How Dilek is building a better working world

"Companies aiming to separate their competitors and open to new markets in the digital economy need to evaluate their audit processes appropriately while implementing new technologies. New technologies such as blockchain, artificial intelligence (AI), internet of things (IoT), and robotic process automation (RSO) bring competitive advantages to companies. I believe machine learning will gain more importance especially in the field of ethical control approaches. We shape the business world of the future faster with the synergy that consists of our cooperation with our customers in audit services that constantly change and require expertise in different fields."
