What are the core phases of Six Sigma and what does each phase focus on?
Six Sigma’s core phases are Define, Measure, Analyze, Improve, and Control (DMAIC). Define sets project scope and CTQs; Measure establishes current performance and DPMO; Analyze identifies root causes; Improve implements changes; Control sustains gains through monitoring and limits, collectively known as DMAIC.
How is Cost of Poor Quality (COPQ) used in Six Sigma projects?
COPQ quantifies the financial impact of defects and failures to prioritize improvement opportunities and justify projects. Teams use COPQ analysis to link process problems to profitability and select initiatives with measurable financial outcomes; COPQ is a primary topic in the PSL - Six Sigma Introduction.
How do you measure defects and what is DPMO?
Defects are measured using Defects Per Opportunity metrics; DPMO equals Defects Per Opportunity (DPO) multiplied by one million. DPMO provides a standardized view of process performance across scales and is covered in the PSL - Six Sigma Introduction as a key measurement tool.
What are the different Six Sigma training levels and typical responsibilities?
Training levels include Master Black Belt (MBB), Black Belt (BB), Green Belt (GB), and Yellow Belt (YB). MBB mentors and trains others; BB leads projects; GB participates in and supports projects; YB learns basic tools and applies them, as described in the PSL - Six Sigma Introduction.
What should I look for when buying a Six Sigma introductory slide deck for my team?
Look for clear coverage of DMAIC, COPQ, DPMO, CTQs, variability and limits, plus practical templates such as a project charter, data collection plan, process mapping tools, and an implementation plan. These specific deliverables appear in the PSL - Six Sigma Introduction.
Are premade Six Sigma templates useful compared to building materials in-house?
Premade templates can provide ready formats for essential artifacts—project charters, data collection plans, process maps, implementation plans—and often include customization guidance to adapt to specific organizational metrics. The PSL - Six Sigma Introduction lists these templates and customization tips, such as adapting the project charter template.
I need to run a half-day introductory Six Sigma workshop for managers—what agenda should I use?
A practical agenda includes a 60-minute overview of Six Sigma principles and benefits, a 90-minute DMAIC deep dive with a group exercise applying DMAIC to a sample project, and a 45-minute COPQ analysis session to quantify quality costs, matching the suggested workshop agenda in the PSL - Six Sigma Introduction.
We have high variability in a manufacturing process; which Six Sigma tools should we start with?
Begin with process mapping to visualize flow, measure variability and specification limits, identify CTQs, then calculate defect metrics like DPMO to quantify performance before applying DMAIC to reduce variation. The PSL - Six Sigma Introduction covers variability, limits, CTQ, and process mapping tools.
