Six Sigma
Six Sigma is a method used in manufacturing and engineering to make processes more reliable and reduce mistakes. Think of it like a recipe book for making processes better - it uses statistics and data to find and fix problems. Companies use Six Sigma to save money by reducing waste and making their operations more efficient. Similar approaches include Lean Manufacturing and Total Quality Management (TQM). When someone mentions Six Sigma on their resume, it usually means they've been trained in these improvement methods and have experience making processes work better. You might see it written as "6σ" or mentioned alongside terms like "Green Belt" or "Black Belt," which are different levels of Six Sigma training.
Examples in Resumes
Led Six Sigma project reducing waste by 25% in chemical production line

Senior Level Questions
Q: Can you describe a challenging Six Sigma project you've led and its results?
Expected Answer: Look for candidates who can explain a complete project from problem identification to solution implementation, including team management and measurable business results. They should mention data analysis, team leadership, and how they overcame obstacles.
Q: How do you decide when Six Sigma is the right approach for a problem versus other methodologies?
Expected Answer: Strong answers should show understanding of when to apply Six Sigma (complex problems with measurable data) versus simpler solutions, demonstrating practical business judgment and experience with multiple improvement methods.
Mid Level Questions
Q: What tools do you typically use in a Six Sigma project?
Expected Answer: Should mention common tools like process mapping, cause-and-effect diagrams, and data analysis methods. Look for examples of how they've actually used these tools in real projects.
Q: Explain how you would involve operators and technicians in a Six Sigma project.
Expected Answer: Should demonstrate ability to work with front-line staff, gather information from those doing the actual work, and explain technical concepts in simple terms.
Junior Level Questions
Q: What does Six Sigma mean and why is it important?
Expected Answer: Should be able to explain that Six Sigma is about reducing errors and variation in processes, making them more reliable and efficient. Basic understanding of the goal to improve quality is essential.
Q: What is DMAIC and why is it used?
Expected Answer: Should explain that DMAIC (Define, Measure, Analyze, Improve, Control) is the basic problem-solving process in Six Sigma, showing understanding of these basic steps.
