Notes
Short writing from engagements—naming rules, path proof, cohort ghosts, and honest scope.
-
Freeze verbs before you rename widgets
UI labels change every sprint. Event verbs should not.
-
Path charts need device proof, not another meeting
A silent miss on one OS invents a cliff the product never caused.
-
KST midnight and the cohort ghosts it creates
Day boundaries move when warehouses stay on UTC and product calendars stay on KST.
-
What an instrumentation clinic actually covers
Expect clearer measurement decisions—not a managed analytics desk.
