Most processes operate in the context of an existing site in
which a number of processes are linked to the same utility
system. The utility systems of most sites have evolved
over a period of many years without fundamental questions
being addressed as to the design and operation of the utility
system. The picture is complicated by individual production
processes on a site belonging to different business areas,
each assessing investment proposals independently from
one another and each planning for the future in terms
of their own business. Yet, the efficiency of the site
infrastructure and the required investment is of strategic
importance and must be considered across the site as a
whole, even if this crosses the boundaries of different
business areas.
