Taco Bell

The Project

While at Deloitte Digital, Ashley 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 preparation time.

Over the course of one month Ashley 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. Ashley and team ran usability tests at Taco Bell Headquarters test kitchen and iterated the design based on user feedback and observations.

Ashley also did some an extensive heuristic evaluation of Taco Bell’s website and native mobile app.

Stakeholder Interviews & A/B Tests

Ashley lead the team through interviews with 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

After spending a week in various Taco Bell’s observing and interviewing the employees, as well as conducting A/B tests, Ashley and the team was able to start concepting by building a few different prototypes to test against Taco Bell’s current KDS. The team 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.
