This document discusses genres and how they can be analyzed to improve information flow in organizations. It defines genres as "typified rhetorical responses to recurring social situations" that act as "tools-in-use." Genres can be examined based on their development over time and how they function at different levels of activity (macro, meso, micro). Analyzing how genres relate to each other through genre ecologies can also provide insights. The document provides examples and exercises for applying genre analysis in work contexts like social media to better understand information flow challenges.
