This 16-page white paper discusses electronic marshalling—eliminating “cross-marshalling” to wired discrete and 4-20mA devices—for brownfield and greenfield projects, as well as adding controllers and input/output (I/O) devices can be done with less complexity.
The paper cites late change orders around I/O requirements, more aggressive schedules, sequential execution of projects and new technology learning curves—“the complexity paradox”—as prime examples of how projects have become more complex.
