We are talking about the word as it applies to day to day IT operations.
Operational resilience is the organization’s ability to adapt to risk that affects its core operational capacities.[i]
This doesn't mean perfection, that you are so well protected that you can ever fail. While that level of protection is necessary in some places it would be over kill for most. What it does mean is that the organization responds in an appropriate way and core operations continue as planned.
How much is enough for your organization? Was that a RISK decision or a Budget decision?
With Resiliency Maturity Indicators in hand, it can be an informed decision!
