Why would the user choose Foodie Café?

Understanding the challenge

Giving access to users to pick ingredients to make their own meal might sound easy. But, according to our research, the more choices you present your users with, the longer it will take them to reach a decision. Hence, we cannot give too many options to users. The challenge is to decrease the number of choices and still get enough input from the users to customize their favorite meal resulting in their satisfaction.

Proposed solutions

Creating an app that lets users hit ingredients and add the preparation method to any meal they want might help some people with different food restrictions such as allergies. According to our user research we learned that our target users are mostly the ones who tend to order healthy meals. Therefore, we decided to prioritize healthy ingredients in the customize section to better understand the users thinking in the test phase.

Research

01 RESEARCH

Key findings from user surveys & interviews

" Don't make me think, I'm starving! "

I conducted user interviews with six fast-food fans and surveyed 25 individuals with different food restrictions from different demographics. Afterwards, I conducted card sorting with five potential users. Fortunately, one of them was a chef who is a fan of fast food. Her points of view helped me to convert our data into information architecture.  

Why did we pick a mobile app over a website?

Why did we add a ready menu in addition to a customize menu option?

Card sorting

These grouping of cards are from the perspective of a developer, a chef, and a graphic designer who all are fans of ordering fast food.

Analysis

02 ANALYSIS

We generated affinity diagrams by gathering data (ideas, opinions, interview results, competitive analysis) and organizing them into groupings based on their relationships. Then we went through the survey results where the persona Patricia was born. Next, we created a key path scenario. We joined Patricia on her journey of using the app to place orders.
