Hi Kristian
We have done a similar project recently. What we did was:
For modul A (which was mandatory) we had a Use Case with a Normal
Flow
If modul A was combined with modul D (which was optional) we
described the changes to the normal flow in A as an
alternative flow in A. So alternative flow 1 was normal flow with
the changes caused by modul D's involvment.
For modul D the normal flow was based on the alternative flow in A.
etc.
We also created activity diagram for each combination.
Brgds,
Annette

Subject: (RUP) Use cases and highly configurable systems
Hello all!
Anyone, experience or ideas about the following case.
We are modeling a new release of a product family. Previously the
functionality described in the use cases was designed and implemented as
such. With this new release a high degree of configurability has come into
the picture so that business designers can use a specific tool to create
and configure the business processes using what we call process components.
These can be added, removed or changed. Some of them are mandatory, some
optional. In some cases the order of steps in the flow can be changed. The
software should be able to function and these processes should go the way
the system has been configured.
So the question is, with systems that almost everything can be
configurable, what would be the ideal approach to describe the use cases?
Here are some ideas:
- Describe with use cases how the configuration is done (well, this is
obvious)
- Describe with use cases how the functionality will be after configuration
has been done (end user functionality)? The difficulty is that the
possiblities are numerous because the processes are designed and
configured, not implemented as a part of the product.
- We thought of identifying examples of most likely end user functionality
and model these as use cases? But these would be only configuration
examples.
- Processes are product specific and also products are created from product
components and highly configurable as the processes. How to map these with
the processes and also identify simililarities between processes of
different products.
We have modeled the product structure and process structure so that they
are very modular.
Any thoughts?
