Evaluation of the Design
The report is prepared for analysis of the interface design and discussing on the
framework and content of the web interface. The current web interface is designed according to
the needs of the organization and it is kept simple such that the users accessing the website does
not face any problem while using the interface. The selection of the text, icon and the sub section
is the main criteria for the success of the web interface (Omerdic, Toal & Vukic, 2016). There
are different evaluation technique for testing the usability Neilsen & Molich heuristic approach is
applied for the evaluation of the user interface. The goals and objectives for the organization for
whom the interface is designed should be analyzed for identification of the problem in the
usability and improvement of the performance of the interface. The alternatives of the user
interface design should also be analyzed and the best design should be selected. An example of
good design is attached for evaluation of the interface design.

Neilsen & Molich heuristic approach for evaluation of the usability
Visibility of the system status
The system should be developed such that the users can get all the details of the business
and take feedback from the users for improving the features and functionality of the system.
Matching the real world and the system
The language used for interpretation should be kept simple and the phrases should be
familiar with the user. The real world convention is important for the natural and logical ordering
and making the website more appealing to the user (Nielsen, 2014).
User control and freedom
The emergency state should be handled by the system such that the user does not reach to
the unwanted state and appropriate error message should be displayed to the user in case of
wrong input.
Standards and Consistency
For designing the user interface good principles should be followed and appropriate
decision regarding the design must be selected such the alternatives of the interface can be
determined. Maintaining the standard during the development of the user interface caused less
number of errors.
Prevention of Error
The errors in the project can be mitigated with maintaining the standards and taking
precaution during the development of the user interface. A condition of error checking should be
applied and the errors should be mitigated for the committing the action.

Recognition of the features
The actions and the different options must be visible to the users such that the user does
not need to remember the functionality of the website (Bargas-Avila & Bruhlmann, 2016).
Proper labeling and buttons should be used such the action can be predicted by the user.
Flexibility and efficiency
The design must be kept simple and the experienced and the inexperienced users must be
involved in the usability testing for identification of the efficiency of the interface design.
Minimalist Design
The irrelevant information should be removed in order to keep the design simple and
increasing the visibility of the website.
Diagnosis and recovery of the errors
A solution of the problem or error found should be recommended to the development
such that the interface is aligned with the needs of the users.
Documentation and help
The designer is responsible to create an user documentation such that the functionality
are defined and it becomes easy for the development team to develop the whole website.
Identification of the issues and its problems
The main issues identified regarding the interface design is that the less information are
used for designing each of the pages and headings are not used. The lack of using the headings
causes the users to feel redirected and the same framework should be followed for all the user

interface (Kortschot et al., 2017). For the identification of the problem a survey and
questionnaires should be used for finding the requirement. The prototype of the user interface
must be shared with the users for modification and adding new functionality.
Remedies and action for resolving the issues
The problem with the current user interface design can be mitigated with the involvement
of the users in the development phase. The header and footer of the web interface should be kept
same such that the user does not feel they are redirected. Same font size and style should be
followed for the headings and labels for the improvement of the look and feel of the interface.
The use of relevant graphics content should be increased for making the user interface interactive
and attracting more number of users using the website. All the functionality demonstrated in the
user interface must work properly and error message must be displayed to the user if any wrong
input is provided by the user for maintaining the flexibility of the web interface design.
