Exploring the Dynamics of a Centralized Data Team

As a data leader, one of your most crucial decisions is how to structure your team. Should you centralize for consistency, embed for domain expertise, or find a middle ground?

In this episode of More than Numbers Live, Ollie Hughes sits down with Lydia Monnington, Data Science Lead at Google DeepMind, to explore this perennial challenge facing data organizations of all sizes.

With experience leading data teams at Meta, Ocado, Stuart, and now Google DeepMind, Lydia brings practical insights on what works (and what doesn't) when organizing data professionals. She breaks down the evolution of data team structures and provides actionable advice on making the most of your talent—regardless of your current setup.

In our conversation, Lydia shares:

• The natural evolution from centralized to embedded teams and the pitfalls to avoid in each model
• Why a matrix/hybrid model often delivers the best results and how to successfully implement it
• Practical approaches to managing specialized roles like data engineers, analysts and scientists
• The critical importance of establishing strong relationships between your data team and business stakeholders

Whether you're managing a small centralized team, leading embedded analysts, or navigating the complexities of a hybrid structure, this episode offers valuable frameworks to make your data organization more effective.
