As systems improve we expect that the certainty of meeting objectives increases.
Instead, what often happens is that systems become more complex over time which results in the emergence of new uncertainty which leads to increased risk.
It is at this point that systems become unresponsive and are no longer able meet their objectives. Remediation is necessary to bring the system under control. However, this can be too slow and often too late to prevent future consequences.
This is one of the reasons why you need to be proactive which means:
anticipate, plan and act to prevent these conditions before they happen.
