A way of running customer experience as an operating model, not a survey. Five pillars, in order, each one feeding the next. Not a model for workshops. The architecture a serious operator can deploy, measure, and compound.
Most programs collect signal, build a dashboard, and stop. The dashboard goes up on the wall, the board asks how it is moving, and it does not move. The reason is almost never the survey. It is that there is no operating model underneath it turning attention into action.
H.E.A.R.T. names the five things that model has to do, and the order it has to do them in. The order is the point.
The precise signal the business believes carries strategic information, and the discipline to capture it without flattening it into a single number. Hearing is not running a survey. It is knowing what you are listening for, and from whom.
Designing the journey the signal points to: the moments, the handoffs, the places the experience is made or lost. You cannot engineer a journey you have not heard, which is why this pillar comes second and never first.
The point where the design becomes the daily behaviour of the people who serve the customer. Most programs fail here, and they fail because they reached for activation before they did the hearing or the engineering underneath it.
What happens when the experience breaks, which it will. The closing of the loop is the part the customer actually feels, and it is almost always the part that is skipped. Resolution is where loyalty is recovered or quietly lost.
Measurement of behaviour, not sentiment. The pillar that tells you whether the other four are compounding or drifting, and feeds the next cycle of hearing. Tracking closes the loop on the model itself, not just the customer.
The framework is sequential for a reason. You cannot engineer a journey you have not heard. You cannot activate a journey that has not been designed. A program that starts at Activate, which most do, is building behaviour on top of a guess, and the guess is what the board eventually pays for.
Read the other way, the sequence is a diagnostic. When a CX program stalls, the failure is rarely where the symptom shows. A team that cannot activate usually skipped hear or engineer. The order tells you where to look.
This is the public account of the method. The longer argument lives in the cover essay, Customer obsession is an operating model, and the printable version of the first pillar lives in the five-question one-pager.
Time to Grow is where the thinking is written down and given away. When an operating team needs the method built into their company, that work is productised at Customera: a diagnostic first, then a system their own team runs after the engagement ends.
