In the Age of AI, Human-Centered Design is Crucial

For the last 40 years, you've championed the use of human-centered design, helping clients weather seismic technological shifts. As AI stands to bring massive change, are there any examples of other technological shifts that could help provide a roadmap for what’s coming?

David Kelley: The world has been through all kinds of shifts. The personal computer. iPhones. The internet. AI. And in each one, the technology was the shiny, exciting thing, but it took some insight, some creative leap to figure out how people would actually interact with it to make it successful. The one that was most impactful in my life was the move toward personal computing. When I was young, computers were these big machines in the basement. But as they became more accessible and more human-centered, they made explosive inroads into people's lives.

The most famous piece that IDEO worked on was the Apple mouse. It was our project—we invented the technology and did the industrial design. But the fun part was figuring out how people would use it. On the engineering side, we were trying to make it very accurate. If you moved the mouse one inch on the table, it would move an inch on the screen. But as we did more and more user testing with different kinds of people, it became clear that that was a complete waste of time. The human brain understood what was happening—you didn't have to make it the same distance. And because of that insight, we were able to make the mouse very cheap. Which has a lot to do with why it's successful—the cost is inconsequential.

Do you see parallels between that moment in time and today, when so many technologists are trying to deliver on the promise of AI?

David Kelley: Yes. We're just at the beginning. It’s going to be wildly useful, but at the present time, AI products are going to be hit or miss. It feels like a lot of other technologies we witnessed that didn’t find widespread adoption until someone discovered the right use cases.

Derek Robson: At the same time, AI is with us already, in products we use every day, like Netflix. Right now, AI is very prominent without necessarily having the use cases that you can point to and say, “everyone is using this” or “this is changing the world.” To David's point, we're at the start of a journey.

How crucial is it to implement human-centered design in the creation of AI products?

Derek Robson: It’s fundamental. How many things were meant to be great big breakthroughs, but they just don't work because they don’t take into account what humans want from the technology? In our own AI projects, we co-design with users early in the process, testing concepts to see what they want and need long before a product hits the market.

David Kelley: It reminds me of when Bill Moggridge, one of IDEO’s leaders for many years and a champion of interaction design, was working on the first laptop computer, called Grid Systems. He took it home one night after it was functional, and he came back and he said to me, “This software stuff is way too important to leave it to the software people.” At the time, it had that feeling that you had to be an insider to know how to use it—it wasn’t for the general public. Similarly, AI is far too important to leave just to the technologists—human-centered design is a crucial part of it.

Is part of that the engineering mentality—that the question is often, “can we do that,” rather than, “should we?”

David Kelley: We do see that in a lot of companies, especially when they’re designing for people like themselves. But 99 percent are designing for customers who are not like them.

Over the years, IDEO has worked with thousands of clients. What have you learned from them?

Derek Robson: If you go back through the history of the company, there's a type of leader that has a clear vision of what they want—a sense of bravery, a purpose. They have a dream of how they see the product and their brands evolving. Often, they’re on a path at odds with the rest of the culture. It started with Steve Jobs, and we’ve now had many wonderful clients over the years.

The best ones really get involved with us and embrace the process. And when they do, you find at the end that they've changed too. As much as we are a design and innovation company, we are also an experience company. We take you on a journey of looking at something in a new way and helping you to see the potential of things that aren’t there yet.

‍David Kelley: In the early days of IDEO, we'd send a proposal that included phase one, the human-centered design part, and the client would come back and say, “Could we just skip that first phase and get going?” But that is where our big ideas came from—from understanding what's meaningful to people. Eventually I had the guts to say, “Nope, we can't cut phase one.” That's what we're good at, taking all that information, all those interviews, all those observations, and making a creative leap to a new place.

Where did your confidence in this approach come from? Are there moments that solidified just how important it is?

David Kelley: Early on, we were working for Pepsi, and we went to a place with vending machines. I'm watching people use them, and I'm not getting any real information. But one of my colleagues looked at me and said, “Do you think it's right that the soda comes out at your ankles?” And that's so obvious, right? But the people who built the machine didn't see it. I didn't see it. That wasn't how product companies were thinking back then.

Derek Robson: When you work on something for a very long time, you can start to believe that you know how your product works, and how people use it. And that's not necessarily the case. There are so many things that I've worked on in my life where people use products in a different way than they were intended to be used. And if you don't look at it anew, then you will never be able to move something forward.

Long ago, I worked for a company that was responsible for the Got Milk? ads. And the insight behind them was that people don’t think about milk until they don’t have it—they realize its value in its absence. It’s an insight that can only really come from being deeply connected to what humans want.

Aside from AI, what factors do you see influencing design in the foreseeable future?

Derek Robson: Climate. Human-centered design doesn't mean the human at the expense of everything else. We need to design things so that we’re not destroying the planet. We have to think about not just the composition of materials, but actually how people use those materials. What is going to happen to those materials over time? There's a never-ending list of things we are considering as we design.

David Kelley: As pedestrian as it seems, it all boils down to humans. Even with these big systems problems, you have to ask, what could we design to help people do their part? Think about recycling. It was a systems problem, but also a human problem. Once you had curbside and they came and picked it up, people got behind it.

Derek Robson: We also have to keep in mind that different people have different requirements from the things that we design. Not just from a climate perspective, but also from an ethical perspective. My two daughters think very differently about which companies they engage with than I did at their age. I didn't think about where products were sourced from, or the labor policies for the company. And while that's not for everybody, it is for many young people, and companies need to consider those factors. If they don't, they might not be able to generate the kind of demand they are looking for.

Four decades in, what are you most excited about for IDEO’s future?

Derek Robson: The best work for IDEO is still ahead of us. The mindset of this place is that the next project is the most important project. We're about solving problems, but we're also about asking bigger questions. And we're at a moment where there are so many questions that I think we are perfectly placed to help people answer.

David Kelley: I'm really looking forward to the variety. We're being trusted to do more interesting, diverse things than we ever have before. The mashup of what we learn in all those diverse places and putting that together gives IDEO a kind of database of insights that’s extremely valuable.

Derek Robson: When I joined, we had one team working on the collection of poop for a medical company and another redesigning a government system. The compounding effect of working on different things is what makes us unique. And the kinds of people that work on those problems are probably the most interesting and diverse set of creative people you are ever going to meet. We often say that the team of an IDEO design project sounds like the start of a joke. A mechanical engineer, an ethnography PhD, a physicist, and a doctor walk into a room to solve a problem. I don't think there's any organization on Earth with the diversity of creative talent and working on the variety of work that we have. And I’m excited for what we’ll do next.
