The document discusses three different implementations of DITA (Darwin Information Typing Architecture) across different verticals: a technical implementation at Xerox, an implementation for human resources documentation, and an implementation for learning and training materials. Each implementation faced different challenges related to authoring tools, content management systems, and output types, but was able to leverage common DITA concepts and processes to dynamically deliver standardized, reusable content more efficiently across channels. DITA allows organizations to implement structured content management successfully in various domains beyond just technical publications.
