The U.S. Department of Homeland Security announced a call for proposals in 2005 for a multi-billion-dollar project called Secure Border Initiative (SBInet) to test the ability of technology to control U.S. borders after a succession of failures. What type of structure are they envisioning for the SBInet? Suppose that you were going to conduct a systems engineering study that focused on the U.S. border as a system. (a) Apply systems thinking tothis problem by usingthe environment factors of the SDP to construct a systems hierarchy that shows the major lateral and multilateral systems, subsystems, and metasystems that dene the U.S. border. (b) Would a policy of limiting immigration to the United States be a systemlevel or symptom-level system solution? Explain. (c) Which of the systems that you specied in part (a) would you consider to evolve over time? (d) For each of the evolving systems you identied in part (c), list one symptom-level and one system-levelphenomenon that you think provide evidence that the system is evolving.
