That to me would be an IVP and not a use case.
Use Case is more like what the list has been commenting on:
A use case is a concept used in software development, product design, and
other fields to describe how a system can be used to achieve specific goals
or tasks. It outlines the interactions between users or actors and the
system to achieve a specific outcome.
In software and systems engineering, the phrase use case is a polyseme with
two senses:
A usage scenario for a piece of software; often used in the plural to
suggest situations where a piece of software may be useful.
A potential scenario in which a system receives an external request
(such as user input) and responds to it.
This article discusses the latter sense.
A use case is a list of actions or event steps typically defining the
interactions between a role (known in the Unified Modeling Language (UML) as
an actor) and a system to achieve a goal. The actor can be a human or
another external system. In systems engineering, use cases are used at a
higher level than within software engineering, often representing missions
or stakeholder goals. The detailed requirements may then be captured in the
Systems Modeling Language (SysML) or as contractual statements.
I have been trying to see how those entries on USE CASE apply to a purchased
software.
I can see creating IVPs to ensure the software is working correctly. I
cannot see how to create a use case between the software and the actor.

Your use cases would be to write a tape, read a tape, scratch a tape etc.
etc.

So if I am planning to update my tape management system, would I be able to
create a use case? The software is from a vendor. The process is invoked
whenever a tape mount request is made.
So I am not sure how w Use Case would apply
Thank you

I would suggest choosing a function or two that you're planning on
exploiting on the new release, and have those be the use cases.

Subject: [EXTERNAL] Does the term USE CASE apply to system software upgrades
List -
I am being aske to create USE CASES for system software. My brain is not
able to coordinate USE CASE with system software updates
It seems the phrase USE CASE applies more to SYSTEM Software development
than a System Software Upgrade
For Example, If I am upgrading from z/OS V2.4 to V2.5 - I am asked to supply
a use case.
Any guidance on how to do this?
Thank you
Lizette
