2HUMAN FACTORS IN SYSTEM DESIGN
Introduction
Design and development of interactive system is considered to a vital aspect of
everyone’s life. Usability engineering is a method which is used for understanding the progress
of both software and system. It is mainly inclusive of user contribution which is needed for
inception of the given progress. Along with this it mainly aims in increasing the effectiveness of
the given product by the help of usability metrics and its requirements. Usability comes up with
three components that is effectiveness, satisfaction and lastly efficiency. Previously the
interactive system was nothing but command lines which are controlled in tight way for
interaction between human and computers. User need to have an idea regarding the commands
which might have any kind of issues and how different arguments can be ordered.
The coming pages of the following report helps in getting an overview of interactive
system. After that an analysis of the given website that is CurryPC has been provided. A proper
idea of interactive system and its users has been provided in details. A methodology has been
provided with respect to usability of the given website. A proper definition has been provided
regarding the evaluation method for this website has been provided.
Interactive system Definition and its users
Interactive system can be easily stated as a system which provides proper interaction
between systems and human being. Let us considered the given example of graphical interactive
system in which an OS is installed in the given system (Preece, Rogers and Sharp, 2015). There
are large number of software application like data entry systems, simulating software and CAD
as it requires high level of interaction among users. IDEs and other kind of web browsers are
some best example of interactive system. Around 90 percent for the given effort which is needed

for proper technology mainly helps in improving the proper interaction of different users within
the provided system.

Proper preference of people and its features can be useful for attracting a number of
people which is needed for having a proper development of the provided system (Mast et al.
2015). It requires proper analysis regarding the needs of users along with the proper development
of the given interface along with alignment with proper interface of the system which is about to
be developed. Construction of unambiguous icons needs to be provided and common problems
which are there in usability of the given system (García-Peñalvo and Durán-Escudero 2017). It
provides a proper kind of command line between computers and other kinds users associated
with it. Previous available command lines are available between the line of interface between the

computer and its target users. The command line interface is widely used which needs sufficient
amount of knowledge regarding the commands or any kinds of arguments for desired outputs.
The provided data needs to be given to computers in proper way. The given data needs to be
given in the system in the proper way in the limited way. It comes up with certain number of
limitation for having certain number of outputs (Glas, Kanda and Ishiguro 2016). But Currently,
there are certain number of virtual system and other system like direct manipulation system and
embedded system which provides best kinds of interaction and is helpful in achieving maximum
benefits from the system.
Methodology of Usability Evaluation
Usability of the given system can be done by making use of different types of
methodology (Cooper et al. 2014). It helps in having idea which can be used for collecting
feedback with respect to the website that is Curry’s pc world. A large number of usability
evaluation of methodology can have applied are provided below:
Report of Usability Test: The output of the given usability can be achieved by proper
analyzing the recommendation and other kinds of finding which be differentiated with the
provided level of severity (Cheng et al. 2016). The gathered information is generally obtained by
the help of test planning which is sufficient for the given methodology.
Recruitment for test participation: Only those participations should be recruited who
are expected to have the idea of the website and there can some kind of potential groups and its
users. The participation of the users should be totally based on the given site and along with it
can have some of the multiple users (Abdelnour-Nocera et al. 2015). Each of the provided group

members should come with representative which is used for optimization of the given test
performance.
Test planning of Usability: It is the most important factor involved in design of test plan
which needs to build for proceeding with the given test.
Test at first click: The components of the given interface which is clicked by user for
completing the given task (Alavi et al. 2016). Progressing with the given test prototype of the
given website wireframe and its functionality needs to be checked.
Scale of System usability: It is well known tool which helps in checking the usability of
the given system. It comprises of 10 questions in the given questionnaires. Six responses are
taken from it which comes up with option which starts from agree to strongly agree.
Review of expert and evaluation in terms of heuristic: In this particular method it can
be easily review by different expert in comparison to the principles for acceptance usability
(Baecker, 2014). The ultimate result of this particular thing is its analysis regarding the different
kinds of problem in the provided system.
