How it is used, whether it enhances or reduces productivity, and how enterprise-friendly design and use might evolve are open questions. We examine attitudes and behaviors in a large, technologically-savvy organization through abroad survey and thirty focused interviews. We find extensive social and work uses, with complex patterns that differ with software system and networker age. Tensions arise when use spans social groups and the organization’s firewall. Although use is predominantly to support weak ties whose contribution to productivity can be difficult to prove, we anticipate rapid uptake of social networking technology by organizations.  \nCategories and Subject Descriptors  \nH.5.3 .

By late 2008, MySpace and Facebook each had 60 million U.S. users and accounted for 6%-8% of all time spent online [17] . As is often true of digital communication technologies, students are enthusiastic adopters. Whether or not it enhances academic achievement, it is of value to students, for whom social networking can vie with studying as their primary occupation. Enterprise acceptance of a new technology often lags student use. As discussed in [13], in the 1990s some researchers still argued that organizations would discover that email reduced productivity and remove it. Ten years later, industry analysts made similar arguments about instant messaging—IM was a way students wasted time and should be avoided by organizations. Now email is mission-critical and some managers and executives use IM. In the past two years, SNS has established a significant presence in enterprises. Facebook, initially restricted to universities, opened  \nPermission to make digital or hard copies of all or part of this work for personal or classroom use is granted without fee provided that copies are not made or distributed for profit or commercial advantage and that copies bear this notice and the full citation on the first page.

One-third of the employees in the enterprise we studied were in the Facebook company network. We found an equal number of employees with LinkedIn accounts. Professionaloriented LinkedIn had quadrupled in size to over 25 million members in one year [12] . What if anything are all these professional users doing with social networking software? Enterprise adoption of social networking software is far easier, and preventing it more difficult, than was true for earlier technologies. This raises questions. Do these sites enhance productivity? Can utility for enterprises be increased? What new issues will arise for these new user populations?  \nIn early 2008, we conducted this research in Microsoft, then an organization of 88,000 . Although not a typical enterprise, it is typical of the early adopters of email and IM that foreshadowed subsequent wider use. We briefly review social networking software history and research, and then describe our study.  \nBACKGROUND AND RELATED WORK Social Networking Sites  \nSocial interaction was present in early terminal-based computers, as we","cbCaicL7aXBLZqDe","https://ap.wps.com/l/cbCaicL7aXBLZqDe","pdf",556543,9,"English","# Abstract\n## Research questions and motivation\n## Study approach\n## Key findings: uses and patterns\n## Organizational tensions and firewall","[{\"question\":\"What does the study examine about workplace social networking?\",\"answer\":\"It examines professionals’ attitudes and behaviors in using social networking software at work, including whether use enhances or reduces productivity and how enterprise-friendly design and use may evolve.\"},{\"question\":\"How was the research conducted?\",\"answer\":\"The study used a broad survey and thirty focused interviews inside a large, technologically savvy organization.\"},{\"question\":\"What tensions arise from workplace use of social networking sites?\",\"answer\":\"Tensions emerge when social networking use spans social groups and intersects with the organization’s firewall.\"}]","When Social Networks Cross Boundaries - A Case Study of Workplace Use of Facebook and LinkedIn - Abstract | PDF",1790263712]
