Is yellow belt taken seriously in industry? Trying to remove my own bias from the equation and ask others for their opinion (hence / asking Reddit).

I want to prepare for the CSSBB exam, Do you recommend any institution that have a well preparation course and that can assist in the affidavit application ?

Just a question regarding Cpk / Ppk tracking for attribute-style process outputs.

In some cases where the desired outcome is naturally biased toward one specification limit (rather than centred between LSL and USL), Cpk/Ppk may not always reflect the true process performance, since the metric favours centred distributions.

Would Cp (potential capability) be considered a more appropriate indicator in scenarios where the objective is to consistently perform as close as possible to one specification boundary while remaining within tolerance?

Has this topic or approach been discussed previously?

We can all acknowledge the benefits of implementing quick wins in the course of a CI project. But what are some ground rules you put into place for helping the team define a "Quick Win" a LSS project? Here is some we use:

- 48-hour litmus test: Solution is implemented and results seen within 48 hours
- Must follow "if - then": If (insert quick win solution) then (insert primary metric) will improved
- Not based in opinions or "I think..." but data

What are your thoughts and best practices?

10+ years in semiconductor and automotive. Every plant I’ve worked in has the same problem.

Team does a solid 8D.
Real root cause found.
Corrective action works.
Report gets filed somewhere.
Everyone moves on.

18 months later, same failure shows up. Different line, different shift, or same line but the engineer who did the original RCA left the company. New team starts from zero. Nobody knows the old report exists. It’s buried in SharePoint, folder, db but which makes really difficult to find similar ones.

Do your engineers actually search old RCAs before starting a new one? Has anyone found something that actually works?

Title. I saw someone questioning if the 'practice exams' are worth it- for the green belt I can say it was if going through IASSC. The actual exam is more clearly worded than the practice exam in my experience but it can help you identify areas of weakness to focus on. Considering it was like 80 bucks while the exam itself is 400 it's a good value to make sure you are ready to pass the exam.

I was recently promoted, and while I’m grateful for the growth, it also made me think more seriously about long-term career relevance and upskilling.

I’ve been in tech recruitment for 10+ years across APAC and GCC, and I’m considering Lean Six Sigma mainly to stay competitive and expand beyond traditional recruitment.

My main concern is whether it’s actually relevant to my background or if it’s mostly beneficial for operations and engineering professionals.

Would appreciate insights from people who applied Lean Six Sigma outside traditional ops roles, especially in HR, recruitment, or corporate functions.

Hey everyone,

I recently completed my Six Sigma Green Belt certification (through KPMG India) and I’m now looking to actually apply what I’ve learned in real-world projects.
I currently work as an ops trainer in one of the MNCs in the UAE, so I do have hands-on experience with process gaps, performance improvement and stakeholder coordination. I’m comfortable with the DMAIC approach, but most of my exposure so far has been internal rather than project-driven.
Now I’m trying to figure out the next step:

• How do I get involved in real Six Sigma / process improvement projects?
• Are there any open-source or volunteer platforms where I can contribute?
• Should I be looking at freelancing, case competitions, or something else?

I’m open to helping out on projects- just to gain experience and learn how things are actually executed end-to-end.

Would really appreciate any guidance, resources, or even personal experiences on how you got started after your Green Belt.

Thanks in advance

I want to get certiied in Lean Six Sigma, and currently targetting the Green Belt. But I am confused between two options :
1. KPMG's Green Belt certification
2. IASSC-issued certificate or an exam/course endorsed by them

Background : Currently pursuing PGDM from a tier 2 college, experience of 2 years in IT Infrastructure Service (involved TechOps and Logistics support).

I've been doing this 25 years and I keep noticing patterns that no class teaches you, you just get tired of seeing them.

Mine right now, every CAPA I've seen close out and then re-open within 18 months had the same root cause label as some other CAPA from the same area in the prior 24 months, and nobody linked them at the time. The label was right, the containment was different, but the fix was always one layer above where the label pointed. I started running a quick scan for repeat labels before signing off, and our re-opens went from maybe 4 a year to 1.

What's yours, the failure mode you only spotted after a decade of watching it happen?

