The market for manufacturing execution systems/manufacturing operations management (MES/MOM) implementation services is more complex, in technological terms, than that for traditional enterprise system integration services. Compared with implementations of other enterprise applications, MES/MOM implementations tend to vary from industry to industry and from company to company. In some cases, they also vary from plant to plant. This market represents the “last mile” of IT, where the combination of flexible manufacturing processes and the proliferation of automation devices, after decades of diverse technological development, defies standardization. This market provides buyers with many different services with which to accomplish the diverse tasks that are involved in MES/MOM initiatives and that are often absent from IT organizations.
