DOGFOODING
Практики использования компанией или командой разработчиков собственных сервисов и продуктов.

In startup culture, to “eat your own dog food” is to use your own product or service internally as a way to validate its quality and capabilities. In 1988, Microsoft manager Paul Maritz titled an office email «Eating our own dog food,» by which he challenged the recipients to increase internal usage of the company’s product. From there, use of the term spread through the company like
wildfire and was eventually taken up throughout Silicon Valley. The idea is that if you expect your customers to use your products and services, you should expect no less from your own employees.
Dogfooding as a verb also has come to mean the same thing.
