Vodafone Iceland has been using exMon since 2010. Vodafone continuously monitors its data and services, emphasizing customer happiness, revenue leakage, and fraud monitoring.
Their implementation resulted in less revenue leakage and a much shorter billing period.
Recently a case study of Vodafone usage of exMon and its results were published in Audit Analytics and Continuous Audit, an American university textbook in Continuous Auditing by the American Institute of Certified Public Accountants.
You can read all about Vodafone’s usage of exMon here: Audit Analytics Book Vodafone Case Study.
You can download the book for free at the AICPA website: Continuous Assurance & Continuous Control Monitoring.
