Dr. Eli Goldratt (Creator of TOC) was an educator, author, scientist, philosopher, and business leader. But he was, first and foremost, a thinker who provoked others to think. With the mindset of a scientist, he truly believed that “all complex systems are governed by inherent simplicity” and “all conflicts can be eliminated…if we can find the erroneous assumptions”.

TOC Thinking Processes provide a step-by-step methodology to surface the limiting assumptions. Once these deep-rooted assumptions are surfaced and invalidated, it enables us to unlock huge hidden potential. The Evaporating Cloud (Cloud) or Conflict Diagram, first introduced in Dr. Goldratt’s book Its Not Luck (Goal II) is the most commonly used TOC Thinking Processes tool. It is used to articulate any problem as a conflict, and find the erroneous limiting assumptions.
