Anyone Can Buy a Belt. Ask What They Have Actually Fixed.

Choosing a Lean Six Sigma consultant in the Durham Region is harder than it should be, and here is an uncomfortable fact about this field: the title is unregulated. Nobody owns the phrase Black Belt, there is no provincial licensing body for process improvement, and a person can complete a weekend online course and legitimately put those words on a business card. That is not a scandal, it just means the burden of judgment falls on you.

So this article is written to help you evaluate anyone, including me. I hold a Lean Six Sigma Black Belt and have spent 35+ years in senior executive roles at Honeywell, Johnson Controls, and Armstrong Fluid Technology, and the questions below are the ones I would want a business owner in Durham Region to ask before signing anything.

What Does a Black Belt Certification Actually Require?

This is where most buyers are misled, because the same two words mean wildly different things depending on who issued them. At the rigorous end, the American Society for Quality requires candidates for its Certified Six Sigma Black Belt to have completed two projects with signed affidavits, or one completed project plus three years of full-time paid work experience in the Body of Knowledge, and to pass a lengthy examination. Internships and coursework do not count toward that experience requirement. Verified on the ASQ site 22 July 2026.

At the other end, some providers issue a belt after a short online course with no project requirement and no verified workplace experience at all. Both people can accurately say they hold a Black Belt. The document tells you nothing until you know which kind it is.

So ask the plain question: who issued it, what did it require, and were completed projects part of the requirement. Anyone legitimate will answer immediately and without irritation.

What Should You Ask Before Hiring a Lean Six Sigma Consultant?

1. Tell me about a process you personally improved. Not a project you supervised or a client you advised. One you were in the room for, with the before number and the after number.
2. What happened eighteen months later? This is the question that separates practitioners from presenters. Gains that evaporate after the engagement ends are the normal failure mode, and an honest person will tell you about one that did not hold and why.
3. Who issued your certification and what did it require? Covered above. Listen for specifics rather than a brand name.
4. How will you build capability in my team? If the answer does not include training your own people, you are buying a dependency rather than an improvement.
5. What will you need from my leadership team? Anyone who says very little is either inexperienced or telling you what you want to hear. Sustained change requires visible leadership involvement, and a good practitioner will say so early.
6. What would make you tell me not to proceed? A person with judgment has a list. A person selling a package does not.
7. How do we measure whether this worked? Agree the measures before the work starts, in numbers you already track. Measures invented afterward tend to flatter the result.

When Do You Not Need Outside Help?

Plenty of situations do not warrant hiring anyone, and it is worth saying so plainly.

If you have one obviously broken process and you already know what is wrong with it, map it with your own team and fix it. The tools are not secret. If your real constraint is pricing, demand, cash flow, or a piece of equipment at end of life, process improvement will not touch the actual problem. If nobody in your leadership team has time to be genuinely involved over several months, wait until they do, because an engagement without leadership attention reliably produces a report and no change. And if you already have a capable internal person with the mandate and the time, back them instead of hiring around them.

Outside help earns its cost in narrower circumstances: when you have tried and the gains did not hold, when the problem crosses departments that do not cooperate easily, when you need capability built rather than a single fix, or when you want an experienced outside read on where the largest waste actually sits.

What Are the Warning Signs?

• A guaranteed outcome. Nobody can guarantee a result that depends on your people, your data, and your follow-through. A guarantee is a sales device, not a forecast.
• A quote before any questions. Pricing a process improvement engagement before understanding the process means the number came from a template.
• Certification as the entire pitch. If the credential is the headline and results are the footnote, notice the ordering.
• No interest in your leadership team. Someone who plans to work only with the frontline is planning for gains that will not hold.
• Vagueness about past work. Confidentiality is real and limits detail, but a practitioner can always describe the shape of a problem and what changed.
• Selling software first. A system purchased before the process is understood usually automates existing waste at higher cost.

Frequently Asked Questions

How do I choose a Lean Six Sigma practitioner?

Verify three things in order. What they have personally fixed, with the before and after measures and what happened a year later. Where their certification came from and what it required, since standards vary widely between issuing bodies. And whether they will build capability inside your team rather than creating a dependency. Delivered results matter far more than the credential itself.

Is a Black Belt certification regulated in Ontario?

No. There is no provincial licensing body for Lean Six Sigma, and the title is not legally protected. Requirements depend entirely on the issuing organization. The American Society for Quality, for example, requires completed projects with signed affidavits or a completed project plus three years of full-time paid experience, while some providers issue a belt after a short course with no project requirement at all.

When do I not need outside help?

If you have one broken process and already know what is wrong, map it with your own team. If the real constraint is pricing, demand, cash flow, or failing equipment, process improvement will not address it. If your leadership team has no time to be involved over several months, wait. And if you have a capable internal person with the mandate, support them instead of hiring around them.

What are the warning signs when hiring?

A guaranteed outcome, a price quoted before any questions about your processes, certification presented as the entire qualification, no interest in involving your leadership team, vagueness about past work beyond reasonable confidentiality, and any push to buy software before the current process is understood.
