2SYSTEM ANALYSISIntroductionTelehealth project is introduced for enhancing the quality of health services in rural areasand the public hospitals of the rural regions by overcoming the challenge of long distance.Telehealth can provide convenient, cost-effective and real-time healthcare services. Telehealthproject aims to enhance the patient outcomes (Steele & Lo, 2013). Cloud based solutions willprovide on-demand services and resources over the Internet in a cost-effective manner. Thisreport discusses the non-functional requirements of Telehealth, strengths and weaknesses ofcloud based solutions. It also suggests an SDLC approach for the project after discussing the prosand cons of predictive and adaptive SDLC approach. 1. Non-Functional Requirements of the SystemNon-functional requirements can be considered to be the main qualities that need to bepossessed by the system. It also specifies the constraints of the system. Non-functionalrequirements of a system focus on the system behaviour and how it works (Ameller et al., 2012).The Telehealth project has certain non-functional requirements that are discussed below. 1.1 FunctionalityFunctionality is one of the main requirements of the Telehealth project that identifies userneeds and preferences. Telehealth should be able to improve the healthcare quality in the ruralregions by providing high quality health services with the help of the cloud platform. It shouldovercome the issues that are faced by healthcare professionals as well as consumers such as time,cost and long distance via remote patient monitoring over the cloud platform. Telehealth projectshould create links among urgent health care centres in the rural areas with emergency

Flexibility and robustness are alsoincluded in the functionalities of Telehealth.1.2 UsabilityUsability can be considered to another main non-functional requirement of the Telehealthproject. It can be considered to be the ease with which the healthcare professionals and thepatients will be able to learn about the cloud based system of Telehealth and operate it.Accessibility, consistency and interface aesthetics are the main usability requirements of theTelehealth project. Telehealth cloud platform should be able to eliminate the communication gapthat exists in the healthcare services by developing user-friendly and interactive cloud basedportals that can be used by the patients and healthcare professionals in an effective manner(Chung et al., 2012). Telehealth project should eliminate the problem of distance via videoconferencing and cloud platforms. 1.3 ReliabilityReliability of Telehealth will depend on its recoverability, accuracy and availability.Reliability is one of the most important non-functional requirements because Telehealth will dealwith the lives of the patients. Telehealth cloud based system should have less possibility offailure, low downtime and should quickly recover in case of a failure. The Telehealth systemshould produce consistent result and improve the healthcare services via video conferencing andmobile patient monitoring. Telehealth system should be able to quickly recover health relateddata from the cloud storage during any emergency and should backup data on a regular basis.
