In this note, the author discusses how research shows that consistent growth companies engage in growth experiments or tests to gather better data to be used in determining which growth ideas are worth investing in. A Learning Launch is described as a process that can be used to do those growth experiments. Students will be shown that by doing Learning Launches, a business can evaluate many growth ideas quickly and cheaply, allowing it to gain better evidence to winnow down a multitude of ideas into a smaller group of ideas that appear to be more viable based on information learned.
