In this podcast episode, Mark Eltsefon, a senior data scientist and experimentation evangelist, discusses building an experimentation culture in different companies. He shares his journey from starting as a software developer to becoming passionate about data science and experimentation. He contrasts the experimentation culture at TikTok, where data-driven decisions were central and democratization was encouraged, with his current role at an e-commerce company specializing in print-on-demand. He emphasizes the importance of educating stakeholders about data-driven decision-making, and he highlights the need for strong experimentation infrastructure and high-quality hypothesis testing. He believes that while democratization is valuable, it's important to balance it with maintaining the quality of ideas and statistical rigor.
