SYSTEM ANALYSIS PG 3
Introduction
In general, the healthcare industry has rapidly moved towards the digital platform over the past
few years due to the amount of data it collects. In most cases, this data stems from patient’s
records which include extended descriptions of the diagnostics and treatment procedures. Now,
most of this data must be analyzed to yield conclusive results which necessitate the need for
cloud storage facilities which collect, process and distribute meaningful information. Moreover,
the same facilities enable the healthcare institutions to store their extensive records which are
then readily accessed from any location and using any digital platform. Similarly, the Headspace
project aims to promote the functionalities cloud computing into its existing IT infrastructure by
linking its proposed information system to a cloud service provider (Reddy & Reddy, 2013).
This report analyses the different system design parameters that will facilitate this collaboration
including the non-functional requirements of the system itself. Moreover, the attributes of cloud
solutions are given and so are the development methods.
The non-functional requirements
These are attributes or characteristics and that define the system design thus constrain it from
different functionalities across a wide range of operating platforms. Now, this definition is
different as compared to that of functional requirements which outline the functionalities and
operations of the system (Hassan, 2010). Therefore, these requirements define the system’s
interaction with the end user which promotes the usability outcomes.
System qualities
These elements facilitate and maintain the efficiency of the system thus ensuring that the overall
user structure is satisfied. Furthermore, if they are not met, the system may fail to meet certain

regulatory measures or standards set by the governing authority (Losavio & Chirinos, 2003).
Now, they are:
Performance – the overall utilization of the system which is measured using the response time,
static volumetric and throughput among many other factors.
Reliability and recoverability – consistency in operations and functionalities despite the changes
in operation platform or occurrence of hardships.
Security – the property, more so the data must be protected against illegal access or exposure.
Usability – the most critical component that determines the overall system’s satisfaction levels. It
is the system’s ability to facilitate operations through different practical functionalities
(Microsoft, 2017).
System interface and user interface (UI)
These elements represent the overall structure that interacts with the end user i.e. the outline that
delivers the results and allows users to give the system input. Its design generally dictates the
system’s performance as the user’s appeal will determine its usability. Therefore, the developer
must balance the technical prowess of the background structures with the overall system
interface i.e. items such as colour, icons and images (E-cartouche, 2017). To this end, the
following attributes are necessary:
Maintainability – the interface should live up to the time through update features i.e. patches that
constantly engage the users.
Interoperability – especially with all platforms i.e. operating systems and deployment languages.
