HAPPY BIRTHDAY TULLY!!!
So much of the work of Eliyahu Goldratt’s work provides inspiration to challenge the status quo of your work environment and realise significant productivity and profit improvements in a system. Starting with outlining the steps to to identify and optimise around a bottle neck in “The Goal”,
Goldratt brings to the world additional tools known as his Logical Thinking Process, introduced in more detail in his business novel “Its Not Luck
Goldratt’s Logical Thinking Process provides a framework for navigating complexity, helping us uncover those few, inherently simple root causes that manifest all the undesirable effects of the system at large. When we use logic as a basis for decision- making, the Logical Thinking Process is a powerful ally which helps us, in the first place, understand the difference between
‘necessary condition’ and ‘sufficient cause’ logic. Indeed, one of the most common mistakes of almost every person I have worked with is to assume that what is necessary is, therefore, sufficient.
The evaporating cloud or conflict resolution diagram is an excellent tool for systematically surfacing and challenging conflicts. It forces the user to lay out the perceived logic behind a proposed solution and dig into assumptions that place it in conflict or tension with alternative solutions. Once these assumptions are made clear, solutions that invalidate or “evaporate” the assumptions are then found.
“The Evaporating Clouds method does not strive to reach a compromise solution, rather it concentrates on invalidating the problem itself.” Eliyahu M. Goldratt
The evaporating cloud has five elements: an objective (green), two requirements for achieving that objective (Blue), and two prerequisites for satisfying those requirements (Red). The boxes are highlighted in red with the arrows as these requirements are normally in conflict with one another.
