A document in Spitfire is a defined set of specific, related information. And since there are many types of activities on a project, there are many different Doc types. Each Doc type is designed for a specific requirement. For example, a Meeting Minutes document allows you to enter Attendees, Agendas, and Meeting Items with Notes, and to schedule a new meeting, whereas a Change Order document has a very different structure to store information about your change order. But even though documents vary depending upon their Doc type, there are still some common elements shared by all documents.
