Dogfooding
Dogfooding is when a company uses its own products or services. I remember this term originating from Microsoft, although Wikipedia has some evidence linking it to actual dog food.
This has many benefits, including finding a variety of bugs. It isn’t a complete solution, as it doesn’t address extreme edge cases. It also doesn’t match the scale of coverage that would come from a public product rollout.
If you’re not in software development, it is a strange phrase. Another one I learned a few years ago is a “bug bash”: a dedicated event to test software as a team, looking for bugs. Like concentrated dogfooding.
If you’re gathering feedback on features, is that a feature gala?
