Lucy Suchman’s research fundamentally changed our understanding of “whether technology is suitable for human use.” Her study of photocopier users at Xerox revealed that the problem wasn’t that users “didn’t know how to use it,” but rather that the technology’s design itself was flawed.
Traditional views assumed users would follow instruction manuals step by step.
But Suchman found that users actually relied on “improvisation” to solve problems—such as trial and error, observing others, or hands-on experimentation.
Many designs force users to conform to the machine’s logic, while she argued that technology fails when it ignores the messiness and collaboration of real-world scenarios.
She advocated for directly observing users rather than relying on theory, which became the foundation of UX design.
Later, she pointed out that AI systems often pretend to “understand” humans but actually overlook the complexity of real behavior—like the robotic responses of customer service chatbots.
Her research advanced user-centered design, reminding us that the standard for “good usability” is whether technology aligns with real human behavior, not just superficial “high-tech” features.
