Lean Six Sigma Yellow Belt
Build the proof. Earn the credential. Change the outcome.
Applied basics with a difference: you do not sit an exam to prove you understand Lean Six Sigma — you build a 20-artefact Proof Portfolio on a real problem you chose, and finish with a Mini-A3 you can open in front of any employer. The portfolio is the certification evidence.

Who it's for
Students, early-career professionals, SME operators, office and administrative staff, and entrepreneurs. No prior Lean or statistics knowledge is required — every concept is taught across three real-world contexts: formal SME, office / admin, and informal / entrepreneurial.
What you'll master
Run a full DMAIC cycle on a real process in your own workplace or community.
Assemble a Proof Portfolio of 20 structured artefacts — from charter to control plan.
Turn Voice of Customer into Critical-to-Quality requirements you can measure.
Map processes with SIPOC and swimlanes to expose waste and bottlenecks.
Visualise performance with check sheets, Pareto charts and simple statistics.
Find and verify root causes with fishbone diagrams, 5-Whys and stratification.
Sustain gains with control plans, KPI dashboards and daily-management routines.
Replace every vague claim with documented, quantified before-and-after proof.
The curriculum
| Module 0 — Foundations | Yellow Belt scope, the DMAIC overview and the Proof-Portfolio mindset: Claim vs. Proof. |
| Module 1 — Define | VOC, CTQ trees, problem & goal statements, scope, SIPOC, RACI, and a one-page Project Charter. |
| Module 2 — Measure | Data collection plans, check sheets, baseline performance and descriptive statistics. |
| Module 3 — Analyze | Pareto, fishbone, 5-Whys and stratification to isolate verified root causes. |
| Module 4 — Improve | Effort–impact matrices, 5S, standard work and PDCA to design and test solutions. |
| Module 5 — Control | Control plans, response plans, KPI dashboards and the capstone Mini-A3. |
You'll walk away with
A 20-artefact Proof Portfolio applied to a real problem
A capstone Mini-A3 — the single-page story you bring to interviews and appraisals
Assessment
Portfolio-based. The 20 artefacts, locked in phase by phase across DMAIC, are the evidence, supported by short concept checks. Passing standard is a complete, quality-assessed portfolio.
