Teach with examples — not hand-written rules for every case
This page walks a complete decision. Priya Nair places customer churn inside the standing case (build a photo sorter for plant health without pretending the model understands gardens) at Riverside Garden Club, with trade-offs visible. Use a decision table for customer churn: mechanism, evidence on hand, public language, owner, monitoring. Fill it with colleagues at Riverside Garden Club, not alone; park disagreements instead of forcing false consensus.
During a real interruption at Riverside Garden Club, Priya Nair stress-tests “Parallel: churn models and plant risk scores” on customer churn: one queued question, one hurried call, one hallway challenge. If the idea only works in a quiet workshop, it will not survive the standing case (build a photo sorter for plant health without pretending the model understands gardens).

Deployment with a human confirm step
Bring spam examples onto Priya Nair’s table as a boundary object—something that clarifies what Riverside Garden Club will not claim while deciding the standing case (build a photo sorter for plant health without pretending the model understands gardens). A strong worked scenario rejects at least one tempting label or automation around customer churn and keeps at least one careful use. Rejection is part of competence.
Count something crude about customer churn—misses last week, minutes lost, or people affected—and write the number beside spam examples. Priya Nair needs that comparison before anyone at Riverside Garden Club declares victory on the standing case (build a photo sorter for plant health without pretending the model understands gardens).

Communicating uncertainty on the club app
Define human review for customer churn with teeth: time, knowledge, access to evidence, and authority to disagree at Riverside Garden Club. Decorative approval after customer churn already shipped does not count—especially when spam examples shows how late review fails. Write the review step before irreversible action on the standing case (build a photo sorter for plant health without pretending the model understands gardens).
On “Communicating uncertainty on the club app”, Priya Nair edits language about customer churn the way an editor would: strike “sentient,” “infallible,” and “just a tool” wherever they hide responsibility inside Riverside Garden Club. spam examples stays nearby as a plain-language control.

Retrospective after the first blight weekend
End with a reopen criterion—an observation in the next weeks that would revise the decision about customer churn for the standing case (build a photo sorter for plant health without pretending the model understands gardens). Decisions without reopen criteria become folklore at Riverside Garden Club; Priya Nair writes the criterion next to the spam examples boundary note.
For “Retrospective after the first blight weekend”, a second person at Riverside Garden Club challenges Priya Nair’s note on customer churn and asks whether spam examples already solves most of the need with less mystery. That challenge is part of finishing the standing case (build a photo sorter for plant health without pretending the model understands gardens), not a delay tactic.

Why this matters
