Lucy Suchman’s work, her study of Xerox photocopier operators, changed how people think about technology design by emphasizing the importance of real-world context. She shows that people did not follow a rigid, predictable process when using machines such as photocopiers, but instead adapted and improvised. Her research claims that technology should be designed with these human behaviors in mind, considering how people naturally interact with systems rather than expecting them to follow predefined instructions. From technology-centered design to a more human-centered approach, ensuring technology works better for people in real life.
