The system has various interfaces that will allow the user inputs during the system interactions process below are the user interfaces.
The Fitness freak online shop system will be accessed using laptops and desktop computers which will be using Mozilla Firefox and Google chrome browsers, where the access time and speed will be moderately high.
While accessing the system the users require having enough data bundles more than 10mbs to enable efficient loading of the system features including the images of the store products.
However there will be two main users of the system who will be the customers and the workers of the organization.
The system targets many users which will include various groups of people who will be children, youths, and elderly people and therefore the graphics will be attractive to them and the descriptive text will be large enough to be visible by any of the targeted audience also there will be beautiful products for the ladies and nice colors to attract children (Bonczek, 2015).
The system will be highly reliable where the customer’s time will be highly saved since they require shopping for their products from anywhere which is more convenient.
However the customers will be able to have access to variety of the products which he can compare and he will be able to pay using the PayPal method.
The system will provide the customers with the unique login details which they will be using to log in the system and buy or place order; also the workers also will be having the login details that they will be able to use while updating store products.
