieve excellence in customer satisfaction, operational efficiency, profitability, and innovation. By applying Six Sigma, organizations can:
Identify and eliminate the root causes of problems that affect quality
Measure and monitor the performance of processes using statistical tools
Analyze and optimize the processes using data-driven decisions
Implement and sustain the improvements using standardization and control
Innovate and create new value for customers using design thinking
However, Six Sigma is not without its challenges. Some of the common difficulties that organizations face when implementing Six Sigma are:
Lack of leadership commitment and support
Lack of organizational culture and readiness for change
Lack of resources and skills for training and execution
Lack of alignment and integration with other business strategies and initiatives
Lack of customer focus and involvement
To overcome these challenges, organizations need to understand the key concepts and principles that underpin Six Sigma.
What are the main methodologies and tools of Six Sigma?
Six Sigma is based on two main methodologies that guide the improvement projects: DMAIC and DMADV. Each methodology consists of five phases that follow a logical sequence.
The DMAIC (Define, Measure, Analyze, Improve, Control) approach
DMAIC is used for improving existing processes that are not meeting customer expectations or performance goals. The five phases of DMAIC are:
Define: Define the problem, the goal, the scope, and the team of the project.
Measure: Measure the current performance of the process and collect relevant data.
Analyze: Analyze the data and identify the root causes of the problem.
Improve: Improve the process by generating and implementing solutions.
Control: Control the process by monitoring and verifying the results and ensuring sustainability.
The DMADV (Define, Measure, Analyze, Design, Verify) approach
DMADV is used for designing new processes or products that meet customer needs and specifications. The five phases of DMADV are:
Define: Define the customer requirements, the project goals, and the project plan.
Measure: Measure and quantify the customer needs and expectations.
Analyze: Analyze the data and identify the gaps and opportunities for improvement.
Design: Design the new process or product that meets or exceeds the customer requirements.
Verify: Verify the design by testing and validating its performance and functionality.
The Lean Six Sigma approach
Lean Six Sigma is a combination of Lean and Six Sigma principles and practices. Lean focuses on eliminating waste and non-value-added activities from processes, while Six Sigma focuses on reducing variation and defects from processes. By integrating Lean and Six Sigma, organizations can achieve faster and better results with less resources and costs. The Lean Six Sigma approach follows the DMAIC methodology with some modifications and additions.
The common tools and techniques of Six Sigma
Six Sigma relies on a variety of tools and techniques to support each phase of the improvement projects. Some of the common tools and techniques are:
Voice of the Customer (VOC): A tool to capture and analyze the needs, expectations, preferences, and feedback of customers.
SIPOC (Suppliers, Inputs, Process, Outputs, Customers): A tool to map and understand the high-level view of a process.

Pareto Chart: A tool to prioritize and focus on the most significant causes or issues based on their frequency or impact.
Control Chart: A tool to monitor and control the variation and stability of a process over time.
Histogram: A tool to display and analyze the distribution and shape of a data set.
Scatter Plot: A tool to explore and visualize the relationship between two variables.
Brainstorming: A technique to generate a large number of ideas or solutions in a group setting.
Affinity Diagram: A tool to organize and group similar or related ideas or solutions into categories.
Multivoting: A technique to prioritize and select the most important or relevant ideas or solutions from a list.
Pilot Testing: A technique to test and evaluate a solution or a change on a small scale before implementing it on a large scale.
Standard Operating Procedure (SOP): A document that describes the steps, roles, responsibilities, rules, and guidelines for performing a process or a task consistently and correctly.
Checklist: A tool to ensure that all the required actions or items are completed or verified in a process or a task.
Audit: A technique to assess and verify the compliance and effectiveness of a process or a system against predefined standards or criteria.
How to implement and manage Six Sigma projects?
Six Sigma projects require careful planning, execution, management, and evaluation. To ensure success, organizations need to define clear roles and responsibilities for Six Sigma professionals, follow a systematic project selection and scoping process, apply effective project management and communication skills, and conduct regular project evaluation and improvement activities.
The roles and responsibilities of Six Sigma professionals
Six Sigma professionals are classified into different levels based on their skills, knowledge, experience, and responsibilities. The main levels are:
Champion: A senior leader or manager who sponsors, supports, and oversees the Six Sigma projects and initiatives in the organization. They are responsible for setting the strategic direction, allocating the resources, removing the barriers, and ensuring the alignment and integration of Six Sigma with other business goals and priorities.
