 I'm UI Choi. I'm a partner from Seoul office. I'm in global technology and service practice. Major changes include technical expertise like artificial intelligence, machine learning and big data. They need to have leadership and fellowship to recruit right developers and engineers and also ability for culture shaping. And more local companies try to expand into global markets. Global experience and business acumen are also required capabilities for successful CTO. I actually placed one CTO who worked for Silicon based big tech company who joined local e-commerce company. He drove culture shaping into agile organization and he developed very strong tech team. As more Korean local companies try to expand into global markets, developing tech leadership with global experience and business acumen is very critical. And as more female leaders emerged in the digital space as founder of startup businesses and also female executives at global and local companies are increasing. But the CTO and CIO function roles developing the leadership, especially female leadership is behind. We need to create a culture where tech leaders with global mindset and business acumen can work cross functionally and cross geographically. And also incumbent tech leaders put more focus on developing female talent and the function role of CTO and CIO. At the same time, the female leaders or female talent in their mid career, they need to have a long term sustainable career goal. They can be CTO and CIO and later they can turn into CEO. As a successful CTO profile involves being business savvy and leadership responsibilities. So having business acumen and understanding their business and products and also communication skills with various stakeholders will be very important.
