What is Six Sigma?, Six Sigma is a systematic, data-driven approach and method for eliminating defects (aiming for six standard deviations between the mean and the nearest specification limit) in all processes, from manufacturing to trading, products to services. It was developed by Motorola and popularized by General Electric (GE) in the mid-1980s.

The main goal of Six Sigma is to reduce the variability of manufacturing and business processes, identify and eliminate the causes of defects, and improve the quality of process results. This approach uses a set of statistical and quality control tools, such as DMAIC (Define, Measure, Analyze, Improve, Control) or DMADV (Define, Measure, Analyze, Design, Verify), to systematically improve processes and eliminate the possibility of errors or defects.

Six Sigma professionals are typically trained in a variety of statistical methods and tools and work in organizations to carry out improvement projects, optimize processes, and achieve measurable results in terms of cost reduction, quality improvement, and customer satisfaction.

Six Sigma follows a structured approach called DMAIC, which stands for Define, Measure, Analyze, Improve, and Control. Each step plays an important role in the overall process improvement effort. A brief description of each step follows:

  • Define
  • Measure
  • Analyze
  • Improve
  • Control

In this first step, the project team defines the problem or improvement opportunity. The team clarifies the project’s goals, scope, stakeholders, and outcomes. It is important to develop a clear understanding of what needs to be improved and why it is important.

In the critical first phase of project initiation, the project team begins the journey to carefully define the underlying problem or exploit opportunities for improvement. This requires in-depth research to formulate project goals, define scope, identify key stakeholders involved, and outline expected outcomes.

To illustrate, let’s consider the scenario of a software development project that aims to improve the user experience of a popular mobile application. The project team begins by identifying specific weaknesses or areas for improvement within the current application interface. This could be an issue with navigation efficiency, loading speed, or user engagement metrics. By carefully defining these aspects, the team sets clear goals to: B. Reduce user churn, increase time spent in app, and ultimately improve overall customer satisfaction.

Additionally, it is essential at this stage that the team develops a broad understanding of why solving these problems is so important. For example, you can analyze user feedback, conduct market research, and compare competitor products to understand the importance of improving the user experience of your application. This understanding not only serves as a guide throughout the project, but also ensures that subsequent steps are closely aligned with the overall goals and objectives initially set.



Once the problem is defined, the team collects data related to the process being studied. Quantitative data is collected to understand the current state of the process and establish key performance indicators. The accuracy and precision of the measurement system are evaluated to ensure reliable data collection.

After clearly defining the problem at hand, the team begins a comprehensive data collection phase focused on the process at hand. This involves collecting quantitative data to gain insight into the current state of the process and set benchmarks for key performance indicators. An important aspect of this step is to ensure the reliability of data collection by assessing the accuracy and precision of the measurement system.

For example, imagine a manufacturing company that wants to optimize its production line to meet increasing demand while maintaining quality standards. Once various manufacturing performance issues are identified, the team begins collecting data on various aspects of the manufacturing process. This includes quantitative information such as production rate, downtime, error rate, and asset utilization.

For example, teams can use sensors and monitoring devices installed on machines to collect real-time data on production rates and downtime. Additionally, manual observations and measurements can be performed to evaluate factors such as product quality and resource consumption.

At the same time, the team evaluates the measurement system used to collect this data. We ensure sensors are properly calibrated and calibrated regularly to maintain accuracy. Likewise, manual measurement equipment is calibrated and standardized to minimize data collection errors.

Studies can also be conducted to assess the reliability of data collected with these measurement systems. For example, you can compare data collected from different sensors or measurement devices to ensure consistency and reliability.

Overall, this thoughtful approach to data collection and measurement system evaluation ensures your team has a solid foundation of reliable data from which to analyze and make informed decisions about process improvement initiatives.



At this stage, the team analyzes data to identify root causes of process errors or deviations.
Statistical tools and techniques are used to analyze data trends, patterns, and relationships. The goal is to better understand why processes are not reaching desired performance levels and to prioritize areas for improvement.

At this stage, the team conducts a comprehensive examination of the data to identify root causes of any defects or deviations in the process. Using a variety of statistical tools and techniques, the team examines data trends, patterns, and relationships to gain valuable insights. This analysis process is similar to solving a complex puzzle in which a team analyzes data to find why a process is not achieving the desired level of performance.

For example, consider a manufacturing situation where a company is experiencing a higher than acceptable rate of product defects. The analysis phase examines production data, uses statistical methods to identify correlations, and investigates potential factors contributing to errors. This may include variables such as machine settings, raw material quality, or operator performance. By carefully analyzing the data, the team gained a deeper understanding of the complex dynamics occurring in the manufacturing process.

