3 SYSTEM ANALYSIS AND DESIGN1. IntroductionCloud computing is gaining importance with the passage of time. It can be considered tobe an IT model or paradigm that facilitates the users to access shared resources by using theInternet. Cloud based solutions include resources, applications as well as services to thecustomers and users on the basis of their demand via Internet. Headspace organization managesyoung patients who are suffering from mental illness like depression. Their aim is to develop ahealth record system by using cloud based platform services. This system will be able to recordpatient’s story when they are narrating it for the first time (Steele, Min & Lo, 2012). This report gives brief overview of the non functional requirements of the system. Itdepicts a comparison between the non functional and functional requirements of the healthrecord system. This report discusses about the pros and cons of a cloud based solution. It talksabout the strengths and weaknesses of the Adaptive and Predictive approach of SDLC. At theend it gives recommendation about selecting either the predictive or the adaptive approach.2. Non Functional RequirementsNon functional requirements of a system are the specific attributes that helps inunderstanding about the operations and quality of the system as a whole. It is not possible toevaluate these attributes prior to its delivery to the clients (Chung, Nixon & Mylopoulos, 2012).The working ability of the system can be evaluated by understanding these attributes. Some ofthe non functional requirements are reliability, security and functionality. The non functionalrequirements of the Headspace project are discussed below.2.1 Functionality
