| It is essential for company to complete ERP implementation by using systemic method. In recent years more and more high-level managers are focus on ERP systemic implementation. But how to recongnize these knowledge and how to use it in practice that is a new pop field. Under researching ERP implementation method from reference books and scientific managinze, Hunan LianXin gains a correct implementation method in common.Steel-trade industry is a fund- integration on globe. The local ones have a advantages than demotic in prices and logistics. As a traditional industry, the informationization is starting and acceleration performance. The Hall three dimensions structure is a high efficiency way to help company to finish ERP implementation. Appliance these theorys to ERP, A Hunan local company will be easy to find out key steps and succeed in ERP implementation.The Hall implementation method provides a perfect implementation framework. With main route of Time-dimension, the process divides into senven logic dimensions. There logic dimensions include senven steps, Problem definition, Selecting objectives system, Synthesis,System analysis, System optimization, Decision and Analysis system development. Using these senven steps, The ERP implementation will be on highway. Problem definition brings forward the Time-dimension goal. Abstraction step by step is Selecting objectives system. Synthesis will integrate some facts or theory into ERP Implementation. System analysis is drinking in above steps to analysis. System optimization builds on finding better scheme. Then, the article uses Linear programming and The analytic hierarchy process in Decision. At last Analysis system development will finish Time-dimension's ERP Implementation. Otherwise, it explains the two models on chart with Hall theory. Finally it specifys Knowledge-dimension. All these theory and method are explained by instance which is a Hunan local steel-trade company.Choosing a correct implementation by the own, the company maybe test so many times. In accordance with Hall theory, steel-trade company will solve a lots of ERP implementation problems quickly. With the systemic method development, the informationization of Hunan LianXin will go into a new activity stages. |
