What is the Correct Definition of "Business Application" in the CSDM and the Real World?

In this very useful job aid Service Offering Success PDF from ServiceNow , the business service name is
"General Ledger"  as is the Service Offering which creates some ambiguity when trying to understand the relationship model.     In our implementation, we are often finding we have named the Business Application with the same name as the Application Service, which causes some Ambiguity.    In this example the Application Service name is the Software Product Title.          So in our world our Business Application will have something that looks a lot like a Product Title. 
Using the example, SAP finance would be in the Business application box.     

What is best practice?   Is the Business Service name a general term for what the Product is used for in the Business? 
It would be great to have a field level definition of these central CSDM data items, so that we can migrate our use to the intent.

• Business Service: Collaboration
• Service Offering: Email
• Business Apps: Microsoft Exchange, Kaspersky Security
• App Service: Microsoft Exchange - PROD

To eliminate confusion between Business Service and Business Application names in ServiceNow, it is recommended to follow a clear naming scheme. Business Service should refer to the functionality provided for the business (e.g., “General Ledger”), and Business Application should refer to the specific software that supports this service, like “SAP Finance”. By the way your best digital business card I saved and will keep in mind) Application Service will be a specific instance or deployment of that application, like “SAP Finance Production”. It is important to create clear definitions for each of these elements in the data field to avoid confusion and ensure uniformity in the use of the CMDB, and to provide training to employees on the difference between these terms.
