Question 1 Identifying and understanding the users
Part 1
a. Identified the users of the Pizza online system
The online system will be having various users and they will be the main system stakeholders
who include the following:
i. System administrator.
ii. Customers.
iii. Delivery staffs.
iv. Front office delivery person.
v. Database designers.
vi. System analysis.
vii. System developers.
viii. Webhost vendors.
ix. Accountants.
b. The required cultural aspects of the Pizza online website
While designing the pizza online website the culture is one of the main factor to be considered
since the culture determines the amount of the sale of some pizza products , this is determined by
the below cultural aspects.
i. Eating Habits.
The communities have different habits related to eating where some have possibilities of eating
some food or taking drinks at specific day of the week or the year while others take the pizza
meal at any given time.
ii. Eating Attitude.
The attitude towards some pizza feeds also affect the amount of food ordered as some believe
some pizza have no befit to their bodies while others have much faith on particular feeds.
iii. Community Believes.

5PIZZA SHOP OWNER DATABASE DESIGN
Some communities believe also affects the amount of pizza meal bought as some believe that
some pizza likes made from pork or fish are not clean for human consumption and therefore
selection of the pizza to be displayed in the website must be considered.
c. The required cultural aspects of the Pizza online website for a different country
In this case I choose Iraq as my new country in to which a new pizza shop can be opened and in
this country an online pizza website design should be different from the others due to different
culture that exist in that country which includes the following.
i. Eating patterns
In most of the communities in this country they have a pattern on how they eat where some eat
thrice, four times while other take two meals in a day and therefore one must consider the
feeding schedules on the websites.
ii. Feeding age.
There are some communities in this country that believe that there are some pizza diets that are
meant for elders and others are meant for young people and therefore one must consider pizza
categories while designing the website.
iii. Communal Faith.
In this country the community does not fully feed on pizza from pork or bacon and therefore the
web design should not display any pizza from those products or their information about prices or
images.
Part 2
a. The reflection of Hofstede’s dimensions
The pizza Hut in New Zealand somehow reflects the Hofstede’s dimensions of New Zealand
national culture in that the it is able to offer a variety of products that are able to suit all people of
the different categories which includes the pizzas, sides, drinks, deserts and deals which are able
to cover the various people’s cultural dimensions in Hofstede’s dimensions which includes the
individualism, masculinity, collectivism, femininity, indulgence and restraints.

6PIZZA SHOP OWNER DATABASE DESIGN
b. The differences of the Pizza Hut website designs
In this case I decide to discuss the differences between the pizza hut design in new Zealand and
pizza hut design in Saudi Arabia according to the various Hofstede’s dimensions as follows.
i. The pizza hut in Saudi Arabia website has a fast loading speed compared to the pizza
hut in New Zealand and this is due to less content loaded in the website.
ii. The pizza hut in New Zealand website however has better interaction due to various
products links than pizza hut in Saudi Arabia which has only one page of images
without other categories.
iii. The pizza hut in Saudi Arabia is hard to use as there is less information for the
various products offered unlike the pizza hut in New Zealand which has various
options.
iv. The pizza hut in Saudi Arabia is able to show the geographical location of the clients
which is a great feature unlike the pizza hut in New Zealand.
v. The pizza hut in Saudi Arabia is able to display the discount offered to the clients
unlike the pizza hut in New Zealand that only provides the products details without
any discount or free services.
vi. The pizza hut in Saudi Arabia home page design is simplified without much content
to keep on scrolling downwards unlike the pizza hut New Zealand which has a lot of
content and lengthy web pages designs.
c. The website more understandable and easier to find contact details on.
Between the two selected pizza hut websites both in New Zealand and in Saudi Arabia pizza hut
websites there are various differences in terms of ease to understand and ease to get the contact
details as discussed below.
i. Website is more understandable when using a screen reader
The New Zealand website is more understandable compared to the Saudi Arabia pizza website
this is due to various reasons which includes the following:
a. It provides more links to the various products categories including the pizzas, sides,
drinks, deserts and deals.
b. It provides the content describing the various products offered which offers a clear
insight about the product.

7PIZZA SHOP OWNER DATABASE DESIGN
c. It provides more graphical representation details about the products offered to the
viewers.
ii. Website is easier to find contact details
The Saudi Arabia pizza website on the other hand is able to display the contact details more
clearly which make it possible for the viewer to find the Saudi Arabia pizza website contact
details compared to the New Zealand hut pizza website and this can be justified as follows:
i. The Saudi Arabia pizza website has a small page to scroll downwards and thus it is
easy to get the contact details compared to the pizza hut new Zealand website which
is very lengthy to be scrolled downwards.
ii. The Saudi Arabia pizza website also has other social media links on the footer section
represented using the icons like the face book and twitter which are easy to identify.
iii. The Saudi Arabia pizza website also has a pop up form prompting the visitor to enter
their location and area to get the deliveries and this also improves the contact level of
the website.
Therefore in terms of contacts the Saudi Arabia pizza website is more detailed than the Saudi
New Zealand hut pizza website.