The ultimate goal of this analysis effort is to identify current deficiencies as well as prioritize areas for improvement. By identifying root causes, teams can develop targeted strategies to improve overall process efficiency and performance. This lays the foundation for meaningful, sustainable improvement and ensures that your organization consistently meets or exceeds its performance goals.



Based on the results of the analysis phase, the team develops and implements solutions to address the identified root causes. A variety of improvement techniques and tools are used to optimize processes and eliminate errors. Pilot testing can be conducted to verify the effectiveness of the proposed solution prior to full implementation.

After an extensive analysis phase, the team strategically formulates and implements solutions to identify root causes. This complex process requires the use of a variety of carefully selected improvement techniques and tools to optimize the overall workflow and eliminate system errors. Imagine a manufacturing plant that receives in-depth analysis of the inefficiencies in its production line to find parallels with real-world situations. Based on the information gained from this analysis, the team introduces and tests various techniques, such as lean manufacturing principles or Six Sigma methods, to improve manufacturing processes and solve identified problems. Additionally, before beginning full implementation, teams can conduct pilot testing to carefully test the effectiveness of proposed solutions and ensure that improved processes actually lead to desired improvements and outcomes. This thoughtful, iterative approach not only prevents potential disruptions, but also promotes a culture of continuous improvement within the organizational structure.



The final step is to establish controls to sustain improvement. Control and monitoring systems are in place to ensure that processes remain stable and performance objectives are consistently achieved. Standard operating procedures, training programs, and ongoing data collection are implemented to support continuous improvement efforts.
The final stage of the improvement process involves implementing strong controls to maintain and sustain the improvements achieved. This requires the establishment of comprehensive control and monitoring systems to ensure sustainable stability of the process and consistent alignment with performance targets. Several strategies are taken to facilitate this, including formalizing and adhering to standard operating procedures, introducing structured training programs, and collecting relevant data on an ongoing basis. Together, these elements form a dynamic framework that not only ensures improvements but also promotes a supportive environment for continuous improvement.

For example, consider a manufacturing company that has successfully optimized its production process to increase efficiency and reduce defects. As a final step, the company implements a strict control system, including standardized operating procedures for each production step. At the same time, employees receive regular training to keep up to date on optimized processes and best practices. In addition, a sophisticated monitoring system is incorporated that continuously collects and analyzes production data to detect deviations from established standards. This comprehensive approach ensures reliable production processes, achieves performance goals, and lays the foundation for continuous improvement in productivity and product quality.

Throughout the DMAIC process, Six Sigma teams use a combination of problem-solving methods, statistical analysis, and quality management tools to drive systematic improvement and achieve measurable results. The ultimate goal is to provide a product or service that consistently meets customer needs and minimizes errors and variability in the process.

In the DMAIC (Define, Measure, Analyze, Improve, Control) process, Six Sigma teams take a comprehensive approach that integrates a variety of problem-solving methods, statistical analysis, and quality control tools. This multifaceted strategy contributes significantly to achieving systematic improvement and tangible results. The overall goal is to ensure consistent delivery of products or services that meet customer requirements and minimize errors and variability in the process.

For example, imagine a manufacturing scenario where a Six Sigma team is tasked with improving the production of specific electronic components. During the definition phase, the team clearly describes the problem and identifies potentially high defect rates in the current manufacturing process. The measurement phase uses statistical analysis to quantify the problem and establish baseline metrics.

In the next “analysis” phase, the team investigates deeper into the cause of the error. Use statistical tools such as Pareto charts or fishbone diagrams to identify important factors contributing to deviations and errors. Armed with this knowledge, the team moves to the “advanced” stage and implements targeted changes in the production process. This may include adjusting machine settings, improving quality control protocols, or introducing new technology.

To ensure the continued success of the improvement, the team moves into the “Control” phase. Quality management tools, such as control charts and process maps, are used to monitor and maintain improved processes over time. This iterative approach within the DMAIC framework allows for a continuous cycle of improvement that minimizes defects and increases consistency in the final product that meets or exceeds customer expectations.

Simply put, Six Sigma teams strategically use the DMAIC process to leverage a variety of problem-solving methods, statistical analysis, and quality control tools. This holistic approach not only solves immediate problems, but also creates a framework for continuous improvement, ultimately achieving the goal of delivering a high-quality product or service that consistently meets the needs of our customers.
