During our recent renovation planning process, the MIT Libraries was offered the opportunity to act as client for an MIT Sloan School of Management student seminar. The library provided a problem statement, and within two and a half days, five student teams learned and applied a business approach to design thinking to develop solutions for the library, presenting results to faculty and library administrators at the end. These results were contrasted with data gathered from traditional assessment tools, indicating areas for further study or exploration and key principles to fold into the schematic design process.
