While users can search in the Player to locate topics, it is recommended that an outline has a logical flow. This could mean an outline for training, with the topics grouped in a hierarchy of modules and sections that build on previous modules and sections, or an outline for reference, with the topics grouped in modules or sections that contain all the topics that have to do with a specific subject. You could also build an outline in which each topic in a section is a different task in a particular business process.
