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]]. SuchA criticsrebuttal wouldto dothese wellcrticisms tois readoffered in Goldratt's "What is the Theory of Constraints and How Should it be Implemented?", and listenin tohis theaudio audio program, "Beyond The Goal",. bothIn by Dr.these, Goldratt, in which he discusses the history of disciplinary sciences, compares the strengths and weaknesses of the various disciplines, and acknowledges the many 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.

TheIt criticismis failsnot toclear that this criticism acknowledgeacknowledges that the earlier approaches did not explain the Theory nor did they lead to the level of results that are routinely achieved through TOC. Dr Goldratt's hasposition alwaysis saidthat the methodologies should not compete; they should work together to create better results and generate and disseminate more knowledge. Moreover, it is arguable that earlier approaches were often centered around: continuous mass production rather than discrete batch production, assumptions of infinite capacity rather than finite capacity, and many localised but ineffective safety buffers rather than one or a few critical global safety buffers. Perhaps most importantly TOC is argued to be "portable" over a wide range of logistical problems that were previously intractable.
