In the last two decades Telecommunication sector has shown maximum changes and immense potential to change the global business scenario by leaps and bounds, with the introduction of 5G/4G technology, edge computing, cloud technology, IOT, Automation & AI/ML etc. Earlier telecom sector was mostly for the voice and text, but these new technologies bring new user scenarios both for the end customer as well as for the enterprise users and new business models have been developed. The new service mantra is what value can be delivered to the customer; how the newer and innovative services can be offered which can be customizable according to the need to get the customer positive approval. The research studies are done based on the Telecom Service Delivery Area and what are the different challenges the Telecom Service Providers are facing when they talk about the digital transformation and use of newer technologies like Artificial Intelligence and/or Machine Learning. As this is a collection of different research papers so the contents are different but somehow coherent. The contents talk about how the organization should carefully take the steps to get the proper buy-in from their employees to make the initiatives successful and can have a successful long run as per their competitiveness. These are vastly covering the areas like having the customer model to customer satisfactions model, data operating model for organization to have the proper data analytics, organizations' initiatives to successful transformation and transition, use AI/ML etc. Although this is based on the Telecom sector, but the nuances can be extrapolated to other types of industries as well.
