[Sigia-l] comparing personas, scenarios, uses cases, task ana lysis

[Lord, Ralph]

I agree with others that have commented. Use-cases are most useful when one
is moving ahead with engineering and construction of a system. The others
are most useful for figuring out what the users need to accomplish and how
the software should behave towards them. Not the same thing, and neither
stands on its own (although you wouldn't know that if you just examined lots
of software).
