The difference between the old version of Production the TOC Way and the new version is:

• The old DOS simulator is replaced with a new Windows one. It is a stand alone software, no need for anything else.
• The simulator scenarios are basically the same.
• Eli Goldratt uses a somewhat different buffers in the new version: the shipping buffer covers the whole production floor from materials to the shipping, and the CCR buffer, which is part of the shipping buffer. there is no assembly buffer (no need for one). Of course, the change forced a substantial change in the text.
• The whole approach to buffer management went through a significant change. Buffer management is presented differently in the new version of the simulator and Eli re-wrote the relevant chapter almost from scratch.
• In the old version the "instructor book" was intended for people with appropriate credentials and they could buy the Student books for their pupils. For now, the instructor and every student must buy his/her own book/CD
• The last difference is the price. When someone wishes to teach he/she does not need to pay royalties. The only requirement is that every student has his/her own book and CD.
