When to use it
Use it when you have an idea that's unusual or not fully worked out. “Worth testing” is honest about the uncertainty without putting the idea down. It frames the next step as an experiment, which is easier for people to say yes to than a big commitment.
Example
You: “Here's an idea worth testing: we send the renewal reminder a month earlier for one region.”
Manager: “Low risk. Let's try it.”
In an email or Slack message
In a brainstorm doc or Slack channel, label it clearly: “Idea worth testing: earlier renewal reminders. Small pilot, one region, four weeks.” A scoped test reads as thought through.
