Abstract:Taking advantages of the advanced information technology, more and more construction businesses begin to adopt the large scale information system, such as web-based project management system, Enterprise resource planning (ERP), supply chain management (SCM), electronic knowledge management (eKM) and so on, to improve the management efficiency and productivity. However, it seems there is no effective model for evaluating and implementing an e-Enterprise. A survey of computerization in Taiwan construction contractors shows that on account of lacking the information technology support, the traditional Nolan and technology transfer Model cannot provide a good suggestion in the process of e-Enterprises. A Three-Stage-Model of e-Enterprise, which based on the information technology, will be proposed in this paper. This model can not only evaluate but also implement an e-Enterprise. This paper also discusses about the e-Enterprise's case of Taiwan construction contractors , and give some suggestions for their e-enterprises process.
