Project background

We are building a new app to help people quickly order healthy food and book reservations. We need to find out if the main user experience of ordering food and making reservations is easy for users to complete.

We’d like to understand what specific challenges our users might face in the ordering, payment, and connection process, and how we can help them fix those challenges.

Research goals

Figure out if users can complete the core tasks within the app.

Determine the ease of use of the food ordering and reservation app when users try to complete core tasks such as searching, selection, ordering and in-app navigation.

Reduce the time it takes a user to find a restaurant and order food on the app?

Reduce the time it takes a user to find a restaurant and make a reservation on the app?

Research questions

Are there any parts where users are getting stuck?

How long does it take a user to find a restaurant and make a reservation on the app?

What effect does the rating of food have on the quantity of that food ordered? Is there a correlation?

Do users find the recommended associated go together foods helpful or annoying?

What can we learn from the steps a user takes to order a meal?

What can we learn from the steps a user takes to make a reservation?

What additional features does the user request?

What existing product features does the user not need or has very limited and low usage with little effect on usability and non on accessibility?

What features or UI components clutter, reduce visibility or does not help in the searching or selection process in ordering or making a reservation?

What additional information do user require or what finding do they make to finalize their order?

Key Performance Indicators (KPIs)

The checkout process for the food ordering app was analyzed using the KPIs time on task and conversion rate. Time on task measured the time it took users to find and order a meal or make a reservation at a restaurant a dog walker, while the conversion rate measured the percentage of users who successfully ordered a meal or made a reservation.

The complexity and ease of use of the user interface was analyzed using a system usability scale

User error rate: How often does the user get stuck in ordering or making a reservation and do they recognize icons?

Looking at the 3 KPI’s showed a clear picture of user experience when navigating the app between the food ordering service and reservation, comparing the results on the SUS study with the time on task and conversion rate gave insights and actionable feedback into the frustrations or positive experiences regarding the navigations user experience

Among the research goals is to determine the ease of use of the navigation app in ordering food or making reservations, of which it is pertinent that the navigation system is clear and easy to use and also

To determine how easy it is to order or make a reservation, comparing 2 KPIs that measure different parts of the checkout process generates new insights among them is how effective the checkout process is.
