Business Dynamics & Research was co-founded by Dr. Reginald Tomas Lee in 1994 using cash-based business models he created. An engineer with a passion for business and math, Reginald is a pioneer in debunking the validity of accounting information for managerial purposes. As a replacement, he developed Business Domain Management, a mathematically sound operations and cash business framework that provides significantly more accurate and effective managerial and cash-based data and information than accounting. His work has proven valuable in helping leaders see, understand, and manage their operational and cash performance.


In addition to his work at BDR, Dr. Lee is a professor at Xavier University's Williams College of Business. Previously, he has worked for a number of major global brands including EY, GM, IBM, and Oracle. In addition to teaching business at Xavier, he has also been a professor of industrial engineering, mechanical engineering, and business at other schools, most recently, Miami University's Farmer School of Business.


Dr. Lee is currently the author of four books, Strategic Cost Transformation, Lies, Damned Lies, and Cost AccountingEssentials of Capacity Management, and Explicit Cost Dynamics.  He has three books under contract:​

  • Project Profitability:  How to select, justify, and implement projects to achieve maximum cash ROI,

  • Essentials of Managing Capacity, and

  • Engagement Economics: Planning and Managing Engagements to Improve Cash Profitability

He has also published more than 30 articles in magazines such as APICS, Cincinnati Business Courier, Cost Management, Industrial Engineer, Industrial Management, Journal of Cost Management, Journal of Corporate Accounting & Finance, and Solutions



Reginald has a PhD in mechanical engineering from the University of Dayton
