Overview of the Session:
Modern organisations generate vast amounts of data across finance, operations, tax, customer platforms, and supply chains. The challenge is no longer collecting data — it is transforming it into trusted insight that supports faster decisions, stronger compliance, and operational efficiency.
Data Management, Analytics & AI provide the foundation for organisations to automate processes, improve visibility, reduce risk, and unlock strategic value.
The session will review:
1. AI is transforming decision‑making, but data quality determines trust.As AI adoption accelerates, control over data quality becomes a critical risk‑management responsibility.
2. Why EDA & Data Fundamentals Matter More Than EverExploratory Data Analysis (EDA) is the control framework behind AI‑driven insights.
EDA turns AI from a black box into a controlled, defensible decision tool.3. From Predictions to Accountable DecisionsPredictive analytics explains the “what”; strong data fundamentals explain the “why.”
In regulated environments, trust, explainability, and governance matter as much as accuracy.4. Example of how this looks in a Tax Team environment
