IPA: /nɒn.kəmˈplaɪ.əns/
KK: /nɑnˈkəmˌplaɪəns/
The act of not following rules or regulations that are required.

Noncompliance → It is formed from "non-" (meaning not) and "compliance" (from Latin "compliance", from "complere", meaning to fulfill or complete). The word refers to the state of not fulfilling or adhering to a requirement or standard.
Think of 'not' ('non-') following the act of 'fulfilling' ('compliance') — that's why noncompliance means not fulfilling a requirement.
