Local Farm Shop Application: Interface Design, Development Report

This report details the interface design and development of the Local Farm Shop application, which aims to provide users with features for purchasing food, drinks, and gift items, as well as booking restaurant reservations. The design process involved creating mockups in Balsamiq, using wireframes to represent application features, and adhering to Nielsen's Heuristic principles to ensure usability and user-friendliness. The application includes functionalities like sign-up/sign-in, menu options, and a feedback mechanism. The report reflects on the user interface, user requirements, and justification for the design choices, highlighting factors like business and user needs. A similar application, Keelham Farm Shop, is discussed for comparative analysis. The conclusion summarizes the entire interface design process, emphasizing improvements made based on feedback and the implementation of Nielsen's heuristic principles.

Abstract
An application Local Farm Shop is developed to provide features like food items, drink items and gift
items to users of application. For the application, the mockups are created in the tool Balsamiq. The
wireframes are used to represent the features of the application Local Farm Shop. There are 4 unique
stages in the Local Farm Shop. In the first stage, the two alternative designs are created for the application
Local Farm Shop. In the second stage description of the design selected is carried out. After the option is
selected the interface is designed and then documentation is created for the interface design. In the third
stage, the feedback is noticed for interface design. The feedback is given other team members. In the last
fourth stage, the last documentation is made for application Local Farm Shop. Interface is design for
customer who wants to buy food item, gift item and drink item. The interface can be further improved.
Introduction
The application Local Farm Shop is developed for providing the different features like gift items, food
items and drink items and restaurant can be book using the application. The application provides different
unique functionality like sign-up option, sign-in option, menu choice and other different options. A logout
option is present on each interface screen of application local Farm Shop. The back button is also there on
each interface screen of application local Farm Shop whenever user can go to back screen and navigate in
between screen. There are majorly three different categories of application Local Farm Shop which are
gift category, drink category and food category (Zhang & Adipat, 2005).
For creating the application Local Farm Shop, a Nielsen Heuristic model principle is used. This model is
used to create interface screen. The features linked with heuristic principles are search button, back
button, user-interactive and many more. The Nielsen heuristic principle used is efficiency of use, help,
and documentation, diagnose, visibility of system status. These all heuristic principle are used in
application Local Farm Shop (Bal,2013).
There is one unique feature in the application Local Farm Shop in which the menu item is present on each
screen like welcome screen, home screen. In welcome screen the menu item is present but the options are
not accessed until user does not sign-in or sign-up I the application Local Farm Shop. There is also a
feedback option where user can ask their queries and can submit their reviews and feedback.
Reflection for Local Farm Shop application
User interface and design
The application Local Farm Shop is developed to provide various facilities like user can book restaurant.
There are two different packages one is golden package and one is platinum package. User can view the
package details and according to that can book the restaurant. The user can purchase various items like
drink items, food items, and gift items. There is an option of description in which user can read the
description of product and then can buy the product (Pommeranz, Broekens, Wiggers, Brinkman &
Jonker, 2012).
The application local Farm Shop is based on Nielsen heuristic principles. The background color used in
the application Local Farm Shop is according to theme of application.

User requirement
The Local Farm Shop application is based on the user requirement. The user requirement was to make
the application user-interactive and use the font appropriate. All the features of the application should be
clearly visible on the application Local Farm Shop. There is one advanced feature in the application Local
Farm Shop in which user is not allowed to use the services without sign-up or sign in the application
(Cahill et al., 2018).
Justification for application Local Farm Shop design
The aim of the application is to provide various different functionalities like buying the food items, drink
items, gift items and can also book the restaurant according to need. There are so many payment choices
available to customers. Payment choices are like cash on delivery, debit card and card. The whole design
of interface screen is based on Nielsen Heuristic model. All the heuristic principles are implemented for
designing the application Local Farm Shop. There is also a referral option in which user can apply the
referral code and can get extra benefit from the application Local Farm Shop. The logout functionality
helps the user to get from awkward state. The log out button is present on each interface screen which
helps user to exit from application (Dick, Hull, & Jackson 2017).
Factors for application designing
For developing the application Local Farm Shop, factors used for developing the application are business
requirements and user requirements. The design principle applied for developing the application is
Nielsen Heuristic model. The user requirement related with application is font size, background color and
use the application without facing any problem. The buttons and labels are properly aligned on the screen
of application Local Farm Shop. The features should be clearly visible to the user and the functions
should be basic so that a new user can also use the application without facing any problems. The unique
functions in the application like logout functionality, menu item functionality and back button
functionality. The user needs to first sign-in application and then can purchase items from the application
(Horsky, et.al, 2012).
Discussion of similar application
The application Local Farm Shop is used for providing different functions like drink, food, and gift items.
There is one more feature of OTP. When user clicks on payment option and selects the payment option an
OTP is generated for confirmation of payment. The customer can click on Resend OTP option for getting
the OTP again. As search button function helps user to search their desired product. If product is there in
application the product will be displayed otherwise message will print that product not found. A
confirmation option is also there in which when customer clicks on buy button a confirmation message
occurs which waits for user confirmation. If user chooses yes option the user will be redirected to the
payment gateway. There is a unique option in which user can enter referral code for getting extra benefit
in Local Farm shop application.
Keelham Farm Shop
A similar application Keelham Farm Shop is type of application which provides various functionalities
like user can buy food items can select the top trending products from the application. The user can also
get recipes from selecting the recipe option. A unique option is present in which the Shop hires an

employee. If any user wants to get job in Keelham farm Shop he can apply for the application. The
interface of Keelham application is better than Local Farm Shop application.

Conclusion
For the last assessment, a brief summary is developed of whole interface design of Local Farm Shop
application. In this report, all the unique features and functionality is been discussed. A similar
application Keelham Farm Shop is being discussed. The feature of Keelham Farm Shop is discussed in
this report. I have taken an idea from Keelham Farm Shop application. The concluding design of
application local Farm Shop is being discussed in this report. The final design is completed by analyzing
the feedback and from feedback, the interface design is improved. All the user requirements, system
requirements are briefly discussed in this report. All Nielsen heuristic principles are also implemented for
creating the interface design for Local Farm Shop application.
