chapter 1 Six Sigma Foundation and Principles Flashcards
What is the main purpose of Six Sigma?
To reduce variation in processes to improve quality and efficiency.
How does Six Sigma ensure consistent quality?
By minimizing defects and delivering consistent products and services.
What is the DMAIC framework in Six Sigma?
Define, Measure, Analyze, Improve, Control.
What is the first step in the DMAIC process?
Define the problem or project goals and understand customer requirements.
What is the Measure phase in DMAIC?
Collect data on current processes and establish baselines.
What is the goal of the Analyze phase in DMAIC?
Investigate data to identify root causes of issues.
What happens during the Improve phase of DMAIC?
Develop solutions to address root causes and enhance processes.
** What is the purpose of the Control phase in DMAIC?**
** Implement controls to sustain improvements over time.**
How has Six Sigma evolved from traditional quality management?
** It builds on earlier practices by introducing rigorous statistical methods and focusing on financial benefits.**
** Which key figures influenced the evolution of Six Sigma?**
Deming, Juran, and Ishikawa.
What are some benefits of Six Sigma for organizations?
Enhanced customer satisfaction, reduced costs, increased profitability, and a culture of continuous improvement.
How does Six Sigma help in reducing costs?
By eliminating waste and defects in processes.
What role does Six Sigma play in customer satisfaction?
It ensures higher quality and consistency in products and services.
What are some common statistical tools used in Six Sigma?
Pareto charts, cause-and-effect diagrams, control charts, histograms, scatter diagrams, and run charts.
What is a SIPOC diagram used for in Six Sigma?
To define the scope of processes, including Suppliers, Inputs, Process, Outputs, and Customers.**
** Why are flowcharts important in Six Sigma?**
They help visualize and analyze process steps for better understanding and improvement.
What is the 5 Whys technique used for?
** To drill down to the root cause of a problem by asking “Why?” multiple times.**
What is a Fishbone (Ishikawa) diagram?
A tool used to categorize potential causes of problems to identify the root cause.
What is the key takeaway regarding the reduction of variation in Six Sigma?
** It is central to improving quality and predictability in processes.**
What does the structured approach of DMAIC provide?
A clear and systematic framework for process improvement.
How does Six Sigma’s historical context contribute to its principles?
It extends and refines earlier quality management principles focusing on optimization and financial benefits.
What is the organizational impact of adopting Six Sigma?
Improved quality, reduced costs, increased customer satisfaction, and enhanced profitability.**
