2ITC 548 SYSTEM ANALYSIS
Introduction
The NewAccess project is associated with the development of an information system that
aims in secure storage of the health information of the patients with mental health issues. The
proposed project aims in storing data of patients in order to reduce the issues faced by those
patients while retelling their story. The funding for development of this information system is
already proposed therefore the viability of making use cloud storage and solution for the system
will be judged (King et al., 2014). The report will be evaluating the nonfunctional requirements
of system proposed. The appropriate cloud based solution that can help in effective
implementation of the project will be discussed in this report. The system’s non-functional
requirements will be evaluated on basis of FURPS+ acronym to ensure that the functionalities
that are being proposed for the system implicates the usability, reliability, performance and the
security of a system. The report will evaluate the cloud system that will be useful for this
particular system (Meeks et al., 2014). The report reviews the cloud approaches and the SDLC
models that can be used in development of this NewAccess information system.
1. Non Functional Requirements
The non-functional requirement that is to be identified for the NewAccess system is
based on usability, reliability, performance and the security needs of a system. It is quite
essential to identify the systems’ nonfunctional specifications as it helps in identification of the
system’s operation. The system’s non-functional requirement provides an idea of attributes that
the proposed system will involve. The identified requirements of the proposed system provides
an idea of the main attributes of the system. The FURPS represents the model of classifying a
software on basis of the quality attributes.

1.1. Functionality
The functionality of the proposed project represents the vital feature of the system that is
mainly familiar with the business domain of the solution that is being developed. The
functionality of the system is mainly technical oriented. The main nonfunctional requirement of
the proposed system based on its functionality includes improved performance. The proposed
system should be able to provide a high performance of speedy data processing and very less
response time.
1.2. Usability
The usability feature of a system incorporates is one vital nonfunctional requirement of a
project. Since the project will be used both by the doctors and the patients, it is essential to
develop a system having effective usability. The requirement of usability of the proposed project
includes development of a system that will ensure effective report generation that will in turn
improve the usability of the system. Therefore, continuous report generation of the medical
health of patients is an important nonfunctional requirement of the proposed system.
1.3. Reliability
Reliability is associated with one of the most significant nonfunctional requirement
particularly because this system deals with storing data of the patients. The system that is being
developed should be reliable as it is related with the management and data storage of the
healthcare patients. The system’s reliability can be enhanced by making use of encryption to
increase the data security.
1.4. Performance
