Three modules, one data model
Each module works on its own and gets better with the others. All three read and write the same records, so there is nothing to synchronise and no overnight batch to wait for.
How they fit together
Planning decides what to make and when. Inventory knows what is on hand, where, and in which lot. Analytics reads both and turns them into the reports the plant manager, the finance team and the board each need, from the same figures.
