    Skills You Will Build in This ProgramDMAIC, Statistics, and Lean Tools in Practice

    The skills covered in the Green Belt program span all five DMAIC phases, from defining a problem to controlling an improved process. By the end you can scope projects, analyze data, and sustain measurable improvement using Lean and statistical tools.

    Define Problems and Project Scope

    Learn to translate the voice of the customer into critical-to-quality requirements, build a business case and project charter, and map processes with SIPOC so every improvement project starts with a clear, measurable problem.

    Measure Process Performance

    Use process mapping, measurement system analysis, and process capability to quantify how a process performs today. Apply basic Six Sigma metrics such as DPMO, FTY, and cycle time to set a reliable baseline.

    Analyze Data and Root Causes

    Apply descriptive and inferential statistics, hypothesis testing, and patterns of variation to separate real causes from noise, so you target the factors that actually drive defects and delay.

    Improve Processes with Data

    Use simple and multiple regression and designed experiments, including full factorial designs, to model relationships and identify the changes that deliver the biggest, most reliable performance gains.

    Control and Sustain Gains

    Build control plans and use statistical process control charts such as I-MR, Xbar-R, and P charts to monitor processes and hold improvements in place long after a project closes.

    Apply Lean Tools to Eliminate Waste

    Integrate Lean techniques such as 5S, value stream mapping, Kanban, and Poka-Yoke within DMAIC to remove the seven wastes and make processes faster, cleaner, and mistake-proof.
