Others have already responded with sources providing rules for good use
cases. On the flip side, you may find the following article by Susan Lilly
on avoiding common pitfalls in writing use cases helpful:

Subject: (ROSE) Rules for well formed use cases...



Hello,

I am trying to come up with some rules for creating good, well formed use
cases.  I'm referring to concrete use cases - ones directly connected to
actors.  Our people are new to UML and use cases and keep coming up with use
cases like "Enter Line Item" (not a complete function), "Make Change" (not a
'system' function) and "Calculate Tax" (among other things, internal - an
analysis issue).   We are trying to adhere to the OMG 1.3 UML Specification
and are using RUP.

Does anyone have any ideas or suggestions on this?   Has anyone seen a list
of 'rules' posted anywhere?

Thanks in advance for any help!
Rusty Williamson
