About JonahLisa

I've spent the past 30+ years in the TOC consulting and educating field, leading implementations and helping companies deliver unparalleled operational and financial results.
But in 2019 I decided to set out on a different path. Using TOC principles, I now focus on equipping leaders and their teams to uncover the faulty assumptions at the core of their toughest challenges so that they can deliver extraordinary results.

I call it Assumption Hacking.
