Eliyahu Goldratt introduced an integrated problem-solving tool set loosely known as the “Theory of Constraints” (TOC) in the early 1990s. For those people who are already familiar with the TOC methods, this chapter is intended to show how TRIZ and TOC integrate very naturally. For those who would like more information on TOC, we suggest Goldratt’s books,1-3 H. William Dettmer’s books,4,5 and the articles in The TRIZ Journal by Domb and Dettmer6 and Ed Moura.7
