Readings
These notes came in after Plot Room and the shorter surveys. We kept the ones that name a module, including the ones that complain. The house average across 91 written desk notes is 4.4; we do not display a widget that pretends otherwise.
The identity week assumed more warehouse access than our twelve-person shop had. I still finished Grid Instrumentation with a retention view our iOS lead would actually defend, after we borrowed the sandbox for two fortnights.

Stopped treating session_start as a business event. The dictionary week was dry. Dashboards got quieter, which is the point.
Platform note · 4/5 · Plot Room, March intake
Funnel Surveying made us strike three steps that existed only to look continuous. Conversion looked worse for a month. Finance stopped asking for a hockey stick we could not plot.

Niall here. Isolines finally explained why our D7 jumped every time marketing bought a Monday. Short course, long argument with the growth lead.

Identity Seams is the least glamorous thing I have paid for. It is also why our historic cohorts still mean something after the login rewrite. I would not send a junior alone; the reading list is dense.

Case notes
A twelve-person travel company had been celebrating activation at 61 percent. Grid Instrumentation’s first plate asked them to define activation as a behaviour a guest could fail. They chose “saved a trip with at least one paid night.” The number fell to 19 percent. The product lead was unhappy for a week and then rebuilt onboarding around the trip form instead of the splash animation.
Limitation they still live with: they cannot join web and iOS identity for guests who never log in, so the weekly plot reports the two surfaces separately. The house did not pretend a stitch was available.
Retention Isolines showed their “week” was a Monday–Sunday bucket while sellers actually returned on a fortnightly stock-up rhythm. Once the window moved to fourteen days aligned to first list, the curve stopped looking like a cliff and started looking like a ridge with a dip on bank holidays.
They still do not have a clean seller-to-buyer identity seam. Omar’s note from Cardiff would apply; they have not yet taken that survey.
