Like many CSPs, Chunghwa Telecom (CHT) has embarked on a digital transformation journey to not only adapt to new market realities that call for maximum flexibility and agility but also to become even more relevant and valuable from the customer’s perspective. Working together with Ericsson, CHT leveraged TM Forum’s Open Digital Framework to transform its OSS/BSS stacks and develop an automation ecosystem to enrich its 5G supply chain. This has borne fruit, particularly in the healthcare sector, with 5G remote medical and healthcare services helping Taiwan cope with the COVID-19 pandemic. As long-term members of TM Forum, CHT and Ericsson tapped the TM Forum Open Digital Architecture (ODA) as its overarching automation design guide for operations automation, as well as inspiration to become a digital ecosystem enabler. The integration was also strengthened by leveraging the Ericsson portfolio in facilitating autonomous operation. The building blocks collaborated between CHT and Ericsson constitute an adaptable and intelligible framework - spanning from the capabilities of service creation, service ordering, service orchestration to service assurance with a complete end-to-end perspective. CHT’s digital transformation hasn't been limited to network operations. The telco has also boosted its execution capability not only by cultivating IT, CT, and OT talents to enrich its OSS/BSS, network, and operations but also by incentivizing a collaborative culture with Agile DevSecOps methodologies and processes to deliver faster, high-quality services. All of this provides the foundation for CHT’s strategy to create customer-centric value by becoming the leader of “Smart Life” and positioning itself as the enabler of the digital economy across Taiwan.
