The DMAIC Framework: Analyze, Improve, and Control Phase from Coursera

The course will teach you the competencies and essential skills required to pass the American Society for Quality (ASQ) Certified Six Sigma Green Belt (CSSGB) exam. This course focuses specifically on the last three phases of the define, measure, analyze, improve, and control (DMAIC) framework and will enable you to analyze the root causes of existing issues, implement solutions, and ensure the process's sustainability. You will gain insight into data analysis techniques such as hypothesis testing and regression analysis and be able to develop control plans for process improvement.

By the end of the course, you will be able to:

- Describe the importance of analyzing data and identifying root causes of problems in the process.

- Apply data analysis techniques such as hypothesis testing, regression analysis, and correlation analysis to identify the issues in your process.

- Develop control plans and strategies for sustaining process improvements.

- Use control charts and statistical process control techniques to monitor process performance.

The course offers practical exposure with a peer-graded project that enables you to apply your knowledge in real-world scenarios. The course is for individuals who wish to analyze and solve quality problems and are working in process improvement teams or involved with Six Sigma, lean, or other quality improvement projects.

What's inside

Syllabus

Analyze: Exploratory data analysis (EDA)

In this module, you will learn why exploratory data analysis (EDA) is a critical component of data analysis in various domains, including statistics, data science, and machine learning. It involves examining and visualizing the characteristics of a dataset to gain insights, discover patterns, and identify relationships between variables. It also helps understand the data, identify quality issues, and formulate hypotheses for further analysis. Additionally, you will learn the fundamentals of correlation and linear regression and how to analyze and extract meaningful insights from datasets. This helps to strengthen the foundation for subsequent data analysis and modeling tasks, enabling informed decision-making and hypothesis generation.

Reviews summary

Practical dmaic for process improvement

According to learners, this course offers a practical and insightful dive into the Analyze, Improve, and Control phases of the DMAIC framework, proving highly valuable for Six Sigma Green Belt preparation. Many found the explanations of complex statistical concepts, like hypothesis testing and control charts, clear and easy to follow. The peer-graded project is consistently highlighted as a strong practical component, helping students apply knowledge in real-world scenarios. While largely positive, some pointed out that the pace in certain modules, such as Design of Experiments, felt fast or that more hands-on exercises beyond the peer review would be beneficial, suggesting a basic statistics background is advantageous.
