The global supply chain is incredibly complicated, with millions of ships and airplanes and trucks bringing goods thousands of miles across the world, crossing national boundaries, and changing hands along the way. If that’s totally overwhelming to imagine, that’s nothing compared to keeping the pieces of this system moving efficiently. The most baffling thing? Much of this unthinkably complex global system still runs on old-school forms of record keeping: namely, paperwork.
Blockchain could be the technology to change all this. Popularized over the past decade as the structural framework behind bitcoin, blockchain is a digital record of transactions that are cryptographically secured–effectively, a digital ledger that works a bit like a Google Doc. If another person adds to it, you can see the changes, and you know who made them and when. Many industries are moving to make blockchain part of their business, and it’s easy to see how such a technology could be used to understand the global supply chain, since it streamlines the complex network of transactions into a verifiable record that every member of the supply chain has access to.
But blockchain itself is technologically complicated, and people along the supply chain need it at different times for different reasons. For instance, someone scanning pallets of food at a warehouse is simply recording what veggies have arrived and when, whereas a customs officer at a major port needs to know where goods are coming from, where they’re going, and if they meet all regulations before giving their seal of approval.
As blockchain makes its way into the mainstream, it will be up to designers to temper its technical complexity with usability–in short, blockchain will need interfaces. IBM is in the early stages of creating them.
Blockchain’s Challenge: Enough Information, But Not Too Much
IBM launched its blockchain division in 2015, and has worked on 400 blockchain projects for individual clients like the FDA, BNY Mellon, the London Stock Exchange, and Dubai customs. But today, the company is launching a blockchain platform: an easy-to-use product that allows everyone in a supply chain, from customs agents to truck drivers to bank officials, to develop blockchain networks together.
Their design needed to make all the paperwork along the supply chain easily accessible for each person along the chain, presenting the right information at the right time–no small feat for Webber’s team.
Visualizing The Journey Of A Single Strawberry
The design team at IBM approached the platform the same way they approach any type of design–talking to users.
That was especially important when trying to solve the problem of food safety for a newly announced initiative between IBM and a group of food giants including Walmart, Dole, Kroger, and Nestlé. According to the World Health Organization, 1 out of every 10 people get food poisoning every year, leading to 420,000 deaths. But figuring out how fruits or meats become contaminated in the first place is a serious undertaking that typically requires companies to trace the food in question back to the farm it came from. This can take weeks of research, or more–in the 2011 outbreak of salmonella in imported papayas, it took two months for investigators to track down the source of the contamination. That means more people get sick, and companies waste food and lose revenue.
Noi Sukaviriya, the UX lead who worked on IBM’s designs for the food safety blockchain, spoke to retailers, distributors, suppliers, and food safety officials throughout the research process. She found that the people trying to track down where food comes from often rely on phone calls to distributors and suppliers, who can’t always provide information. There’s no way to know if the information provided is accurate or complete, and it can take weeks to find the precise origin of the food. It could be a world away.
But while blockchain collects all that information in one place, and ensures that everything is accurate, it doesn’t make parsing or organizing that information very easy. That’s Sukaviriya and her team’s job–to highlight the relevant information to the right person when they need it. “I don’t think that blockchain is what the users have in mind really,” Sukaviriya says. “They don’t really understand at the deep level what it will do. But what is important is the ability to get to the information that they can trust.”
But while the IBM designers want to make the process legible for all users by relegating the technology in the background, they also want to be clear that it’s blockchain making everything happen–communicating the trust clients should feel in the system. Sukaviriya says her team is playing around with creating some kind of digital stamp that would add an extra visual cue to users that a document can be trusted. Ultimately, Sukaviriya hopes that her design will make blockchain accessible for small, independent farmers and suppliers around the world so they can continue participating in the conglomerate-dominated global supply chain. “It seems all high-tech,” she says. “Our dream is to have farmers be able to put information in even though they [aren’t] high-tech.”
As blockchain becomes more deeply integrated into global trade, creating its interfaces is surely a design job of the future.
