The document discusses the concept of agile review, which was developed by applying agile methodologies used for software development to the review of technical documentation. The agile review approach focuses the review on the critical content that fulfills the purpose, rather than reviewing all document content. It is based on the premise that 80% of meaning is derived from 20% of content. The review concentrates on key elements like the argument structure, logic, usability, and quality of argument. This approach aims to make reviews more efficient and focused on the most important information.