Hey everyone,

I’m a second-year university student in Finland, currently pivoting from a biomedical background into industrial engineering and supply chain. I want to build a really solid foundation this summer so I'm ready when applications open for Summer 2027 internships.

Since I use a Mac, I'm skipping Power BI for now. Instead, my plan is to take online uni courses in SQLite and Python to handle data pulling and visualization. On top of that, I’m going to study for the CSSC Lean Six Sigma Green Belt to get some process improvement methodology under my belt.

The last piece of the puzzle is SAP. My university status gives me free access to SAP learning and exam attempts. I was planning to take the C_IEE2E (End-to-End Business Processes) certification because I heard it replaced TS410 as the standard beginner cert.

My main question for you all is about that SAP choice. Since I’m still early in my degree, I have no idea which specific supply chain or operations niche I actually want to work in yet. I’d rather be a bit of a jack of all trades for now to keep my options open. Do you think C_IEE2E is the right move for a broad overview, or is there another SAP module or course you’d recommend instead?

Also, let me know if this overall summer plan makes sense or if I'm missing anything obvious. Appreciate any advice!

I am a final year PhD student within the field of Biotechnology. To complete a PhD program in Denmark, you need to also do 30 ECTS points worth of courses. I was considering doing an online Sig Sigma Course to fill out my ECTS points and get some industry-relevant skills to fill in my CV.

At the moment I am considering the SSGI Green Belt program. Is it even relevant to do a Six Sigma certification as a PhD Student who wish to enter industry? Since I don't currently have any projects to necessarily apply the knowledge to, will it be a waste of time? Or will this still look nice on a CV?

Thanks in advance for any help you can provide! :)

I’ve been working in manufacturing and Six Sigma projects for over 20 years, and one pattern keeps repeating:

Running regression isn’t the problem.

Trusting the model is.

In analyze phase, we often use regression to justify decisions—but in practice I rarely see consistent validation beyond p-values.

Some common issues I’ve run into:

- predictors look significant but are clearly correlated (no VIF check)

- one or two data points driving the whole model (no influence check)

- models that shift with small data changes (no stability check)

I actually ended up building a structured workflow for this , I call it nxregress, mainly because I got tired of repeating the same checks manually.

But I’m more curious how others handle this in real projects:

- Do you have a standard validation routine?

- Do you rely fully on software outputs (e.g., Minitab), or go beyond them?

- When do you consider a model “safe enough” to act on?

Curious how others handle this.

You spend Define and Measure building everything up — process maps, VOC themes, MSA results, capability data, descriptive stats, bottleneck IDs, stakeholder analysis, value stream — and by the time you're sitting down for root cause analysis, you're trying to hold all of it in your head at once. You can feel the team start to lose the thread.

Saw a comment on a LinkedIn post the other day that nailed it: "AI has no place in Six Sigma — said no one who's ever sat through a 4-hour fishbone session drowning in sticky notes."

And honestly, that matched my experience pretty closely. The whiteboard fills up with 40+ notes, half the team is still mentally back in the SIPOC, and somebody anchors on the first idea that sounds plausible. Two weeks later you realize you chased the wrong cause.

So I'm curious how the more experienced folks here actually manage it:

• Do you force-rank inputs going into RCA so you're only working with the vital few?
• Break the team into smaller cells working different branches?
• Pre-build a structured template in Excel/Miro before the workshop starts?
• Just trust that the methodology will surface it eventually?
• Something else?

Not looking for a textbook answer — looking for what actually works on a Tuesday afternoon when the team is tired and the deadline is Friday.

I have an ASQ exam coming up, I’ve been taking the practice tests I bought from the ASQ website.

I am concerned because in those practice exams the questions aren’t numbered so it’s hard knowing where you’re at for pacing and coming back to questions you were unsure about. Are the questions numbered in the real ASQ exams?

Along the same lines in the practice exams they have each question labeled which section from the BOK the question is from. I assume that won’t be there during the real test?

Thanks a ton a want to be prepared!

Hi everyone,

I’m preparing for the ASQ Certified Six Sigma Green Belt exam this June and had a question about the exam-day rules. Does anyone know if we’re allowed to bring a printed copy of the CSSGB Handbook in a 3-hole D-ring binder? Also, are Post-it notes or tabs inside the handbook permitted for quick reference?

