    Skills You Will Master Across the DMAIC CycleThe Define to Control Toolkit

    This Green Belt program teaches you what you will learn across the full DMAIC method: how to define, measure, analyze, improve and control real processes. By the end you can lead scoped improvement projects and prepare for the exam with confidence.

    Define Projects That Matter

    In Green Belt training you will learn to scope, charter and select improvement projects, capture the voice of the customer, map processes with SIPOC, and tie project goals to cost of poor quality and clear business cases.

    Measure Process Performance

    Build baseline metrics such as DPMO, first time yield and cycle time, create detailed process maps and value stream maps, run measurement system analysis, and assess process capability with real data.

    Analyze Root Causes with Data

    Use fishbone diagrams, multi-vari analysis, inferential statistics and hypothesis testing to separate the vital few causes of variation from the trivial many and find what truly drives defects.

    Improve and Validate Solutions

    Apply simple and multiple regression and designed experiments to test changes, pilot improvements, and confirm that solutions deliver measurable, statistically sound gains before rollout.

    Control and Sustain Gains

    Hold improvements in place with statistical process control charts, control plans, 5S, Kanban and Poka-Yoke mistake-proofing so results last well beyond the project.

    Apply Lean Waste Reduction

    Integrate Lean thinking within DMAIC by identifying the seven wastes, streamlining flow with value stream mapping, and embedding 5S to make processes faster and leaner.

    General

    What is the Lean Six Sigma Green Belt certification?

    Is the Green Belt certification worth it in Tulsa?

    Yes. Green Belt roles in Tulsa average around $112,500 a year, and aerospace, energy, healthcare and manufacturing employers actively hire certified process improvement professionals. The credential signals you can deliver measurable savings, a strong return on a short training investment.

    Who should take Lean Six Sigma Green Belt training?

    It suits quality analysts and engineers, operations and manufacturing professionals, team leads, and anyone moving up from a Yellow Belt or building toward a Black Belt. No specific role is required, just an interest in leading data-driven improvement.

    Do I need prior experience or a Yellow Belt first?

    No. There are no formal prerequisites for the Green Belt. Real-world experience and prior Lean Six Sigma exposure are helpful but not mandatory, and the training builds the concepts from the ground up.

    How long is the Green Belt certification valid?

    The credential carries current status for three years from your certification date. To maintain it, you complete the recertification exam before the status elapses, keeping your designation active.

    Pricing

    The fee covers 32 hours of instructor-led training, courseware aligned to the IASSC Green Belt Body of Knowledge, practice questions, mock exams, templates, learner support and a course completion certificate. Request a quote for current pricing.

    Exam

    What is the format of the Green Belt exam?

    The exam has 100 questions in a closed-book format, using multiple-choice and true or false questions, with a three-hour allotted time. Some exam forms include up to 10 additional unscored questions.

    What is the passing score for the Green Belt exam?

    You must achieve a minimum of 385 points out of 550. Questions are spread roughly evenly across the five DMAIC phases, so aim for broad mastery rather than a single area.

    How is the Green Belt exam delivered?

    You can sit the exam through an online proctored, on-demand system available around the clock, or at a Pearson VUE test center. There are no eligibility prerequisites to schedule it.

    What is the exam application process?

    You purchase an exam voucher from the governing body's order portal, choose online proctored or test-center delivery, then schedule and sit the 100-question exam. Our team guides you through registration and readiness.

    What if I do not pass the exam on the first attempt?

    You can purchase another voucher and reschedule the exam. Our preparation includes mock exams and practice questions designed to remove surprises and build your confidence before exam day.

    Course Content

    Can a beginner take this Green Belt course?

    Yes. The course assumes no prior Six Sigma background and builds from the fundamentals, so beginners and experienced professionals alike can follow it. Hands-on exercises reinforce each DMAIC phase.

    What topics does the Green Belt training cover?

    The training covers the five DMAIC phases, Define, Measure, Analyze, Improve and Control, alongside applied statistics, hypothesis testing, regression, and Lean tools such as 5S, value stream mapping and Poka-Yoke.

    What is the difference between Green Belt and Black Belt?

    Green Belt is the intermediate level, where you support or lead scoped improvement projects. Black Belt is advanced, covering deeper statistics and leading complex, full-time projects while mentoring Green Belts.

    Are practice tests and study materials included?

    Yes. You receive courseware, practice questions, full-length mock exams and downloadable templates and references, all mapped to the Green Belt Body of Knowledge to support your revision.

    How many hours is the training and what format is it?

    The program provides 32 hours of instruction, delivered as live online or classroom training, with self-paced options also available. Schedules can be intensive or spread across more days to suit you.
