Product Signal Mapping
Name events so they survive a rebrand, then draw journeys that do not collapse when a screen is renamed.
Ledsham desk · App Analytics atelier
The map is not the dashboard.
Most product teams drown in charts they cannot defend. Node Mapbase trains people to draw the actual terrain — events that mean something, journeys that weather a release, and readouts a sceptical director can follow without a legend taped to the wall.

“I arrived with twelve dashboards and left with four questions I could actually instrument. The taxonomy week dragged — we are a two-person studio — yet the dictionary is still pinned above our stand-up board.”Priya M., product lead, Leeds
On the table this season
Three programmes, one discipline
Retention Weather
Treat retention as climate, not a single percentage. Read the fronts that move after an onboarding rewrite.
Funnel Forensics
Interrogate a leaking funnel without blaming design first. Find dropped properties, ghost steps, and silent errors.

How the atelier works
We teach with a red pen, not a template pack.
Each week you submit a map: an event dictionary, a journey overlay, or a readout. A tutor marks it as if it were going to a sceptical board in Manchester or Edinburgh — the praise is specific, the cuts are too.
You will not receive a secret warehouse schema. You will receive the habits that keep App Analytics honest when the next product manager renames “Checkout” to “Complete bag”.

Field notes, not recaps
An invitation
Bring a messy app. Leave with a map you can defend.
Fees are listed without checkout on this site. If a programme looks right, write to the desk and we will tell you the next cohort date.
