a computer - based analysis of an enterprise computer system is utilized to remove bottlenecks that cause the enterprise computer system to operate in a non - optimal or risky manner . contents of e - mails are examined to identify bottlenecks in the enterprise computer system . upon identifying the bottlenecks , the enterprise computer system is simulated , and simulations of replacement components , which the computer - based analysis has deemed appropriate for curing the bottlenecks , are installed in the simulated system . if the computer simulation with the replacement components cures the bottlenecks and causes no new problems for the enterprise computer system , then corresponding actual replacement components are installed in the enterprise computer system .
