The invitation from TOCICO (Theory of Constraints International Certification Organization) was originated by an article that Eduardo Moura wrote in 2004. In it, the consultant explained the advantages of integrating TOC (Theory of Constraints), Lean Production System, Six Sigma and BMP (Business Management by Processes). For those of you who aren't familiar with TOCICO, they're a global not-for-profit certification organization for TOC practitioners, consultants and academics to develop and administer certification standards, and facilitate the exchange of latest developments.
