Gijs is a founding partner of the International House of TOC (iHOT), an organization dedicated to education and implementation of the Theory of Constraints. He is working closely together a number of other TOC Experts for solution development, education and implementation.
Gijs became aware of TOC some 35 years ago, when Eli Goldratt introduced his first business novel The Goal. Gijs has achieved his MSc TOC Healthcare Management at the Nottingham Trent University in the UK.
Gijs, a TOC educated and trained specialist in patient-flow, is playing a leading role in the introduction of the Theory of Constraints into the healthcare system in The Netherlands. Gijs has worked on many TOC implementations, including Maasstad Ziekenhuis (The Netherlands), St Antonius Hospital (The Netherlands), Nij Smellinghe (The Netherlands), Barking Havering and Redbridge University Hospitals NHS Trust (UK) and University Hospitals Coventry and Warwickshire NHS Trust (UK).
His newest development is the introduction of TOC in service industry. Together with 3 of his colleagues he wrote two books on that subject: The Servicefactory and The Projectfactory (only available in Dutch at this moment), which describe the general TOC solution for service companies and the way to implement it.
