Legacy applications are often numerous, inflexible, and locally unique, with customized integration that is expensive to maintain. Infrastructure is often inconsistent across facilities with local hardware deployment and support personnel. Further, site IT operations processes may not be industry-standard best practice and are highly susceptible to varying demands from local users and sub-optimized from an enterprise perspective. Most plant-level IT personnel are inwardly focused on their own site and not exposed to the rest of the industry.
