We have already observed as the constitution of a Virtual Warehouse demands the sharing of warehouse infrastructures.
Any shape of sharing demands, but, the passage of some powers (decisional and economic) from the single enterprises to a governmental authority of the entire group.
In order to plan and to manage a district net it is necessary that two conditions are come true:

• that a strategic agency exists that cargo to conceive and to realize this plan is made,
• that the net is put in condition of:

1. to control and to manage the net processes;
2. to shape, to select, and to hold assets the multiple logons between inner organizational units and external enterprises (net logons);
3. to develop together: a hierarchical structure, a market, an informative system, a logistic system, a system of communication, a culture, a political system;
4. to develop a system of government ³⁹ .

The several circumstances that have carried to the phase of recess of these years, have taught to us as not always the innovation finds fertile land around to if.
Often in fact, permangono some circumstances in which it is too much legacies to hierarchical relations of power are to the inside of the company, than between several the inner actors to the supply chain.
An optical of short period, capacity ahead from logic of the survival year for year, badly is conciliated with an organizational innovation like that one of the Virtual Warehouse.
The same thing happens in a generalized manner, for all the organizational innovations, in which it comes underrated the necessity of an approach, programmatico of along period, and integrated between more partner of the Supply Chain with it objects to you common, for the attainment of one more strong competitiveness than it arranges.
In a market in which the competition it goes progressively increasing itself, it becomes of fundamental importance the innovation.
Unfortunately the cases are not rare in which today, entire industrial districts, or other agglomerations above all in the manifacturing field are looked at, in serious difficulty in front of the been left over one of the competitiveness of production in other underdeveloped nations, like China.
E' in these cases that an innovation as the Virtual Warehouse can play a fundamental role for the competitiveness of cost of the arrange-district.
More in a generalized manner, it goes felt the necessity to join the efforts, since, even if the advantages deriving from localization go slowly flattening because of the development of the computer science, sussiste technologies anchor cospicuo a patrimony of acquaintances that can be amplified.
The Information and Communication Technology, cross and delight of traditional entities like the districts, can constitute therefore, a resource key for the sharing of these acquaintances, through instruments advances you of management of the Supply Chain, like the Corporate Portals or, more better still the systems than ERP, of which I have already spoken in the previous pages.
The idea of Virtual Warehouse, therefore like all the of outsourcing procedural, or better than outsourcing administrative, involves the renunciation from part of the entrepreneur of part of its sovereignty.
This happens difficultly in the systems in which it is stretched to conserve a rigid and hierarchical organization, founded on force ratios with the own suppliers and/or customers, than does not offer space to the collaboration.
a closed entrepreneurial behavior of this type is most times synonymous of insufficient abilities, and a counter-productive optical too much tied to the result of short period.
