Knowledge Architecture recently completed a study on social media activies of over 250 of the largest architecture and engineering firms in North America. Over half of the architecture and engineering firms we surveyed are actively using social media. Of those firms, almost all of them were using social media to market their firms, which did not come as a surpvise. However, we were surprised by the number of firms who were using social media for purposes other than marketing, such as recruiting and retention, research and development, and knowledge management. this session will contatin three parts: 1) Presentation of research findings 2) Discussion of key insights and trends yielded by our reserch 3) Presentation of case studies which indicate where social media is heading for architects and engineers.
