Cohort Instrumentation
Taxonomy hearings, identity contracts, and a graded readout. This is the programme with a full public outline, an instructor page, and a limitation we will not soften.
Courses
Four rooms. One public syllabus.
Only Cohort Instrumentation is documented page by page. The others are scheduled when a small group asks; write to the desk if a title fits the work you are already doing.
Retention Cartography
How to draw the map of who stays without stretching the window. Students bring one live retention table; we annotate the population until the line can be quoted in a board pack.
Funnel Forensics
A method for interrogating drop-offs that look like UX failures and are often double counts, delayed identity merges, or events firing on error states.
North Star Studio
Choosing a single App Analytics question the company will fund for a year, then writing the supporting events so the question cannot silently expand.
A fifth pattern, taught inside the flagship
Experiment readouts appear as a module in Cohort Instrumentation rather than as their own ticket. We found that isolated “A/B literacy” rooms produced prettier slides and the same unexamined windows. If you only need that module, say so when you write; we may point you to Field Notes instead of a seat.
