Abstract ¡§Human Needs Drive Technology.¡¨ Since internet comes into action, it brings dramatic changes in human culture. Internet technology does not change only the way of communication or how the business activity moves, but it also creates a whole new life model. Especially after the rising of instant messaging software, the real-time communication model is formed. Many studies on instant messaging focuses on the pros and cons of the software itself and the benefits it has generated. Besides, their study groups are more focused on people with specific roles, such as sales, marketing staff, or students. The results obtained often do not cover the aspects on people with multi-roles. This study report takes EMBA students as the object of study, mainly because they carry the characteristics of both a student and a business man, whose behavior may lead us to see the general value that the instant messaging can generate. The study focuses on the behavior and motivation of EMBA students using instant messaging software, and it further discusses the changes that the instant messaging can bring at their study and their jobs. 9 EMBA students are chosen to conduct the case study, interviewed face-to-face and via instant messaging. The study finds that the instant messaging software have brought very positive benefits for EMBA students in their jobs, school work, and even in their interaction with their family.
