He has designed systems for Banking, Brokerage, Medical, Insurance, Rental, and Pesticide businesses. While these may appear wildly different, they all share two common themes: First, one must learn what is meant by the business data, especially when implementing a company’s early systems, and second, one must learn the endless cycle of how that data transforms the business and is itself transformed by the business. For the past 25 years he has managed the ECM-based Electronic Medical Record at Memorial Sloan Kettering Cancer Center in New York City. He is a frequent lecturer and mentor on Content Management.
