Adverse events only occur after a chain of events have formed to break through an organization's system defenses. If you are looking to reduce or eliminate adverse events, you must identify what defense mechanisms your organization has designed into its systems and associated working-level processes.

A "ny-fix-fly" philosophy of operation was no longer affordable or tolerable.
