TIT- Diagrams: Risk tree, decision table, use case and DFD 1- (1.5 pts) Risk tree: (7 minutes) A risk tree is supposed to help us identify risk causes. Identify a safety hazard as potential failure in the following simplified version of a patient monitoring system. Build a fault tree showing how this failure can be caused from basic events. You need to show all possible cases. Each patient in the emergency service of Wonderland City Hospital is monitored by an analog device that measures factors such as pulse, temperature, blood pressure and skin resistance. The software monitors these factors on a periodic basis, customized to each patient, and keeps them in a database for patient history tracking. For each patient, safe ranges are specified for each factor. If a factor falls outside of a patient's safe range, the nurse's station is notified. 2- (1.5 pts) Decision table (7 minutes) Create a decision table for a login screen. Email Password Log in
