Look here for a great article by Einar Nymoen of Telenor. He explains how the Telenor Revenue Assurance Program (TRAP) has adopted strategic measures for revenue assurance across the Telenor group. These measures include a KPI for revenue coverage and the TMF’s Revenue Assurance Maturity Model.
Programs like Einar’s are proof that systematic modeling of the performance and evolution of revenue assurance is not just talk and theory – it is industry best practice.
