Big data has transformed many businesses, though some companies remain wary of investing heavily in it. To successfully use analytics, companies must follow three steps: source and manage multiple data sources, build advanced analytics models to predict and optimize outcomes, and transform the organization so data and models guide better decisions. Specifically, companies should identify usable existing data and new sources, develop simple yet powerful analytics tools, and train employees to make data-driven decisions. When done right, analytics can optimize performance if grounded in business needs and practical data relationships.
