What You Will Master Across the Five DMAIC PhasesFrom Define to Control
This Green Belt training equips you to run the full DMAIC cycle, from defining a problem to sustaining the gains. By the end you can lead practitioner-level improvement projects and apply Lean and statistical tools to real work in Bulgarian operations and services.
Scope and Charter Improvement Projects
You will learn to define improvement projects that matter, building a project charter, capturing the voice of the customer, identifying critical-to-quality characteristics, and framing problems with the Y = f(x) strategy so effort targets what affects performance.
Measure Process Performance with Data
Map processes with SIPOC and value stream maps, build measurement systems you can trust, and calculate baseline metrics such as DPMO, yield and process capability to quantify where a process really stands today.
Analyse Root Causes Using Statistics
Apply descriptive and inferential statistics, hypothesis testing and graphical analysis to separate real causes from noise, so improvement decisions rest on evidence rather than opinion.
Improve Processes with Regression and DOE
Use correlation, simple and multiple regression, and to test changes, model relationships, and identify the settings that deliver measurable, repeatable improvement.
Sustain Gains with Process Controls
Hold the gains with statistical process control charts, control plans and response plans, ensuring improvements stick long after the project closes and performance stays stable.
Apply Lean Tools to Eliminate Waste
Put Lean to work with 5S, Kanban and Poka-Yoke (mistake-proofing), targeting the seven wastes to streamline flow and raise efficiency across operations and services.
