Abstract Due to the development and proliferation of information and communication technologies, people¡¦s daily lives are indispensably relied on these tools. Based on concepts of safety, energy conservation, convenience, and comfort, intelligent buildings¡¦ designs have gradually become the main stream of the present and future architectures. Taiwan introduced the idea of the intelligent building since 1989. With the push of the automatic idea of the building, the security and surveillance systems integrators had become the new popular industry and the competition of the industry is more and more fierce. Understanding the key successful factors objectively is important of making administrative decision to security and surveillance systems integrator managers. In view of this, this research adopts the expert focus group interview and analytic hierarchy process theory. The author interview 10 high-level experts of the security and surveillance systems integrators and 10 customer experts of intelligence building traders to develop a set of the key success factors appraisal procedure to the security and surveillance systems integrators for intelligent buildings. Based on enterprise factor, staffs factor, and products factor, the author calculate the ranks and weights of the criterion and sub-criterion of the key successful factors. This can offer the security and surveillance systems integrator managers for intelligent buildings to make administrative decision. The study chooses three companies as an example to do empirical study, and compares their advantage and performance of the key successful factors. The result of study finds as follows. In criterion, the most important is produce factor, the less is staffs factor, and the end is enterprise factor. In sub-criterion, the most important is staff's professional ability technology, the less are price, products diversification, and customize degree. In ranks and weights, the last are productions separately, organized scale, and popularity and impressions. The conclusion can offer the security and surveillance systems integrator managers for intelligent buildings to make administrative decision.

With the coming of digital times, global competition resulted in every industry expanding their requirements in supply chain integration and enterprise resource planning. The importance of information system integration industries also increases with time. When all kind of industries continues to integrate supply chain and establish cooperative partnerships, trying to exploit cooperation to acquire more competencies in the market, we want to know whether the information system integration industries establish their cooperative relationship. Therefore, our study tried to review the actives and relationship between integrators by the systems integration service process. Through the theory¡¦s guiding, we attend to induce the factors of inter-firm cooperation in system integration industries. We use multiple case study to design our research¡Aand select three cases to study. Semi-structural interview is used to collect needed data to understand the true cooperative relationship between integrators. According to transaction cost theory, resource-base theory and social exchange theory, we propose some theoretical propositions to guiding the real cases analysis. The conclusions not only describe the real cooperation in Taiwan system integration industries, but also induce several factors of cooperative relationship between integrators, including product characteristics, transaction cost, resource, trust and guanxi. Moreover, the transaction cost is the most important element in the cooperative relationship between information system integrators.
