The document discusses the roles of a business analyst in agile vs standard project management practices. In agile practices, business analysts work collaboratively with users to elicit requirements through observation and trial-and-error rather than lengthy documentation. They help create a shared understanding of product goals. Some of their roles include writing user stories, providing feedback, setting roadmaps, and ensuring the team stays on course to meet business needs. The document also notes challenges for business analysts in agile environments include producing requirements faster and at a different level of detail than traditional methods.
