@PeterCool There is a lot of complexity hiding behind that simple question. I'll try to give you few answers based on my organization's usage of HOPEX.
You asked "how to inventory single application, used by different departments?" You suggested perhaps maintaining separate application objects - presumably one for each department.
We don't do that - we inventory a single Business Application and then create different mappings to show how different departments use that application.
Business Lines
Now, an Application object can be linked to a "Business Line" object. We do that. So, we can very easily indicate that a single application is serving multiple departments (i.e. multiple business lines). You will find the Business Line link in the Characteristics tab of the Properties page of the Application object.
Application Installations (we don't use this - but it is available and seems to address your question)
Each Application record in hopex can have a defined Installation. You can define things like:
- Hosting Location
- Deployment Support
- Owned Usage Context
- Consumer (i.e. department)
Exhibited Business Capabilities
Lastly, if you have a Business Capability Model at your org - you can use the Enterprise object to setup a dedicated Business Capability map for each business segment. Than, you can map applications to business capabilities for each segment separately.
Hopefully this gives you some ideas of what is possible. Like I said - you asked a simple question - but the answer depends on the context and specific details of what you need. 😉
