Eli Schragenheim is also known for his own software simulators and management games designed to experience the thinking and potential of the Theory of Constraints (TOC) in complex environments.

He is the author of several books on various aspects of management. His first book Management Dilemmas (1998) showed a variety of problematic situations in management and the rigorous analysis leading to the right solution. Next he collaborated with William H. Dettmer in writing Manufacturing at Warp Speed. In this book the new concept of Simplified-DBR, now a key concept in production planning according to TOC, was introduced. He also collaborated with Carol A. Ptak on ERP, Tools, Techniques, and Applications for Integrating the Supply Chain, and with Dr. Goldratt and Carol Ptak on Necessary But Not Sufficient. In 2009 his book Supply Chain Management at Warp Speed, with William H. Dettmer and Wayne Patterson was published. The new book contains much of the new developments of TOC in operations in the last 10 years. He also contributed two chapters for the Theory of Constraints Handbook, edited by Cox and Schleier published in 2010 by McGraw-Hill. In his last book Throughput Economics, with Henry Camp and Rocco Surace, Eli takes Goldratt’s Throughput Accounting and develops it further, making it a practical tool to make hard decisions that involve uncertainty and only partial hard information that is based on data.
