The Tertiary Method™

A way of designing experiences backward from the change that actually matters. Any designed experience operates on three layers. We design for the tertiary, what visitors carry forward, from the first conversation. The full method is set out in The Tertiary Effect, forthcoming late 2026.

Yes, though not with exit surveys and dwell time, and not with the same assurance as calculating if a beam can carry a load. Transformation is private, often delayed, and it resists the instruments institutions usually run on. Signal-based measurement, paired with machine learning trained on the language of transformation, turns faint and scattered signals into something you can act on. Without surveilling anyone.

No. The method scales because it's a way of making decisions, not a line item. Naming the change an experience is meant to make more likely sharpens a small project as much as a large one. Some of the most effective moves it produces cost nothing to build.

Neither position survives contact with a real project. Used well, AI and machine learning are additive: more ways for different people to find meaning in the same environment, less staff time lost to the tedious, more capacity to adapt when the day does not go as drawn. Technology should empower the people inside the experience, not extract from them. Where it widens discovery and dignity, we design with it. Where it manufactures emotion or surveils, we design around it.

Visitors should be recognized by an experience without being identified or tracked by it. That is recognition without identification: session bounded data, aggregate sensing, no covert biometrics. It's a design position rather than a compliance posture, and it produces better experiences, because a visitor who trusts the room opens to it.

No. We're hardware and software agnostic on purpose. We specify and recommend based on the project, not on partnerships, and we don't take referral fees.

That is a service we offer. We evaluate whether the technology belongs in the experience, how it might be applied, and what guardrails keep it responsible. Ask what it makes possible for the visitor that wasn't possible before, what it takes from them, and who it's really for. If the pitch answers the first question with a feature list, the second with silence, and the third with "marketing," you already have a signal. We can run the full evaluation with you.

Living documentation that connects systems to creative intent is already part of how we deliver. In development: the Experience Operations Platform, a knowledge system for operators when something fails, and the Experience Performance Platform, an inspector for experience quality against creative intent.
