Today's telecommunication operators worldwide need to confront changes in both their business and operational environment. Such changes significantly affect the operators' daily life and quick adaptation is key for them to keep following competition and increase profitability. On the one hand, the services landscape has considerably altered. New types of services have come to the foreground and the service model is far deviating from the rather obsolete model of services with long lifespan, like simple voice, which used to contribute the most to the operators' revenues. This dynamicity significantly strains processes associated with the efficient service delivery to the customers.
