Looking at the source, this appears to be a marketing research tool that helps you map out competitor alternatives systematically. You'd use this when positioning a product or preparing competitive analysis, and it likely prompts you to think through direct competitors, adjacent solutions, and the "do nothing" option that customers might choose. The honest take is that it's probably most valuable for forcing structured thinking rather than finding competitors you didn't know existed. Good for product marketing teams who need to document their competitive landscape or sales teams prepping for objection handling.
