The product:

Tacoshak is a local chain of restaurants which strives in offering a wide menu of taco styles and combos. Tacoshak targets customers like commuters, workers and students who lack the time or ability to prepare a family dinner.

Project duration:

October 10th 2022 to January 26th 2023

Project overview

The problem:

Busy workers, commuters and students lack the time necessary to prepare a meal.

The goal:

Design an app for Tacoshak that allows users to rapidly and easily order and pick up just made tacos.

My role:

UX designer designing an app for Tacoshak from conception to delivery.

Responsibilities:

Conducting interviews, paper and digital wireframing, low and high-fidelity prototyping, conducting usability studies, accounting for accessibility, and iterating on designs.

Understanding

the user

●User research

●Personas

●Problem statements

●User journey maps

User research summary:

To understand the user I am designing for, I did journey maps and research to

fully visualize why and how busy workers seems not to have time enough

to cook a meal. Which with a user group could be a lack of organization.

This user group confirmed initial assumptions about Tacoshak customers, but research

also revealed that there are other factors that produce the lack of time, such as obligations, interest, work location, long commutes or challenges.

Time

Busy working adults who does not have time to cook their meal and not enough time to order by phone.

Accessibility

Current apps do not support assistive technologies.

Ordering process

Avoid ordering food because it takes so long doing it on the phone or food delivery apps.

Pick up and delivery

Not options available for pick up or other delivery addresses

Persona: Larry Homes

Problem statement:
Larry is a warehouse manager who needs a fast and easy way of ordering and paying for food because of his busy schedule and does not have a daily scheduled lunch time.

Persona: Michelle Mcbee

Problem statement:

Michelle is an ambitious professional working towards a promotion on a business administration firm. She needs a fast and easy way to order food without wasting time.

User Journey

Mapping Larry’s user journey revealed how a fast way or ordering food can be so helpful for very busy users.

Starting

the design

●Paper wireframes

●Digital wireframes

●Low-fidelity prototype

●Usability studies

Paper wireframes

Every wireframe along with iterations focused on a really fast ordering process and choice making process. Allowing the user to have the right amount of options on food and time ordering.

Paper wireframes

Producing a set of wireframes equipped with accessibility technologies and offering the right options to choose from.

Digital wireframes

Producing a home page from where they can see some food ítems and specials, along with options for favorites, locations, food menu and order tracking.

Digital wireframes

I added the favorite button for faster future purchases along with an order now button which takes you straight to the confirmation page.

Digital wireframes

On the cart I Wanted to place the button and the amount to pay right away for a faster confirmation. Also some recommendations are showing along with an “+” sign if need of increasing the order.

Low-fidelity prototype

Connecting the complete set of wireframing to produce the main user flow, which consist on ordering an item from different sections, so the prototype could be used in a usability study

View prototype here: Low fidelity prototype

Usability study: findings

I conducted two rounds of usability studies. Findings from the first study helped guide the designs from wireframes to mockups. The second study used a high-fidelity prototype and revealed what aspects of the mockups needed refining.

Usability study findings:

Round 1

1 Hard to go to home screen between tasks

2 Payment button misplaced in cart section

3 Cart access

Usability study findings:

Round 2

1 The user flow works fluidly

2 Reward points must show on home screen

3 ”Buy now “ button is super quick to order a meal

Refining

the design

●Mockups

●High-fidelity prototype

●Accessibility

Muck ups

Early designs offered different options to order from the home screen, but after usability studies, I modified the navigation bar by adding the cart icon and text on each button. Also I Improve the buttons of the menu, favorites and tracking order.

Muck ups

I created a new button for fast purchases, which offers an item from your favorites right on the summary page.

Muck ups

After the second study: It shows that the user had to go to the profile screen to see how many reward points were available. I added the reward points to the home screen, next to the address.

Muck ups

High fidelity prototype

A cleaner user flows aloud the user to order a meal and track it. Moreover, add items to favorites and express buying is available.

Accessibility considerations

Providing buttons of assistive features right in the home page

Use strong colors and icon on the buttons, along clear icons in the rest of the prototype for an easier understanding

Used photos of the tacos to visualize the item they are ordering

Going forward

●Takeaways

●Next steps

Takeaways

Impact:

The app makes users order food in under 3 clicks from the home screen, making it extremely fast and likable. The shuffle button provides another option to choose from, also ready to be paid

What I learned:

While designing the app I learned how wide the spectrum of iterations is, focusing on accomplishing a design which can provide assistive and accessible features. How to conduct a proper UX study and iterate from there using the feedback was where I learned the most.

Next steps

Launch a new version of the app with real time delivery tracking, to bring certainty and legitimacy of their delivery.

Conduct another round of usability studies to validate whether the pain points users experienced have been effectively addressed.

Add a ”Send to” feature to be able to send food to an address with our having to add it to your frequent or regular addresses.
