The telecom industry has witnessed a sea change in the last few years, with customers demanding more flexibility and greater experience quality than ever before. Services need to be delivered in realtime, instead of days or weeks. Adopting a digitalfirst and self-service ready support model is imperative but this is out of sync with the existing tightly coupled, non-scalable monolithic architecture. With customers calling for zero touch integration across the entire lifecycle, from ordering and activation to billing and support, telcos cannot hold onto legacy systems. Simply put, an entire refresh is required including infrastructure, customer services, as well as operational and business support systems.
