LEAN SIX SIGMA Green BELT practice test with complete verified solutions 2024 latest update

What is Six Sigma? -Problem Solving Approach -Use statistics to prioritize, make decisions, develop innovative solutions -Focus on eliminating variance Benchmark Measures of Six Sigma -Variation -Quality -Process Capability -Performance Six Sigma Normal Curve 1 Sigma- 69% 2 Sigma -69.15% 3 Sigma-99.32% 4 Sigma- 99.38% 5 Sigma- 99.98 6 Sigma-99.999998% Fundamentals of Six Sigma Any variance can be: 1.Identified 2. Quantified 3. Eliminated DATA DRIVEN DFSS-Design for Six Sigma Levels of Six Sigma 3 Sigma-Just do it improvement based in logic or intuition 4 Sigma- Low hanging fruit, local processes, apparent 5 Sigma- Majority of opportunities, clearly define, look for design improvement 6 Sigma-Game changing, redesign for more saving, DFSS Is Six Sigma Right for Everyone No! Intuition and simple problem solving Six Sigma Management Pyramid (top to bottom) Champions-advocate Process Owners- managers Green Belt Black Belt Master Black Belt Voice of Customer -who is the customer -acceptable output -inside bounds of lines on bell curve Voice of Process -Limits of process -independent of VOC -whole bell curve Defects -Define by the customer -Outside control limit (lines on bell curve) -Measurable Control Limits -Specs that define acceptable range, anything outside is defect CTQ critical to quality characteristics: -Service -product -process DMAIC Define-identify VOC, VOP Prob Statement Measure- Analyze Improve Control-control plan How are processes created? Repetition Problem Solving Process 1)Practical Problem 2)Statistical Problem 3)Statistical Solution 4)Practical Solution How Should Bell Curve Look Skinny with little to no tails Problem Statement Fundementals -Clear -Concise -Actionable -Begins defining defect Maybe refined based on new info DMAIC is a Funnel The further in the process you are the process input variables (PIV or X) you should consider by IC you should only use Key Process Input Variables (1-6) Variation Variation=precision=less spread NOT Accuracy=Centering=still defects 12 Steps of DMAIC DEFINE -Select Output Characteristics -Define Performance Standards MEASURE -Validate Measurement System -Establish Process Capability ANALYZE -Define Performance Objectives -Identify Variation Sources -Screen Potential Causes IMPROVE -Discover Variable Relationships -Establish Operating Tolerances -Validate Measurement System CONTROL -Determine Process Capability -Implement Process Controls Define Phase Deliverables -project charter -team -stakeholder analysis -process map -SIPOCS diagram -VOC, VOP, CTQ Six Sigma problem solving approach Y=f(x) A process is defined by measurable Y affected by know inputs X Customer Tree -Defines key measurable characteristics of a process -Converts customer wants to CTQ AIM Statement -Defines what project is trying to do -SMART Goal -Specific -Measurable -Attainable -Realistic -Timely Project Scope Defines which part of process will be investigates -clear beginning and end Exclude: -anything intentionally excluded -business not included -related issues not in the time frame
