Training Builds Potential.
Mentoring Builds Results.

Most Lean Six Sigma programs fail not from lack of training, but from lack of guidance when it matters. The right question at the right moment, the error caught before it compounds.

That's why VRI's certification programs have always combined rigorous training with hands-on project mentoring. We don't just teach the tools. We guide professionals through real projects to deliver real outcomes.

It's how we've documented $4.4 billion in client value.
