Tim Altom said:

A user scenario, generally speaking, is a total environment within with the 
user operates, including the user's attributes themselves. You might call 
these "user studies" or something similar. A good user scenario goes far 
beyond the simple controlled environment of a laboratory and takes into 
account whatever is in the user's everyday environment.

Tony Markatos responds:

That is a different 'User Scenario' than the original question was asking 
about.  The question asked about Use Scenario in the context of functional 
analysis - specifically comparing Use(r) Scenario with Use Case.

As I (seperately) posted, in the main, a Use Case is the same as a Use(r) 
Scenario - they are both functional analysis techniques to specify processes 
(tasks) accomplished and the detailed steps within.  The following quote is 
from an on-line Larry Constantine article (http://www.foruse.com, Select 
'Resources', Select 'What Do User Want', Goto to pages 4-6.)

*****Start quote from article:

" USE(R) SCENARIO is a concrete description of a very specific interaction, 
but one that is chosen to be typical or representative.

Example:  Ian Smith calls TechnoTech Support line at 4 am and hears the 
Enter Customer ID prompt.  He then keys 17682002 on the telephone keybad, 
after which he hears the menu of TechnoTech product lines.

USE CASE is a generic scenario, describing one kind of interaction with a 
particular interface.

Example: Customer calls, the support line and hears the log-in prompt.  
Customer then keys in an ID number and hears a menu."

*******End quote from article





Not so when talking about comparing Use Cases vs Use Scenarios (which is 
what the orginal question asked about
