Writing use cases

Please refer to Basic Use Case Template

My short note is:

(1) Define actors
E.g. "Customer", "Shipping System"

(2) Write down names of scenarios (i.e. use cases) which may include a number of activities
E.g. "Create Account" , "Log In" , "Check Out"

(3) Group the use cases as system boundary which defines the scope of what a system will be.

(4) Use arrows showing which actors are involved in which use cases

Then you can finish a high-level use diagram.
