Eventually, I removed many of the e-commerce features from the flows, getting rid of checkout, pickup, delivery, and even the shopping list. In addition, I got rid of all the editorial content.
Much of this was informed by taking a flow-based approach to app development — simply wiring up potential screens helped me understand where the concept was falling short, and which aspects either didn’t make sense or didn’t fit with the needs of my intended user.
To flesh out and formalize these user flows, I created a draft journey map built atop the formative research I had performed to date, including the experience sampling results. Building this document forced me to view Nearbuy from the perspective of the shopper I was designing it for — and helped me understand which fancy add-on features were superfluous to the core concept.
