API 580, Section 5.6.4 outlines situations where "inspection may not be sufficient to manage risks," stating:
"Examples where inspection may not be sufficient... are: a) equipment nearing end of service life." In such scenarios, additional mitigation such as equipment replacement or redesign is often necessary to reduce risk to acceptable levels.

As clearly stated in API 580, Section 7.2:
"The precision of the data should be consistent with the RBI method used. The individual or team should understand the precision of the data needed for the analysis before gathering it." This means qualitative, semi-quantitative, and quantitative approaches may require different levels of data precision.

According to API 580, Section 9.4.3:
"It is important to link the damage mechanism to the most likely resulting failure mode. For example:
a) pitting generally leads to small-hole-sized leaks;
b) stress corrosion cracking can develop into small through-wall cracks or in some cases rupture..." This highlights that identifying the specific failure mode (e.g., leak, rupture) related to the damage mechanism is critical for accurate probability and consequence analysis.
