Do you think that a same style of command can be effective in a given environment and ineffective in another? Why?

Yes, it depends on how long it will take for a certain clearance request to be cleared, for example, in a government institution, an ordinary request might take up to a week or more, because a director is either busy or in a vacation. 

In a private corporation for example, a person in a vacation will be immediately substituted by another person with the same level of power, thus operate within the same scope. 

Thats true we cannot adopt the same agreement /structure everywhere. We need to apply different structures. 

Thanks for invitation, 

Yes of course, as it depends of the factor / factors that are governed or control the business's environment in case by case basis.

Thanks 

I fully agree with my colleague Abdulrhmans answer
