My Role 

Lead UX Designer - Kitchen Display System (KDS) 

The Project

I worked directly with the Operations Manager at Taco Bell to redesign the screens in the kitchen that are used by the food preparers.  

The goal of the project was to decrease employee errors while preparing food, decrease the training time, and increase speed of preperation time. 

Over the course of one month I was the lead UX designer in charge of conducting interviews with business stakeholders and end-users, and working with one other UX designer to create three different Axure prototypes to test against the current Taco Bell KDS, ran usability tests at Taco Bell Headquarters test kitchen and iterated the design based on user feedback and observations. 

I also did some work on Taco Bell’s native apps and did an extensive heuristic evaluation of Taco Bell’s website, neither of which are shown here.

STAKEHOLDER INTERVIEWS & A/B TESTS

We interviewed business stakeholders from operations, training, new product, restaurant transformation and engineering, visited three Taco Bell stores, and interviewed 17 in-store employees. The current KDS sits about 3 feet above the food preparer’s heads, so they are constantly looking up at the screen to see what the customer ordered and looking back down to prepare the food. How much an employee can remember and retain was one of the most important problems to solve for. A/B testing helped us identify which layout resonated with the majority of people.

PROTOTYPE. TEST. REPEAT.

After spending a week in various Taco Bell’s observing and interviewing the employees, as well as conducting A/B tests, we were able to start design by building a few different prototypes to test against Taco Bell’s current KDS. We spent three days in the test kitchen and ran a total of eight tests with six groups of Taco Bell employees, all with varying experience working at Taco Bell.

I am not able to share the proposed work, but we put together three options utilizing various technology, one which I created a video to show how Mixed Reality could be leveraged to accomplish the goals of the stakeholders and alleviate the pain points of the employees.
