egrated into the entire supply chain. ( Avraham Shtub ,1999,p239 )

In conclusion, ERP system enables many advanced management thoughts into computer software systems which can be implemented and applied in the reality by the development and adoption of IT techniques in incredible speed.

The relationship between ERP system and an enterprise & ERP’s role in the enterprise.

ERP is based on the advanced and effective management thoughts and methods. It makes use of new management mode to rebuild old one in one enterprise. The relationship between ERP and the enterprise is supplementary to each other.

1．The implementation of ERP system is the revolution of an enterprise from all orientations.

　Conductors of an enterprise should be trainees at first. The second comes others who are responsible to carry out and implement. It should be motivated activities for conductors, the leaders’ level and stuff to regulate the management of the undertaking and other relevant sectors. Therefore, it helps modern management consciousness being planted into enterprise and becomes one part of company culture finally.

2．The manage mental level should reach the common sense on the ERP implementation
　　
It is important to notice and exercise fundamental works in the matters of one enterprise management. Applications and software suppliers can not offer any kinds of services on this, only can be obtained by hard-workings of the company itself gradually. The implementation of ERP has been regarded as ‘The Engineering of CEO’, which indicates that the company’s decision maker plays a special role during the implementation stage. ERP is the system on management which leads and supervises the entire enterprise. It would have not been effective if the CEO has not approved and authorized the system.

3．The investment of ERP system is the systematical engineering
　　
Compared with the investment and outcome of capital asserts and equipment, the investment of ERP system could not be redounded soon. The ERP system adoption is the systematical engineering process which needs time to realize benefits step by step. What it carries out is the thought of enterprise management which is the red line of the undertaking management. It acts and creates profits in the long turn; moreover, it can achieve benefits and profits form the result of effective management more and more (Chen Jian, 2002 August 7 ).

Furthermore, the investment of ERP system is nothing done once and for ever. Due to the fast developed technologies, the further implementation the system has been done, the tighter resources the company would be aware of. Therefore, the annually investment will be required accordingly in order that the system could ensure for operating healthily.
　　
4．The application of ERP system requires supports of inter-disciplinary talents of the company

The personnel not only have a good knowledge of computer science, but also understand enterprises management. It takes times and procedures to train the inter-disciplinary talents. Managers of enterprises should respect them as a big fortune which has been deserved difficultly. These talents would be the forerunners who will lead companies to implement ERP system into organizations ( Daniel Edmund O'Leary,2002,p92).

In the age of information, ERP system has played significant role in the enterprise nowadays. Therefore, ERP is generally regarded as:
 The bridge linking all departments and sectors
 The core of the enterprise
 The brain controlling daily operations of the enterprise
 The linkage between supply chains of different enterprise.
 The key to succeed in furious competitions with other undertakings
   
But I have to say is the ERP is not a management; it can not replace the real management. The ERP can’t resolve the management problem of the business enterprise. The management problem of the business enterprise only is resolved by enterprise governor themselves. The ERP just is a kind of tool for help the enterprise governor manages the enterprise.
Case study
A properly implemented ERP system can result in significant cost savings and increased efficiency.
