The biggest impediment to meeting the
challenges above is the general inflexibility
of aerospace manufacturing systems. 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.
Business information and intelligence suffer
from delayed and inaccurate plant floor data
with inconsistent definitions that prevent
comparisons across facilities and limited
analytical and "drill-down" capabilities.
Manufacturing execution systems (MES) are a
key enabler for best-in-class manufacturing
operations excellence. Successful
manufacturing organizations recognize that
MES is the third leg of critical enterprise
systems, including enterprise resource planning
(ERP) and product lifecycle management (PLM).
But in the past, MES solutions have frequently
overpromised and underdelivered as deployed
