"Clearly revenue assurance has greatly increased in scope over the past few years. Revenue assurance professionals are working less on “leakage” and more on “top line revenue delivery” as we get better at the fundamentals of our craft. The skills and knowledge developed while securing revenue streams is not the end of the value delivered, but only the beginning. By leveraging, good core understanding of telco technologies, operations and revenue management activities, revenue assurance professionals are expanding and applying their knowledge in a myriad of other arenas." Rob Mattison discusses the specializations now evolving in the revenue assurance field.
