To strengthen competitiveness in global financial services, it is essential to shift from regionally siloed IT organizations to a global model that achieves enterprise-wide optimization. At the Nomura Group, we have advanced efforts centered on standardizing IT infrastructure, while building private and public cloud platforms and establishing global operations and in-house development capabilities. Through standardization, in-house development, and automation, we are enhancing agility and cost competitiveness and applying these gains to the adoption of new technologies, as well as to the use of AI, data, and more advanced cybersecurity measures. In addition, we are promoting organizational transformation by fostering a mindset that supports growth and advancing workstyle reform. We will introduce how we have carried out IT transformation as a management issue, along with the practices and outcomes achieved.
