The practice of business is changing. Due to increasing desktop computing power and huge amounts of data amassed by companies, business decisions are becoming increasingly based on data. This holds in many sectors, including Internet marketing and retailing where the only interaction with the customer is in digital form. While managers perform other tasks, their decision-making determines which enterprises flourish and prosper and which wither and die. It is very difficult to recover from bad decisions. This course aims at conveying some core principles of business analytics. This course is very hands-on and emphasis will be placed on solving real business cases, using real data via spreadsheet-enabled models. The objectives of this course are to try to help students improve modeling and data driven decision making and decision analysis skills, and to expose students, as future analysts/managers, to some of the new tools and ideas that will be helping make decisions in the twenty-first century.
