Management, organizational, and technological factors can impede adoption of internal corporate social networks. Management issues include a lack of incentives for employees to use new social software. Organizational issues include resistance to change from employees accustomed to traditional work practices. Technological issues include social networks that are difficult to use, lack relevant content, and do not demonstrate clear job benefits. For example, NASA's internal social network called Spacebook failed because it did not consider organizational culture and politics or explain how the network would help employees' work.
