PepsiCo's initial efforts led to the creation of a prototype dashboard using Power BI. However, this prototype lacked the sophistication and flexibility required to meet PepsiCo's complex needs.

DOOR3 Solution

DOOR3 delivered a tool that revolutionizes how PepsiCo interprets data. The DOOR3 project team delivered a solution that not only met PepsiCo's immediate needs but also set a foundation for future expansions and external collaborations.

Challenge

With both English and Arabic spoken in Saudi Arabia, one of the biggest challenges with this mobile experience was designing an application that is as intuitive left-to-right as it is right-to-left. DOOR3 aimed to create a beautiful user experience in both languages, with flawless transitions in-between.

Challenge

Dr. Treat came to DOOR3 with only an idea, seeking to establish a requirements list for an MVP, solidify their user flows, and generate compelling designs.

DOOR3 Solution

It took less than 6 months our team to transform Dr. Treat’s concept into a complete MVP. DOOR3 packaged 24/7 in-app urgent care contact, scheduling, document storage, and billing management into an app that is intuitive and incredibly effective for veterinarians, pet caretakers and their pets.
