Abstract: Systems, displays, and methods for recording and tracking protocols being followed by businesses or individuals in particular real-world scenarios. The system enables users to generate and share customized decision tree displays and files indicating decisions involved in real-world scenarios. The system allows users to support or defend particular decisions by inputting customized/specific information and associating the user-input information with specific decision nodes in a decision tree. The user-input information can be saved in a decision tree file and displayed in conjunction with the decision tree in such a way that the user-generated association is conveyed to any viewer of the decision tree. Users can be enabled to upload supporting documents, select supporting regulatory/authoritative citations, add commentary, post hyperlinks, indicate that independent or additional approval/review was given, and the like.
