Some academics in the [[Operations Research]] and [[Management Science]] communities claim {{Who|date=December 2007}} that the TOC founder, [[Eliyahu M. Goldratt]], and some of his followers display a strong guru-like and sales pitch attitude that it is not compatible with the spirit of true scientific investigation.{{Fact|date=December 2007}}

In particular, people claim{{Fact|date=November 2007}} Goldratt's books fail to acknowledge that TOC borrows from more than 40 years of previous Management Science research and practice, particularly from [[Program Evaluation and Review Technique|PERT]]/[[Critical path method|CPM]] and [[Just-in-time (business)|JIT]]. A rebuttal to these crticisms is offered in Goldratt's "What is the Theory of Constraints and How Should it be Implemented?", and in his audio audio program, "Beyond The Goal". In these, Goldratt discusses the history of disciplinary sciences, compares the strengths and weaknesses of the various disciplines, and acknowledges the sources of information and inspiration for the Thinking Processes and Critical Chain methodologies.

D. Trietsch from University of Auckland argues that DBR methodology is inferior to competing methodologies. <ref>http://iospress.metapress.com/openurl.asp?genre=article&issn=0167-2533&volume=24&issue=1&spage=105 D.
