Usage scenarios vs. Requirements matrix
Solid usage scenarios
Relationship to Usage Scenarios
Usage scenarios or "use cases"; provide a means of determining:
Are the requirements aligned and self-consistent?
Are the needs of the user being met as well as those of the enterprise?
Are the requirements complete?

Things to Think About
Brainstorming: "if we do all of these things, will we succeed?"
Refactoring and rearranging the hierarchy are part of the process (the hierarchy itself is important information)
Leave no stone unturned: every idea is a good one
Different levels of abstraction require careful navigation!
Conclusion
CSF analysis:
Produces results that express the needs of the enterprise clearly and (hopefully) completely
Allows us to measure success and prioritize goals in a sensible way
When used together with traditional usage scenarios, ensures that the needs of both the user and the enterprise are being met displayed 300 characters