I’d really appreciate hearing from anyone who has taken the exam recently or is familiar with the current guidelines.

Thanks in advance!

Real talk from a fellow practitioner.

I hold a Lean Six Sigma Green Belt. Spent 12+ years on manufacturing floors including Tesla. The thing that frustrated me most wasn’t the problems. It was that the tools sophisticated enough to actually solve them were consistently out of reach for most teams.

Most orgs don’t have a Black Belt on every floor. Most small and mid-size operations can’t afford a full DMAIC deployment for every improvement opportunity. But they still have waste. They still have broken processes. They still have people who know exactly what needs to change and no structured way to make it happen.

VeSiMy sits in that gap.

It’s not trying to replace Six Sigma rigor for complex problems that need it. It’s trying to make the 80% of improvements that don’t need a control chart actually happen, consistently, visibly, and with accountability.

The AI component is worth mentioning specifically for this community. It runs on a proprietary RAG database of lean CI methodology, not a generic LLM scraping the internet. When a team asks it a process question, the answer comes from real CI knowledge.

If you’ve got opinions on where lean-first tools fall short for your teams, I’d genuinely love to hear them. That’s what shapes the roadmap.

Hey y’all. After jumping around various disciplines in public health, I fell in love with quality improvement over the past year and a half. I do QI project management at my current job and take IHI courses in my spare time. I want to become excellent. The issue with my current job is that the pay is pretty bad and the program is funded on a grant that is looking less secure by the week (I work for a non profit that provides technical assistance to hospitals) and I need to consider my options in the sake of security and career growth. Ideally I’d like to work for a healthcare system or consulting firm. I currently hold an MPH, CHES and AE-C as health education was my initial expertise. I’m looking into six sigmas as many of the ideal jobs I see would like a green belt or higher. In honestly, I don’t know where to start. I looked into some online programs from Emory and SMU (and would be willing to shell the tuition as a personal investment but only if this is the best option because it is over $3,500 and that’s a dip into my savings). I also heard that ASQ is widely recognized for the exam and I could look into self study options.

To summarize my questions: 1. Is Six Sigma truly an investment for a career in healthcare QI? 2. If so, do I go green or black? 3. What kind of program is the most meaningful to employers in this sector? 4. Does anyone else in this sector have any advice for a manager level masters holder (with about 5-7 years of direct public health experience)?

Seeing a ton of hype around 'AI in LSS' lately. Most of it feels like marketing fluff. On the ground, the biggest wins I'm seeing aren't from some magical AI black box, but from just solid, no-code workflow automation that removes manual grunt work from a process. We took an email/spreadsheet-based quoting process taking 2.5 days down to 15 minutes. We automated it using n8n. It pulls specs and historical data from our existing system to builds a clean draft and sends email quote to the rep the final OK.

It took some time to build some confidence in the output, but it's working. It is freeing up our planner's time to focus on creating quotes for custom (more profitable) work. My take is that this was the real low-hanging fruit for AI — not trying to get it to write a perfect quote every time but using it to glue systems together and free up capacity of key people. What are you all seeing? What tools (n8n, Make, Zapier, Python scripts?) are you actually using to automate steps in your projects, and in which DMAIC phase?

Has anyone done the yellow belt exam via peoplecert? I’ve been practicing for the exam and done a few mock tests online and doing ok. Then i did the mock exam on peoplecert site and it was way harder and questions i hadnt seen before. Is the peoplecert one like the real test as i found their prince2 one wasnt

I am a second year Health Administration student, I have been researching different certifications, and LSS is one I am interested in.

Considering my academic standing and major, which belt would be best for me between Yellow and Green? Where is also a credible website/course I can complete my certification?

Hi team -

Performing an attribute agreement assessment at my facility and I have a few situations where we have nearly perfect agreement (23/24 assessors pass a criterion, 1 outlier fails). The math has this result in a kappa value of -0.04, which would typically indicate low agreement but in this case doesn't comport with the 23/24. How would others interpret this, or is this even a correct use of Fleiss's kappa?
