The paper "Virtual Home System Design " is a perfect example of a business case study. Provide a simplified interface for entry of data. The system should provide a good interface that can be operated easily by both the aged and the home-visiting care staff (HVCS). The elderly patients should access the system and enter their personal information and the home-visiting care staff (HVCS) on the other hand should be able to enter the progress of each of the patients. This includes the daily records of the elderly patients attended and the overall time of their service delivery. All the information needed should be entered first before the approval of the information. Since the system shall be used by different people, each and every user should have enough or the required information first before working on it.
The elderly patients are given enough time and space to enter their personal information, which includes the nature of their conditions. The home-visiting care staff (HVCS) shall only start attending to the patients once they have provided enough information. The system should contain or manage the information provided.
Generally, the system shall handle important information, which can in one way or the other be of help to other authorities in case the need arises. These authorities may include hospitals, the police or audit firms. The system should, therefore, store the various information in their respective places for accessibility. Information should be secured. Private information about the conditions of the patients is considered private and should not be accessible to anyone without their knowledge or a go-ahead to do so. The system should, therefore, protect the information stored in the system from malicious individuals who could in any way manipulate this information. NON-FUNCTIONAL REQUIREMENTS Performance of the system.
This entails the speed of the system. How fast the system can deliver the services it is required of it. In order to check on the performance of the system, we consider factors such as; Response Time, Workload, Scalability and Platform. For Ningbo Virtual Elder Care Service system, it should be able to quickly process information concerning the conditions of the elderly patients, send the information to the central command and send it home-visiting care staff (HVCS).
The time taken by the home-visiting care staff (HVCS) to respond when called upon for duty should also be minimal. Maintainability of the system. Since the system is required to process the data provided then send it to a respective destination, may it be the elderly patients, home-visiting care staff (HVCS), or the central command, it is prone to damage or wearing out. The system to be created should have the ability to be maintained in case it is damaged when processing the data. A system that can be maintained is more appropriate since it saves on the cost of building another system.
The system should also be able to carry out frequent checks that will detect any faults in the system and hence take the required actions to maintain the system (Peter, 2013). Scalability. Scalability is determined by checking how the system functions while the workload increases. The system should be able to adjust itself automatically, to perform more services and grow significantly when the workload increases (Peter, 2013).
