    The Lean Six Sigma Skills You Will Take to WorkFrom Define to Control

    This Yellow Belt training builds practical, job-ready skills across all five DMAIC phases. By the end of the program you will be able to support process improvement projects, work confidently with quality data, and apply foundational Lean tools in your day-to-day role.

    Define Problems That Matter

    You will learn how to scope an improvement problem the Lean Six Sigma way: capturing voice of the customer, identifying critical-to-quality characteristics, building a project charter, and understanding Six Sigma roles. This is the foundation that connects everyday work to measurable business results.

    Measure Process Performance

    Map processes with SIPOC and process maps, and work with core quality metrics such as DPU, DPMO, FTY and cycle time. You will build the habit of basing decisions on data rather than assumptions, the heart of the Measure phase.

    Analyze Root Causes

    Use cause-and-effect (fishbone) diagrams, Pareto analysis and basic statistics to find the real drivers of variation and defects, rather than treating symptoms. You will understand how analysis points teams toward the right improvements.

    Improve and Streamline Work

    Apply Lean concepts including the seven wastes, 5S and value stream awareness to remove non-value-adding steps. You will see how the Improve phase turns analysis into practical, lasting process changes.

    Control and Sustain Gains

    Learn how improvements are held in place using control plans, basic statistical process control, Kanban and Poka-Yoke (mistake proofing). You will understand why sustaining results is as important as achieving them.

    Support Improvement Teams

    Understand exactly how a Yellow Belt contributes to DMAIC projects led by Green and Black Belts, from data collection to process documentation. You will leave ready to add value on real improvement initiatives at work.
