Lean Six Sigma & Process Improvement: Zero to Job-Ready

Lean Six Sigma & Process Improvement: Zero to Job-Ready

Six Sigma Green Belt skills: DMAIC, root cause analysis, SPC and control charts in Excel, with a real-world case study
Last updated 10/2026
English

What you'll learn

  • Lead a complete Lean Six Sigma project from a vague complaint to a validated, lasting result, using the DMAIC roadmap step by step
  • Map any process the way it really runs, and expose the hidden waiting, rework and workarounds that official procedures leave out
  • Spot all 8 wastes of Lean (DOWNTIME) on a real shop floor or in an office, and build a value stream map that shows where time is lost
  • Calculate DPMO, sigma level, Cp and Cpk in Excel to measure how good a process really is, with no expensive software needed
  • Turn customer complaints into measurable requirements, and write a project charter that a senior sponsor will sign
  • Check that your data can be trusted with Measurement System Analysis and Gage R&R before you build decisions on it
  • Find the real root causes with Pareto charts, fishbone diagrams, the 5 Whys and bottleneck analysis, instead of guessing or blaming people
  • Prove causes with hypothesis tests, chi-square and regression in Excel, explained in plain English, one step at a time
  • Design solutions that stick: mistake-proofing (poka-yoke), flow and pull, kanban, and FMEA to catch risks before launch
  • Plan and run a pilot that proves your solution works, with success criteria, a comparison group and a rollback plan
  • Monitor processes with control charts (I-MR and p-charts) and tell real problems from normal variation, so you stop overreacting
  • Make improvements last with standard work, 5S, visual management and a control plan that a process owner can run
  • Handle resistance, skeptical managers and projects that go off track, the real-world skills that decide whether improvements survive
  • Build a portfolio-ready A3 storyboard from a full end-to-end case study you can present confidently in job interviews
  • Prepare for Green Belt certification, with content aligned to the ASQ CSSGB Body of Knowledge and a clear comparison of ASQ and IASSC
  • Plan your first 90 days in a process improvement role, and avoid the early-career mistakes that hold new practitioners back

Description

This course contains the use of artificial intelligence

Master Lean Six Sigma and process improvement from zero, with Six Sigma Green Belt-level skills, the DMAIC method and step-by-step statistics in Excel.

Every organization has processes that quietly lose money every day: orders that ship late, applications that bounce back, patients who wait for hours, defects nobody can explain. The people who can find out why, and fix it for good, are some of the most valued people in any business. This course shows you exactly how to become one of them.

You won’t just memorize tools. You’ll use every one of them on a single realistic project, from the first customer complaint to a validated, lasting result.

A real project, from first complaint to final result

You’ll step into the role of a newly hired Continuous Improvement Analyst at Northgate Fulfillment, a busy fictional e-commerce warehouse. Its biggest client is losing patience. Orders are shipping late, the wrong items are going out, peak season is weeks away, and a major contract is up for review.

Guided by an experienced Black Belt mentor, you’ll work through the full DMAIC roadmap (Define, Measure, Analyze, Improve, Control) one phase at a time. You’ll map the real process, measure the baseline, prove the root causes, pilot the solutions and lock in the gains. You’ll build a real project document at every stage, and you’ll finish with a one-page A3 storyboard you can show employers.

By the end of this course, you’ll be able to:

  • See any process as it really runs, and spot the waste, waiting and rework hidden inside it

  • Measure performance honestly, and know when your data can’t be trusted

  • Find the true root cause of a problem and prove it with data, not opinions

  • Design improvements, test them safely in a pilot, and know whether they really worked

  • Tell a real problem from normal variation using control charts, so you stop overreacting

  • Make gains last with standard work, visual management and a clear control plan

  • Win over skeptical managers and recover projects that go off track

  • Present your work confidently in a job interview using a portfolio-ready A3

The complete Lean Six Sigma toolkit

  • Lean: the five Lean principles, the 8 wastes (DOWNTIME), process mapping, value stream mapping, flow, pull and kanban, 5S, Kaizen and PDCA.

  • Define and Measure: Voice of the Customer, CTQ trees, SIPOC, project charters, operational definitions, sampling, Gage R&R, and process capability (Cp and Cpk).

  • Analyze: Pareto charts, fishbone diagrams, the 5 Whys, bottleneck and takt time analysis, t-tests, chi-square tests and regression.

  • Improve and Control: poka-yoke, FMEA, pilot design, I-MR and p-charts for statistical process control (SPC), control plans, and validating savings.

Why students choose this course

  • Statistics without fear. Every calculation starts with the decision it helps you make, then is worked through slowly in Excel. You don’t need Minitab or any paid software.

  • Depth where it matters. Capability, hypothesis testing, regression and control charts each get a full lecture, not a passing mention.

  • The people side of improvement. Most courses skip it: handling resistance, working with sponsors, and building a continuous improvement culture.

  • Aligned to the ASQ Certified Six Sigma Green Belt (CSSGB) Body of Knowledge. You also get an honest comparison of ASQ and IASSC certification paths, so you can choose the right one for you.

  • Career guidance. You’ll learn real job titles, what employers expect in your first 90 days, and how to turn your project into evidence.

Built for beginners, deep enough for professionals

No prior experience, degree or advanced math is needed. Every term is defined before it’s used, every formula is explained in plain English, and every lecture moves the project one step forward. The project is set in a warehouse, but you’ll also see examples from hospitals, banks and online retail. These methods work anywhere work flows through steps.

Start your first improvement project today

Automation can make a process faster, but it can’t make it right. That still takes someone who can see a broken process, find the real cause and fix it so it stays fixed.

Enroll now. By the end of this course, you’ll know how to lead your first Lean Six Sigma project from start to finish.

Who this course is for:

  • Complete beginners who want a practical, job-ready path into continuous improvement, operations or quality, with no prior experience or degree required
  • Professionals in operations, logistics, healthcare, banking, manufacturing or customer service who want to fix the broken processes they deal with every day
  • Team leaders, supervisors and managers who want to solve recurring problems with evidence instead of overtime, guesswork or blame
  • Aspiring Green Belts preparing for ASQ or IASSC certification who want to understand the tools deeply, not just memorise them
  • Career changers aiming for roles such as Continuous Improvement Analyst, Process Improvement Specialist or Operational Excellence Coordinator
  • Project managers and business analysts who want a proven, data-driven method to add to their toolkit
  • Anyone who’s nervous about statistics but wants to learn it the friendly way: in Excel, step by step, always tied to a real decision
