    It's okay to be 5% wrong, but 95% right…[with the time you free up] you will make up much more value than trying to optimize the last 5%.

    The role of Chief Data Analytics Officer goes way beyond the technology. It's 10 percent about technology, 20 percent about data, but actually 70 percent about transformation and adoption.

    Generative AI is a game changer for efficiency and helping us focus on human creativity.
