IDEA DIAMOND: A SYSTEMATIC INNOVATION MODEL FOR SOCIAL NETWORK SERVICES

Social network service (SNS) – the web-based interaction tool introduced in late 20 th century – has become increasingly popular in modern life. The SNS providers’ capability of launching a ‘killer application’, i.e., an attractive interface that motivates user engagement and stickiness, plays a crucial role in surviving the keen competition in the SNS market, and the development of such a service requires rapid and continuous innovation practice. This study proposes an IDEA Diamond model that aims to help SNS providers effectively develop (through a well-defined process and systemized methods/tools) new services that can meet user needs and deliver exceptional user experience.
