Key features of the new interface design based on the design principles
Invite to action
When opening the website, the customer is greeted by a pop-up window that automatically appears. The user can fill in their zip code, which means that mistakes are minimised because they cannot miss this step, as it is crucial for new customers if the company can deliver orders home. The user is also invited to take action by receiving tips in the shopping cart for items that the user may have forgotten they need.
Make it understandable and familiar
Keeping a common thread throughout the interface’s layout has been prioritised so the user can recognise and get used to the interface. An orange colour has been used on the “Call to action” buttons” and a green colour has been used on the “Add” buttons”. Furthermore, users can now select items and create boxes across all pages to display information from different tabs.
Support execution and evaluation (feedback)
A pop-up window appears after changing the delivery day, as it’s important to give users feedback after making changes. A progress indicator shows the steps from choosing the box to adding it to the shopping cart. Users can go back a step if they made a mistake. Feedback from user tests improved navigation, such as adding more interaction between the guide page and primary boxes.
Keep focus and don’t get distracted
The opacity of objects changes when, for example, maximum selections are made. Once enough objects have been selected, their opacity will be reduced to indicate that no additional selections can be made.
Don’t force people to keep too much information in their heads
At the end of each selected box, a summary of the contents is available to the user. This feature prevents users from memorising information by showing them everything they have in their box.
More straightforward navigation for the users
We have improved the user interface by removing irrelevant information and creating a more logical and streamlined flow of relevant information. Through user testing, we identified the mental model users follow when navigating between different functions, and we have implemented a common thread to avoid confusion and ensure a consistent user experience.
Make components large enough
Buttons are designed to be well-spaced and large enough to avoid incorrect clicks. As we were creating designs for a mobile screen, we had limited space to work on compared to computer screens.
Boost customer engagement
Gamification was integrated by linking rewards when inviting friends, creating recipes, saving and sharing them with others. The scoring system tracks users’ progress and records their score history to provide valuable insights for informed decision-making.
Contributing to a greener planet
A calendar designed to choose the delivery day and time that also shows “green days” for delivery. Users can choose environmentally compensated delivery by selecting green days in the calendar. This helps to reduce the environmental impact of the package delivery.
