What counts as a source?
Something you can reopen: calls, support tickets, a named report, or a dataset. "Everyone is saying" is not a source.
Plan four weeks of trend research around leading indicators rather than headline noise.
Illustration: signal, clinics asking whether reminders can live in the booking tool; source, the last ten sales calls; review date, the first Monday next month. The trend research plan records that. It does not say the category is growing.
Something you can reopen: calls, support tickets, a named report, or a dataset. "Everyone is saying" is not a source.
Pick a date when new evidence could exist. A weekly review of the same five anecdotes will not make the trend more true.
Publish the observation and the source. Do not publish a growth rate you did not measure.
