The User would undertake all his business functions through ONEi
- i.e. he would not only view screens but also "transact" using
these screens.For instance,by using ONEi,a Salesperson would
be able to respond to customer queries,perform a credit check
(after a subscription request) and activate a connection as one
continuous process,even though multiple systems,both inside and
outside the enterprise,are getting involved.
    
ONEi may be viewed as providing the following key user services:
