Conference Name:International Conference on Management and Service Science, MASS 2011. Conference Address: Wuhan, China. Time:August 12, 2011 - August 14, 2011.IEEE Wuhan Section; Wuhan University; Nankai University; Fuzhou University; University of Science and Technology BeijingIn view of the features of enterprise application software (EAS), this paper researches on its project implementation model combining software development process and software project management. With existing software development theories and tools, we analyze the implementation of EAS project from three dimensions (Process, Management and Technique) and put forward the 3-dimension model and each dimension's core concepts and constitution. This model establishes system model and knowledge structure for implementing EAS and can be used to guide project management. At last, the paper indicates that the model is effective and reasonable. ? 2011 IEEE
