The FAANG companies, particularly Google, have a unique approach to engineering design sessions where engineers focus on solving complex problems without considering typical requirements that smaller companies or open source software face. This allows for a sophisticated foundation to solve problems but can lead to solutions that are too vague and confusing for users. The authors of Authzed, inspired by the Zanzibar permission system at Google, have built a product with an intuitive end-user experience in mind, updating their terminology to make it more approachable for non-engineers, signifying maturity in their development.
