As a study project for the Google UX Design Professional Certificate, I created an app for a food bistro.
The goal is to enable customers with specific dietary needs to order food without worries.

Understanding The Users
User Research

Starting From The Questions
1. How might we make the menu more accessible?
2. How might we make the ordering easier for people who have special dietary needs?

Pain Points

Age: 42 
Education: Bachelor in Literature 
Nationality: Japanese 
Occupation: Housewife
Family: Lives with her husband and four kids in pre-school age

- To make sure everyone in the family has well balanced diet 
- To save time as much as possible when checking the menu and ordering food

Frustrations :
- “Taking care of four kids can be really exhausting; I wish be more efficient and have more time for myself“
- Feels awkward every time she needs to ask for help to check the ingredients in each dish when ordering

Hana is a Japanese woman who has been living in Switzerland for over 10 years. She visits the local bistro everyday, and she is passionate about discovering the daily menu. However, since her young children have different food intolerances, finding what to order can take a long time and usually requires the help of the staff. Hana would like to enjoy her experience in the shop without worries and without having to bother the waiters constantly.



Our ordering app  
will let users easily understand what they can eat 
which will affect those who have dietary needs and/or restrictions  
by quickly filtering out the ingredients they try to avoid

Usability Study

Users need better cues for finding out more options in the filter  

It was observed that 4 out of 5 participants had troubles in finding the sub menu in the filter section. This means that the sub menu in the filter section is difficult to find for most of the users.

"Maybe it would be better to have icons for the ingredient" _ Participant E
"Hmm...I don't see the extension of the ingredients list" _Participant A

Users need different payment choices 

It was observed that 2 out of 5 participants tended to find different payment methods. This means that different payment methods are valuable for some users.

"What if I want to pay with Apple pay?"_Participant B
"So...I'm not allowed to pay cash..."_Participant C

Users need to be guided more intuitively by both a search bar and a list of categories to find the result they want

It was observed that 3 out of 5 participants tried to use both searching by typing and also clicking on the category buttons. This means that 2 filtering functions are necessary for different purposes for most of the users.

"I can use both to find products, but I can not use it to find ingredient" _ Participant C
