ISA-18, Part 3 is now available for download. Now is also a perfect time to get all three parts of the standard- all are downloadable and available on the web.

This part of the standard defines activity models of manufacturing operations management that enable an enterprise system to control system integration. The activities defined in this part of the standard are consistent with the Part 1 object models definitions. The modeled activities operate between business planning and logistics functions, defined as the Part 1 Level 4 functions, and the process control functions, defined as the Part 1 Level 2 functions. The scope of Part 3 encompasses: a model of the activities associated with manufacturing operations management, Level 3 functions; and an identification of some of the data exchanged between Level 3 activities.
