This paper examines the human aspects of innovation management in an organization by modeling a knowledge sharing relationship model, which includes the following factors, culture, trust and informal network. It is expected to identify an innovation performance by the model in the organization for ensuring knowledge sharing relationships. A survey questionnaire were distributed to measure independent variables (trust , informal network, culture and knowledge sharing) and patent count data from two databanks (Taiwan Intellectual Property Office, TIPO and Taiwan Electronic Journal, TEJ) were used to measure the innovation performance. The overall sample consists of 276 high-tech firms in Taiwan operating during the period 2002 to 2006 years from Taiwan Stock Exchange (TSE). The research framework developed in this study was tested amongst managers of 100 high tech industry firms in Taiwan to examine if in the firms can make opportunity to share tacit knowledge with their employees and then influence their organizational innovation performance.
