Interface Usability Case Study: Design Principles for Farm Shop App

This case study examines the interface usability of an internet-based application designed for a local farm shop, focusing on the interaction between the owner and customers. The application enables the owner to sell produce with home delivery and allows customers to purchase products without visiting the shop. It also includes restaurant booking and the option to book a whole restaurant for functions. The design principles emphasize clear communication, seamless transitions, and user-friendly navigation. The main usability goal is fulfilling user requirements, such as buying fresh products with same-day delivery and booking restaurant tables. The user experience aims to provide seamless access to all application benefits, including product purchases and restaurant bookings, with smooth guidance and direct contact with the owner for complaints. While a negative aspect is the reliance on a high-bandwidth internet connection, the design's positive aspects include ease of use and a synchronized sales process for the farm shop. The interface is deemed appropriate for minimizing costs associated with a physical storefront, allowing the shop to operate primarily as an inventory and dispatch center.

Introduction
This assignment which is a case study of an internet based application for a local farm
shop. The proposed online application for the farm shop mainly deals with the interactions
between the owner and the customers. And this assignment describes the needs and requirements
of users as well as owners from this application (Endsley, 2016). The owner can sell his produce
by enabling home delivery to customers. And the customer can buy any product from the farm
shop without personally visiting the shop. This application is designed to fulfil these
requirements. Additionally this application provides restaurant booking in the nearby area. By
using this application table can be booked in restaurants. Another additional feature of the
application is if the customer wants to host function or parties they can book the full restaurant
for one day. These are the main features of the application.
Discussion
Targeted users: Since this application is for a local farm shop, the targeted users are
mainly the local residents of the city. As the shop is a small business, it cannot deliver goods
outside the city of the country (Fu et al., 2018). So, for this reason targeted users for this
application are the local users.
The influencing design principles for application design: In the application design
there are clear communication between the user/customer, shop owner, the bank for online
payment, and the restaurant owners (Thies, 2015). All objects are shown properly on screen.
Which shows that the application is designed with care and expertise. Transition between pages
are seamless. And the navigation is also very user friendly.

2INTERFACE USABILITY
The goals of usability: Fulfilling the requirements of the user is the application’s main
usability goal (Thomas, Oppermann& Krogsæter, 2017). The user wants to buy the fresh product
from the shop and get the delivery the same day. Also the user wants to book a table in a local
restaurant. In this prototype all the requirement of the users are taken care properly. The usability
goal of this application is to satisfy both the customers as well as the shop or restaurant owners.
The goals of user experience: The main goals of user experience is that the user can
avail all the benefits of the application seamlessly. They can buy products, book restaurant online
using their phones or computers. The user also can be guided smoothly by the suggestion of the
application for buying the next product or to book the next restaurant (Shneiderman et al., 2016).
The user also get the same day delivery of the product he or she may buy. In the about us the
phone number of the owner is given, so that for complaints or for grievances the user can contact
the owner directly.
Positive and negative fact of the Designs: The interface that is design has negative
factor as well as positive factor. The negative factor is that the user who is uses the application or
the admin of the shop owner, none of them can use the design of the application without internet
connection. Both of them needs high bandwidth of internet connection. The positivity that the
interface design offers is the user can use the interface very easily as the design guides smoothly
through all its pages (Page, 2014). The user can use the design for ordering their daily
commodities from their home itself. There is an advantage of the local farm shop as well. They
can display all their products in a categorized way that is a more synchronized process of selling.
Best design Option- This interface that is designed is the most appropriate one for the
local farm shop as they can minimize the cost of making a front end shop for the customers to

buy their products. They can only store their products as inventory and can dispatch them to the
customers accordingly.
Conclusion
A complete and detailed discussion of the application for the local farm shop is done in
the assignment. The local farm shop application is an internet based application which provides
various facilities to the customers as well as to the owner of the farm shop. The application
provides a very good platform to both parties to buy and sell product online. The case study also
provides a keen insight to the influencing design principles, also it discusses about the usability
goals and the user experience goals as well as the negative and positive influences of the design
of the local farm shop online application.
