I’m Rex Tuozo, Master Black Belt of Six Sigma PH, with over two decades leading improvement work in the service industry. Across our client projects, teams have delivered over ₱2.5B in combined cost savings and additional revenue.

My approach is intentionally anti paper belt. The goal in Six Sigma is not to earn a certification. The goal is to earn trust through results.

Trust is what unlocks promotion, influence, and better opportunities at work. When leaders trust you, you get assigned higher-impact problems, you get faster decisions and support, and your work becomes visible and credited to you. That trust compounds into bigger projects, stronger sponsorship, and accelerated career growth.

The research-based Trusted Improvement Leader Readiness Scorecard reflects this philosophy. It helps you assess whether your current experience and behaviors are strong enough to be trusted and relied upon to lead improvement that actually gets implemented and delivers measurable impact.

Customer testimonials

Here’s what our clients are saying about this Trusted Improvement Leader assessment:

This scorecard helped me slow down and assess myself honestly. Instead of rushing into the next belt, I now have clarity on my readiness and the path that makes sense for my career. It reinforced Six Sigma PH’s focus on real impact, not paper belts.

Francine Lopez

This felt less like a quiz and more like a professional checkpoint. It helped me see how ready I really was to lead improvement work, not just understand the tools. The results clarified where I already had credibility and where I needed to strengthen alignment and visibility before taking on bigger Six Sigma roles.

John Bryan Cruz

The assessment was eye-opening. I thought readiness for Six Sigma was mostly about tools, but the TIL Scorecard showed me gaps in facilitation authority and credibility transfer that I hadn’t considered. It helped me understand what kind of leader I am today, and what I need to build before stepping into higher-impact projects.
