MES is what you make it. Realizing the true potential of MES requires shifting focus from trying to define where anything fits in the categories, to looking at what is needed to maximize production value for the end user.
Ever since the MESA created the first ISA-95 model, MESA and the industry in general have acknowledged that the boundaries between the different systems which co-exist in a manufacturing company are fluid, not rigid. When looking at the barriers between the ERP and MES software, for example, there is a clear overlap among many functions, such as planning, order control, human resources (HR), and maintenance management, to name a few.
This white paper shows that achieving optimal productivity requires a mix of functions performed selectively by either the ERP or the MES software.
