Less than a year after the iPad was released, I lead the design of the iPad shopping app for Walmart - a first for the world's largest retailer. After a series of focus groups we learned most competitor apps fell short in finding and filtering results down to something manageable. The key challenge was to design a shopper experience that demonstrated key traits of the Walmart brand — straightforward, friendly — while wrangling with Walmart's vast inventory. This app helps bring Walmart into contention with online giant Amazon, while retaining the advantage of local store presence; allowing shoppers to browse vast inventory, while taking advantage of local store availability, local delivery, and in-store pick-up.
