Hospital needs to find a way to improve voice over IP (VOIP) call tracking within the hospital and also wants to have a program to improve the response time of medical personnel by using GPS to locate the vehicle closest to the emergency. A design should be made based on the Requires and Provides interfaces of two components that could be used in the VOIP system. An interface design is required for two components that can be used in the vehicle discovery component to find the vehicle closest to the incident with the Requires and Provides interfaces. According to Sommerville (2011), interface Provides are services provided by the component. , where the Requires interface specifies which services are necessary for other system components to function properly (p. 457). The hospital wants to improve tracking of VOIP calls made within the hospital system. The emergency control room will have a call logging system that will record calls made. The first item would be phone call tracking. The Require interface can be the caller ID service that powers the component. With the caller ID service, the interface Provides will allow you to see the phone number to call, the phone number from which it is calling, the time of the call, the duration of the call and a log file to see all calls made from a phone. or all phones. To track calls, management will wait to see the phone numbers of internal calls coming from and to. Management will also want to see the time of the call and its duration. If management believes that employees are spending too much time talking on the phone and doing it more often than necessary, management can keep a log of these two...... middle of paper ...... to find the appropriate vehicle that is closest to the emergency. The vehicle number will be recorded and informed of the emergency. In addition to the patient information and expected incident sent to the vehicle, the GPS will provide directions from the current location to the patient and the quickest route back to the hospital. The GPS will give hospital staff an idea of ​​how long it will take the vehicle to get to the hospital and have the equipment, room and staff ready to help the patient. By taking the quickest route and having medical personnel ready to receive the patient, it could mean the difference between life and death depending on the incident.
