Which method is NOT commonly used to measure crew morale?

Implementing strict rules is not commonly used as a method to measure crew morale. While rules can set the framework for behavior and expectations within a team, they do not provide insight into the emotional and psychological state of the crew. Measuring morale typically requires an understanding of how crew members feel about their work environment, their relationships with each other, and their overall job satisfaction.

Surveys and one-on-one meetings are effective tools for gathering direct feedback from crew members, allowing them to express their thoughts and feelings in a safe space. Observing team interactions can provide additional qualitative insights into how team members engage with one another, which is also critical for assessing morale. In contrast, strict rules may actually hinder open communication and discourage the sharing of concerns, ultimately limiting the ability to accurately gauge morale within the team.
