Cathy Tanimura discusses building a data foundation for analytics excellence at Okta. She outlines finding problems to solve by researching high impact issues and engaging business partners. For a proof of concept, one should find available data, use simple tools, build something, and get feedback. When picking technology, consider requirements, educate on options, and present small, medium, large cost choices. Expect timelines and budgets to increase from initial plans. Building a team requires data, engineering, and science skills at different stages. Partners and executive champions are key to spreading awareness of the work. The end goal is using data and analytics to save time, increase revenue, and focus efforts.
