Why I started this

20+ years learning this at large companies. Now I bring it to the shops that need it most.

Over 20 years in operational excellence and transformation, across manufacturing, aerospace, automotive, technology, banking and energy, in North America, Europe and Africa, I learned what actually makes continuous improvement stick, and what makes it fail.

Large companies can afford a team of consultants and a six-figure software budget to build this. Small manufacturers can’t, and most of what’s sold to them is either too generic to use or too expensive to justify.

TRI Principles Institute exists to close that gap: the same operating system, management system and people practices that work at scale, built directly in the tools you already have, at a price a small shop can actually afford.

How we work

Built on 3 principles

Performance improves when you design how work flows, manage it by example, and build the trust that makes people want to improve it.

OPERATING SYSTEM MANAGEMENT SYSTEM PEOPLE & MINDSET

01 · Operating System

Design how work flows

Standard work, visual boards and a way to flag problems at the source, so you can see at a glance when something’s off.

02 · Management System

Lead by example

Management holds itself to the same standards it asks from the floor, and shows up as much in good weeks as in bad ones.

03 · People & Mindset

Build trust and involvement

People raise problems without fear of blame, and get credit for the ideas they bring, so they own the improvement, not just follow it.

Why work with us

Made for shops without a software budget
