The co-founders of Data Culture, Gabi Steele and Leah Weiss, emphasize that a data-driven culture is essential for companies to succeed. They suggest investing in the domain expertise of data people, sharing business challenges with them, and brainstorming solutions together. To support a data-driven culture, they recommend resisting tensions between business analysts and data analysts, investing in ambassadors and building a data community, embracing inclusivity, and focusing on diversity within the team. By fostering transparency and meaningful connections across both sides of a company, a data-driven culture can drive better outcomes and help organizations reach new heights of success.
