Thousands and even millions of the people have been using Blog, Facebook, MySpace, Twitter, and others as a communication medium. Many of them are mobile connected and have made it a daily practices. Interestingly, all these changes are not followed by Onmi International Hospital which it ultimately in 2009 led to the crisis. This crisis was beginning from the customer, Prita Mulyasari, who felt disappointed at the hospital service, and wrote an e-mail to her friend. Suddenly, in a short time the e-mail was disseminated widely on the Internet and produced a lot of support and public humiliation to the Omni International Hospital. This paper aims at explaining the cybcr crisis experienced by Omni International Hospital and how to overcome the problem at corporate level.展开更多