Master Black Belt: A highly experienced and certified Six Sigma expert who provides training, coaching, mentoring, and guidance to other Six Sigma professionals. They are responsible for developing and maintaining the Six Sigma curriculum, standards, and methodologies, as well as leading complex and cross-functional projects and initiatives.
Black Belt: A full-time and certified Six Sigma professional who leads and manages the Six Sigma projects and teams. They are responsible for applying the Six Sigma methodologies and tools, conducting data analysis and statistical tests, generating and implementing solutions, and delivering results and benefits.
Green Belt: A part-time and certified Six Sigma professional who participates in or supports the Six Sigma projects and teams. They are responsible for assisting the Black Belts in data collection and analysis, problem solving, improvement implementation, and process control.
Yellow Belt: A basic-level and trained Six Sigma professional who has an awareness and understanding of the Six Sigma concepts and principles. They are responsible for applying some of the basic Six Sigma tools and techniques in their daily work processes and activities.
The project selection and scoping process
Six Sigma projects should be selected and scoped based on their alignment with the organizational vision, mission, values, goals, and customer needs. The project selection and scoping process involves four steps:
Identify potential opportunities for improvement: This step involves collecting and analyzing data from various sources, such as customer feedback, employee suggestions, process performance metrics, benchmarking studies, etc., to identify the gaps or problems that need to be addressed.
Prioritize and select the most critical opportunities for improvement: This step involves evaluating and ranking the potential opportunities based on their impact, feasibility, urgency, risk, cost, etc., to select the most critical ones that will deliver the most value to the organization and customers.
Define the scope and objectives of the selected project: This step involves defining the scope of the project by specifying its boundaries, deliverables, assumptions, constraints, etc., as well as defining the objectives of the project by stating its expected outcomes, benefits, measures, targets, etc.
Develop a project charter: This step involves documenting and communicating the scope and objectives of the project in a concise and clear format that summarizes the key information about the project. The project charter serves as a contract between the project team and the project sponsor that outlines their roles, responsibilities, expectations, authority, etc.
The project management and communication process
and collaboration. The project management and communication process involves four steps:
Plan the project activities and resources: This step involves developing a detailed plan that outlines the tasks, milestones, deliverables, resources, roles, responsibilities, timelines, budgets, etc., for each phase of the project. The plan should be realistic, flexible, and adaptable to changing situations and needs.
Execute the project activities and deliverables: This step involves implementing the plan and performing the tasks and deliverables according to the agreed standards and specifications. The project team should work together as a cohesive unit and leverage their skills, knowledge, and experience to achieve the project objectives.
Monitor and control the project performance and progress: This step involves tracking and measuring the performance and progress of the project against the plan and objectives using various tools and techniques, such as dashboards, reports, charts, graphs, etc. The project team should identify and resolve any issues or risks that may affect the quality or timeliness of the project outcomes.
Communicate the project status and results: This step involves communicating the status and results of the project to various stakeholders, such as the project sponsor, champion, master black belt, black belt, green belt, yellow belt, customers, employees, etc., using various methods and channels, such as meetings, presentations, emails, newsletters, etc. The project team should provide clear, concise, accurate, and timely information that informs, educates, engages, and influences the stakeholders.
The project evaluation and improvement process
Six Sigma projects should be evaluated and improved using a continuous learning and feedback loop that ensures sustainability and scalability. The project evaluation and improvement process involves four steps:
Evaluate the project outcomes and benefits: This step involves assessing and quantifying the outcomes and benefits of the project using various criteria and indicators, such as customer satisfaction, process performance, financial impact, operational efficiency, etc. The project team should compare the actual results with the expected targets and identify any gaps or deviations.
, case studies, etc. The project team should capture and share the key insights and recommendations that can help improve future projects and initiatives.
Implement the improvement actions: This step involves implementing the improvement actions that are derived from the evaluation and feedback of the project. The project team should prioritize and execute the actions that can enhance the quality and performance of the process or product, as well as the satisfaction and loyalty of the customers.
Review and update the process documentation: This step involves reviewing and updating the process documentation that reflects the changes and improvements made by the project. The project team should ensure that the documentation is accurate, complete, consistent, and accessible to all relevant stakeholders.
