Design evaluation
The evaluation of the design is done for the completion of the Assessment Item 3, according to
the evaluation the Heuristic Principles given by Neilson Jackob are used to evaluate the provided
design of the other team members. The design was evaluated for the 10 specified principles of
the Heuristic design and evaluation approach and the recommendation for the improvements
were provided (Hasan, 2013). This work was done by team members: Pradeep Reddy Bhavanam,
Jeevan Reddy Abbadi, and Vasudeva Reddy Kakireddy.
Design Usability Evaluation Principle
Evaluation by Pradeep Reddy Bhavanam
1. Visibility of system status
Location of issue: the location of the issue is on the ticket details page of the design (figure 1).
Reason of issue being a problem: the system does not display the seat number to the user which
is a problem causing the situation.
Issue (minor/significant): Significant issue
2. Match between system and the real world:
Location of issue: the location of the issue is on the booking confirmation page of the design
(figure 2).
Reason of issue being a problem: at the bottom of the page, there is a blue box symbol
multiplied by 2, which confusing for a naïve user to understand.
Issue (minor/significant): Minor
3. User control and Freedom:
Location of issue: the location of the issue is on the parking page of the design (figure 3).
Reason of issue being a problem: the back button on the page does not redirect the user to any
page and there is no option for logout.
Issue (minor/significant): Significant

Evaluation by Jeevan Reddy Abbadi
4. Consistency and Standards:
Location of issue: the location of the issue is on the parking confirmation page of the design
(figure 4).
Reason of issue being a problem: the back button generally meant for the redirection to the
previous page, in this page the back button does not work at all.
Issue (minor/significant): Significant
5. Error prevention:
Location of issue: the location of the issue is on the change password page of the design (figure
5).
Reason of issue being a problem: the password change page is not linked to any page and also
the page accepts all type of password.
Issue (minor/significant): Significant
6. Help users recognize, diagnose and recover from error:
Location of issue: the location of the issue is on the seat selection page of the design (figure 6).
Reason of issue being a problem: the issue does not ask the user for confirmation before going
for the payment page.
Issue (minor/significant): Significant
Evaluation by Vasudeva Reddy Kakireddy
7. Aesthetic and minimalist design:
Location of issue: the location of the issue is on the movie page of the design (figure 7).
Reason of issue being a problem: the information of the movie is displayed along with the
name of the movie which is the display of irrelevant information.
Issue (minor/significant): Minor
8. Flexibility and efficiency of use:
Location of issue: the location of the issue is on the OTP page of the design (figure 8).

Reason of issue being a problem: the problem is that the user is not allowed to go back to the
login page.
Issue (minor/significant): Significant
9. Recognition rather than recall:
Location of issue: the location of the issue is on the find ticket page of the design (figure 9).
Reason of issue being a problem: the reason of this being an issue is that the user has to enter
all the detail fields then only the user is able to find his ticket.
Issue (minor/significant): Significant
10. Help and documentation:
Location of issue: the location of the issue is on the seat selection page of the design (figure 10).
Reason of issue being a problem: the problem with the page is that it does not allows the user
to generate a receipt of the parking extension.
Issue (minor/significant): Minor

Recommendation for design improvement
Table 1: Design improvement recommendations
S. No. Principle name Screen name Recommendation
1. Visibility of
system status
Ticket details
page
The page should include the feature of
the seat number display or the user will
be confused for the seat and this will
create unnecessary chaos.
2. Match between
system and real
world
Booking
Confirmation
page
The blue box is used to define the
booked tickets which is a little
confusing, to improve that either
includes the label that shows what blue
box represents or use Booked tickets.
3. User control and
Freedom
Parking page The back button of the page should be
linked to the previous page of the home
button or collapse menu bar.
4. Consistency and
Standards
Parking
confirmation
page
The back button should be linked to
make use of the arrow symbol and
maintain consistency.
5. Error prevention Change password
page
The page should be linked to the
OTP/forgot password page and a link
of password content recommendation
should also be included.
6. Help users
recognize,
diagnose and
recover from the
error
Seat selection
page
The user should be asked for the
confirmation of the seats and for the
approval to move to the payment page
to avoid any mistake from the user
side.
7. Aesthetic and
minimalist design
Movie page Any detail related to the movie should
be displayed on the page relevant to

movie information. The presentation of
so much data along with movie names,
makes the page design to be
unattractive.
8. Flexibility and
efficiency of use
OTP page The user is not given the flexibility of
moving in/out of the system whenever
the user wants therefor an option of
login/logout should be there on OTP
page.
9. Recognition
rather than recall
Find ticket page The find ticket page should not ask the
user for so many details, it should just
show the tickets that are not scheduled
for the future (Yáñez, Cascado
Caballero, and Sevillano, 2014).
10. Help and
documentation
Car booking page The car booking page should be
renamed as parking booking page and
the page should allow generating a
receipt of the same booking.
Usability strategy
The design presented here is the provided design for the purpose of evaluation and this design is
not meeting the user requirements fully. The design needs to be improved for usability principle
implementation and the attractiveness also. The design does not contain any image and is not
attractive to the eyes. The main reason that leads a customer/user towards using an application or
website is the look of the same and this need to be enhanced.
There is a need for the team to implement various principles of designing usability on various
pages. The receipt generation option should be provided for both parking extension and ticket
booking. The option to login/log out of the system should be provided in the designs. Other
features like the empty footer and linking need to be enhanced in order to make the design look
more attractive and user-friendly (Hoehle, and Venkatesh, 2015).

Table 2: Design Strategy table
S. No. Start of designing strategy During design strategy End of design strategy
1. The system requirements
should be properly listed.
Look of the design should
be considered while
designing.
Requirements should be
cross-checked.
2. No of screens should be
decided.
The logical and required
screens should be added as
per need.
The screen should be
linked.
3. First focus on fulfilling the
requirements.
Designing principles must
be implemented during
designing.
Principle-based
evaluation.
