Introduction:The needs and expectations of health professional educators and learners are evolving. Therefore, physical and virtual learning environments will look and function differently in the future. Understanding desirable, feasible options for educators and learners, including online, in-person, hybrid, and extended realities, is critical. We designed and facilitated a faculty development workshop that adapted Lean Startup methodologies and role-modeled effective virtual teaching skills to engage stakeholders in generating ideas to inform future development of learning spaces within one national academic medical center. Methods: We facilitated the 3-hour workshop with an interprofessional group of health professional educators, learners, and administrative staff. The workshop included asynchronous prework and synchronous microlectures, small-group activities, and large-group report-outs. We employed Lean Startup methodologies to promote divergent thinking. Each small group had a dedicated convener and scribe. A designated chat moderator, social media facilitator, and several audiovisual staff provided support during the workshop. Results: More than 4,000 ideas were generated by the 350 participants. Participants reported that prework, microlectures, and small-group activities were successful in preparing them to engage in rapid idea generation and propose potential solutions for future learning spaces within health professions education. Discussion: The workshop, which utilized a rapid idea generation and Lean Startup methodologies format, was successful in producing an abundance of original ideas and potential solutions for future learning spaces within health professions education. As reported through postsession evaluation, participants valued the opportunity to contribute ideas and co-create potential solutions to guide future planning and feasibility studies.
