TOCICO — the Theory of Constraints International Certification Organization — was founded in 2001 to professionalize TOC practice and create a community of practitioners independent of any single commercial entity. It represents an important step in the institutionalization of theory-of-constraints as a discipline with recognized standards rather than a proprietary methodology owned by a single firm.
TOCICO maintains the TOCICO Dictionary, a canonical reference for TOC terminology, and the TOCICO Body of Knowledge, which defines competency areas for certification. This standardization effort has helped reduce the terminological drift that tends to fragment management methodologies as they spread across consultants and organizations. Areas covered include five-focusing-steps, thinking-processes, drum-buffer-rope, critical-chain-project-management, buffer-management, and throughput-accounting.
The organization hosts an annual international conference that serves as the primary gathering point for TOC researchers, practitioners, and educators. The conference has been a venue for presenting new applications of TOC in healthcare, software development, education, government, and supply chain management.
Crucially, TOCICO has continued operating through the post-goldratt-continuation era following Goldratt's death in 2011. Its existence as an independent body means that TOC certification and knowledge development did not collapse with the loss of the field's founder. The founding-of-tocico event marked a deliberate effort to ensure that TOC's future would not depend entirely on any single person or organization.
