The figure centers them is other the provider, that is that enterprise that is engaged to supply the assets and the services demands, in the times wishes you to the enterprise that has external the activity.
Generally the provider it has to disposition a basket of enterprises to which to make reference in order to obtain the assets and the services to supply; being able to count on a large amount of coming from demands from various customers, the vendor it can generate savings of scale, being able to offer therefore produced and services of optimal quality to favorable prices.
