# Amazon ADR process Article: ## Notes - Amazon implements ADRs without AAF in a strictier setup. - Anyone can start an ADR. - ADR can have several authors, who maintain and communicate the ADR content. They are called "owners". - Everyone can contribute to the ADR. All changes must be approved by the owner. - ADR goes through a review with a team. During review, the ADR can be accepted, rejected, or get new work assigned. - ADR requires at least one approval to get accepted. - Once accepted or rejected, ADR is immutable. All changes require a new ADR. - Project owner seems to have a deciding voice in the process. ## Conclusion Amazon implements ADR in a more bureaucratic way. Instead of seeking advice, the author seeks an approval. The ADR is reviewed by the team, instead of a cross-functional group of stakeholders.
