Thanks Dean, I was trying to communicate this to him also. I manage
IT/IS/Comms for an Oil company[1] and we have equipment installed at our
refinery and at our drillsites.

IS is a fundamental building block of all our work, and yes it does increse
the cost by a factor of at least 3 and more likely 10 when all the other
costs are taken in to account.
