This strategy allows realizing scale economies and on the whole, reducing all the costs but communication becomes more and more complex, and finding a standard dialect is essential. Moreover, the number of enterprize actors increase (customers, stakeholders, shareholders, all the employees of each department...) and it is important to create a communication link between all these people. The constant development of the technology and the enhancement of the competiton on the market 'has created', increasingly demanding customers. That is why firms have to constantly find solutions to satisfy them. In order to achieve this objective, companies have to synchronize information between the back and the front office using new technologies. E-Business is a good process. Indeed, it is the integration of the IT and communication tools in business applications which improve the fluidity, the rapidity and the understanding of information.
