Since we can
estimate the costs associated with each ECM accurately, we can develop top level
"go-no-go" analysis. In this manner, we can focus on the ECM's that make
the most economic sense, while relegating the less cost effective measures to a footnote
in the design intent document. Rather than shotgun a system design with every
imaginable ECM, we start out with a shotgun during the preliminary design phase, and end
up with a laser scalpel in the construction document phase.
