Q:

What is the general/typical order of usage of UML diagrams during development? 

I want to know the order of UML diagrams.  I need to know when I develop new software which UML diagram to use first and which second (and so on) thanks. 

A:

This is not defined in the UML standard.  UML is a notation not a software development method.  You need to choose first a development method that uses the UML notation and then the method will tell you in what order you should define the different UML diagrams.
