Lean Six Sigma training - which route is right for you?

---

Yes. ILSSI is an international Lean Six Sigma accreditation body with partners and learners worldwide. ILSSI‑certified belts are recognised by many employers across sectors. 

Yellow Belt is an introduction to Lean Six Sigma – ideal if you’re supporting improvement projects or want to understand the language and tools.
Green Belt is for people who will lead projects, go deeper into problem‑solving and data, and take more responsibility for delivering change. 

No for Yellow Belt.
For Green Belt, it helps to have some experience of your organisation’s processes and data, but you don’t need to be a statistician or have a technical background. 

Flow offers flexible delivery options:

• Self-paced online learning
• Live online sessions
• In‑person delivery at your site or chosen venue
• Blended programmes that combine self‑paced online learning with live workshops
   

For organisations, I design the format around your teams, locations and shifts.

As a guide:

• Yellow Belt: typically 2 days of live training (or equivalent split into shorter sessions).
• Green Belt: typically 5 days of live training (or equivalent split into shorter sessions), plus time to work on a project if included.
   

Self‑paced courses can be taken in smaller chunks, so you can fit them around your role. Time to completion is 6-month, with extensions awailable.

For many learners and organisations, linking training to a real project is very valuable.

• For individuals, I strongly encourage applying the tools to a real process, and I can support you with coaching.
• For organisations, I can build project work into the programme so participants deliver measurable benefits as they learn.

Yes. For in‑house programmes we tailor:

• Examples and case studies
• Exercises and discussions
• Project selection and support
   

Your people work on familiar processes and issues, not generic case studies.

Yes. If you’re booking multiple places or an in‑house cohort, I can offer group or corporate pricing.
Share how many people you’d like to train and I’ll recommend the most cost‑effective option. 

 You’re not left on your own. Support can include:

• Q&A during and between live sessions
• Coaching calls for self‑paced learners
• Email or online support for clarifying tools, exam questions or project steps
   

We’ll agree the level of support that’s right for you or your organisation.

For in-person training,  exams are delivered online under ILSSI rules.
You’ll receive clear guidance on the process and practice questions in advance so you know what to expect. 

For self-paced learning there are quizzes after each module, but no exam

For self‑paced courses, you keep access to the online learning materials for a defined period, so you can revisit content before and after your exam.
For organisational programmes, we can agree access length and options for future cohorts. 

Yes. Lean Six Sigma is about structured problem‑solving in real processes. We explain tools in plain language and use simple, practical examples. For Green Belt we use data, but we focus on understanding and applying concepts, not advanced maths. 

 The methods apply across many sectors, including:

• Logistics and supply chain
• Operations and shared services
• Procurement and back‑office functions
• Scientific, technical and research environments
• 
  

I encourage participants to bring their own processes and examples, so learning is directly relevant to their work.
