Eli Goldratt: !There are two pillars to the Theory of Constraints.
© 2014 goldratt-toc Ltd China | England | Italy | Poland | Scotland GTL3
One pillar is the starting assumption of all the hard sciences, which is that
in all real-life systems there is inherent simplicity.
If you can just find that inherent simplicity, you can manage, control and improve the system.

The other pillar is“that people are not stupid.”
“and people are good.”

The injections (the new things needed to create the solution) are normally not trivial items. The PrT is used to identify smaller logically sequenced steps to put the Injections in place.

The Transition Tree is used to recommend the actions needed to reach an IO; a step in the PrT. The backbone of the TrT describes the change that is expected as the actions are taken.
