Importance	Essential	Desirable
Priority	High	Medium
Requirement	Mandatory	Recommended
Compliance	Non-negotiable	Flexible

Definition

Must Be and Should Be are two terms that are often used interchangeably, but they actually have distinct meanings. Must Be implies a requirement or necessity, indicating that something is mandatory or essential. On the other hand, Should Be suggests a recommendation or suggestion, indicating that something is advisable or preferred.

Usage

Must Be is typically used when there is a rule, law, or regulation that must be followed. For example, "All employees must be vaccinated before returning to work." Should Be, on the other hand, is used when there is a best practice or guideline to be followed. For example, "Employees should be punctual for meetings."

Implications

When something Must Be done, there are consequences for not complying with the requirement. Failure to meet a Must Be requirement can result in penalties, disciplinary action, or other negative outcomes. Should Be, on the other hand, carries less weight and is more about encouraging desirable behavior rather than enforcing it.

Certainty

Must Be statements are more definitive and absolute, leaving little room for interpretation or debate. They leave no doubt about what is expected or required. Should Be statements, on the other hand, are more open to interpretation and allow for some flexibility in how they are implemented.

Authority

Must Be statements often come from a higher authority, such as a government agency, regulatory body, or employer. They are non-negotiable and must be followed to comply with the law or organizational policies. Should Be statements, on the other hand, are often based on best practices or recommendations from experts in a particular field.

Examples

• Must Be: All passengers must be seated with their seatbelts fastened during takeoff and landing.
• Should Be: Passengers should be courteous to flight attendants and fellow passengers.

Conclusion

While both Must Be and Should Be convey a sense of obligation or expectation, they differ in terms of their level of importance, authority, and certainty. Must Be is more rigid and mandatory, while Should Be is more flexible and advisory. Understanding the distinctions between these two terms can help clarify expectations and responsibilities in various contexts.
