In this talk, we will explore how Nationwide Building Society are empowering colleagues at all level with access to data, metrics and insights which support a culture of data-led decision making, continuous improvement, and learning. We will share the journey of how we unlocked measurability of quality, flow, and value. What patterns and antipatterns we observed, and how we pivoted. How we set up and ran our experiments, engaged colleagues, built our self-serve dashboard product from scratch and reached an active customer base of 1,200+ colleagues at all level in 2 years.
