Rather than rush to judgement I would need more information to answer the question.
For example most manuals have verbage that allows a captain to deviate from procedure for unusual circumstances. This is separate from emergency authority.
So a pilot may brief a deviation of some sort due to unique ramp conditions, etc. That's okay, and, in fact is not a deviation from standards.
Skipping certain elements for convenience is intentional noncompliance.
What happened?
