Design And Realization Of Flexible ERP System Based On Software Reused

The mutative requirements of ERP is an important factor of the failure of ERP system development. Extreme Program is a kind of lightest software developing method. Its usual method is incremental iterative. XP can make the developer coincidence with the customs' requirement more efficiently. XP has its limits. It only suits to small develop group. Layered XP is put forwarded to drive off this problem. Through this the large-scale and complex software can be divided into separated small topics. Each small problem can be realized by traditional XP team with XP's rules and practices. Not all of the practices of traditional XP can be adopted in large-scale and complex software development. The practices must be tailored for layered XP.Patterns are the summarization of the solutions of the similar software problems. Using patterns in the more scales XP shows that it can both utilize the advantages of patterns and the XP. The system would be steady and easy to maintenance.The ERP systems in the same vocation are similar. When developing the ERP system, common models are defined and layered XP adopted to realize them. This can increase the ratio of software reused and enhance the system to handle the variety of requirement. The system made up of tested models is steady and easy to maintenance.
