Business intelligence technologies provide finance departments with historical, current, and predictive views of business operations based on integrated data from across the organization. This allows finance to move beyond reporting and into advising the business by revealing trends, patterns, and insights. For example, AT&T Mobility's finance department leverages a Teradata enterprise data warehouse to calculate the profitability of 80 million subscribers daily and identify any subscribers who churned so they can work to win them back. Implementing BI requires getting sponsorship, understanding needs, building partnerships, standardizing data, and delivering self-service tools and timely detailed data to support strategic financial analysis and decision making.
