I want to browse using my Amazon phone app rather than always searching to find something I might want to buy now or later.
Lead Designer (solo)
Up until late 2011, Amazon only offered the ability to “Shop by Department” on the mobile web. I was tasked to remedy the situation and design a solution for the iPhone and Android apps.
On the Amazon mobile web, customers selected a top-level department and then a sub-department (this is still the case), resulting in them seeing content no matter what, with nodes further down the department “tree” located below the content for the customers to discover. I believed that a better experience would be to present the customer with the entire tree and let them choose when to see content rather than displaying it after an arbitrary number of taps.
After a review of relevant external research plus discussion with my peers, I proposed that we put the customer more in control. I created a presentation showing stakeholders a range of options along a continuum as well as what experience the competition at the time was providing to their customers.
I subsequently explored many ideas, landing on one with an “All…” at the top that would jump into content and then each sub-department beneath, allowing customers to continue navigating down through departments. Above these list items I designed a carousel of products (images only), primarily to help customers better understand what they selected. I originally wanted to provide more clues before the customer selected an unknown department, but it was deemed too resource-intensive so was dropped.
To test my idea, I created and ran one paper prototype study, which found this model seemed to work, and then another two studies where I created a working prototype on my iPhone using a 3rd party app called “Dapp”, which also supported this model.
Customer satisfaction increased. A moderate percentage of customers now shop by department from the phone apps – but not as many as we were hoping for. We checked the box but did not seem to be delighting customers.
At a later time I explored the idea of using a vertical split-view, where the customer started with the list on the left but could drag the content that was peeking in view from the right edge into view, pushing the list such that it peeked along the left edge.
I worked with the Search team, which took ownership of the feature, helping to guide them in the direction of continuing providing customers with the ability to navigate further at each department level. They came up with a nifty way to also provide more of what customers also clearly want, which is to be able to see more products at each level than I had originally provided.
