What signs are considered critical, and which are not, when assessing a system or component?

Critical signs of a system or component are those that directly affect its operability, safety, or stability. For example:

• Complete service unavailability (downtime).
• Data loss or integrity violation.
• Security vulnerabilities allowing unauthorized access.
• Critical errors leading to failures.

Non-critical signs are those that do not affect the main operation but can degrade experience or efficiency:

• Response slowdown without complete failure.
• Logical errors that do not lead to failures.
• Non-critical warnings and errors in logs.

When assessing, it is important to prioritize problem resolution, addressing critical issues first and then less important ones.
