SYSTEM ANALYSIS AND DESIGN: ASSESSMENT-33Non-Functional requirements for Headspace ProjectFollowing are the non-functional requirements for the headspace project.Usability of the system: The developed system will provide ease of use for itsdifferent users such as physicians, patients and administrators at the health care facilities.Example of such usability incudes, the ease of navigation to the different web pages of theonline patient record system in four clicks or less than that. Reliability of the system: This is about the degree and level of the system uptimethat is required for the better performance and execution of the different operations dependenton the developed information system for the patients (Weaver et al., 2016). It is desired that,the developed online patient record system will have periodical redundant backups that willallow near about 99.5 percent uptime of the information system. Performance: This requirement is about how well the developed online patienthealth record system works for the different end users requirement in measurable parametersand degrees (Kho et al., 2015). This degrees includes response time of the system againstsome user service request, capacity and different other parameters.Scalability of the system: The system’s ability to respond and increase the number ofend users requests or interactions with the other applications used with the developed systemis known as the scalability of the system. For this proposed system it is desired that thesystem can be scaled to 50% of the present capacity (the number of users).Security: As the system will be responsible for storing the patient’s sensitive personaland physical health data thus it is desired to provide data integrity, confidentiality availabilityof the data round the clock while maintaining the compliance with the different legal clauseand regulations (Woods et al., 2013). It is expected that, the system will store the activity log

SYSTEM ANALYSIS AND DESIGN: ASSESSMENT-34all users’ access (doctors, users) at least for 6 months so that if anything goes wrong theaccountability of the accident can be confirmed. The developed online health record system must provide intense level of informationvalidation as well as error correction in real time (Weaver et al., 2016). The system mustconfirm that patient data is accessed by other users only after the patient has allowed accessto the user.The developed system must affirm and support (such as images, doc files, text files ordifferent other types medical documents and files) all the patient information entered in thesystem. End users (patients, therapeutic specialist and employees at the health care facilities)must be instructed and informed about any error regarding the different operations over theperiod of using the developed online patient health record system (Kho et al., 2015). Onlythe administrators or higher level system users are allowed to delete records in the database,and the structure should have the capacity to include new functionalities according therequirement of the users in future. Critical system qualities, interfaces, interface requirements, andsystem constraints Critical system qualities: For the On line health record system following are thecritical system qualities,The system can be integrated with different other existing applications that areused by the different health care facilities in the country (Weaver et al., 2016). System must be scalable as per the growing need of the physicians, patientsand health care facility. .
