Signal inventory
List every event that could enter the score. Strike anything that only flatters the roadmap. Guest chairs from a Bangkok super-app share one inventory they later regretted.

Resonance Ledger
An Engagement Score Analytics studio for people who must design, weight, and defend a composite score in front of colleagues who do not live in SQL.
Who it is for
Product managers, lifecycle leads, and analysts who already ship some kind of engagement number and can feel it wobble. You should be comfortable reading a query result, even if you do not write production SQL. You do not need a statistics degree.
If your company only allows Mixpanel’s or Amplitude’s built-in engagement score and will not export events, much of the weighting work will stay conceptual. We say that before you pay, not after week four.
What you leave with
- A written definition of engagement for your product, signed off by you — not by us.
- A signal inventory with struck items and reasons.
- A weighting memo that a non-analyst can retell.
- Three scorebands with owners and stop conditions.
- A six-month drift-watch calendar.
Modules
Eleven weeks, eight named rooms
Weighting without folklore
Replace “this feels important” with documented weights. You will defend why recency is not automatically king, especially around Thai festival calendars.
Recency, frequency, and the quiet middle
Work the users who neither churn loudly nor light up the dashboard. Most composite scores punish this group by accident.
Scorebands and intervention thresholds
Design bands that a lifecycle team can operate. Each band needs an owner, a trigger, and a condition that stops the machine.
Cohort drift and recalibration
Practice a monthly check. You will simulate a silent feature launch and watch last quarter’s “highly engaged” definition expire.
Presenting scores to non-analysts
Six-sentence defence, no slide theme. Country managers and finance partners sit in on one rehearsal.
Governance, bias, and audit trails
Who may change a weight? What gets logged? How do you notice when a score quietly disadvantages a region or a language?
Studio critique of a live model
You present. Two visiting chairs and faculty try to break the logic. The week after, we run the optional drift-watch return.
Faculty
Arunwadee Srisuk
Principal tutor. Former lifecycle lead at a Bangkok super-app, where she inherited an engagement score that mixed payment recency with push opens and called the blend “loyalty.” She spent two years taking that number apart. At Vault Routecore she runs Resonance Ledger and the monthly alumni evening.
Office hours in Thai and English. She does not grade dashboards; she grades whether your definition survived a user story.
Fee (informational)
THB 48,500 per chair for the 2026 season, exclusive of VAT where applicable. Includes critique day, the drift-watch invitation, and alumni evening access. Does not include travel, hotel, data-platform licences, or internal analyst time. There is no checkout here — see seat memos and refunds.
Twelve chairs. When the room is full we open a wait list for the next Bangkok cycle.
From chairs who sat it
Week three forced us to drop push opens from the wallet score. I argued for keeping them. I lost, correctly. The critique day still felt abrupt — two visiting chairs and very little small talk.
★★★★☆
Clearer than any internal workshop we ran. Warehouse access was on us; they warned us. Would not enrol a junior without a senior sitting alongside.
Questions we actually get
Will this replace our data engineering work?
No. Resonance Ledger does not teach you to rebuild a pipeline, choose a warehouse, or implement streaming. You still need warehouse access — or the sample dataset — and a product owner who will live with the definition. If your engineering queue is frozen, the artefacts will be conceptual. That is a real limitation of the course, not a footnote.
Is it taught only in Bangkok?
Live sessions run from the Nongkhaem desk and online in the same cohort. Critique day can be attended remotely. House Vault teams sometimes host a half-day on-site in Bangkok; that is priced separately.
Do you certify a vendor tool?
We do not. If your company only uses a platform’s default engagement score, we will still teach weighting and bands, but you may not be able to implement every exercise inside that UI.
What language is used in class?
English for lectures and critique. Thai-language office hours with Arunwadee are available every other week.
