Report Complicated or complex? in Contracting Workforce Posted August 17, 2021 Its a bit of a linguistic game, of course, but my vote is - Complicated, not complex. The Federal acquisition system has bazillions of parts, so its pretty complicated, but it doesn't have those properties I associate with complexity. It doesn't have emergent behavior- like there isn't anything about it that is more than the sum of its parts. At least, not that I observe.
