The BIZBOK introduces the notion that value streams include the concept of a binding business object(s) whose state, together with entry and exit criteria controls the sequencing of value stream stages. How should BACM represent this concept? Is it explicit in the metamodel, or is it the result of analysis or some combination of these?

The ability to associate products with customers is important. In the current metamodel, this connection can only be made by joining a customer targeted by a value proposition with a product offering where the value proposition is of the product offering. Should the metamodel include a direct relationship between product offering and customer? Should this relationship be a shortcut?

The justification for namespaces is to permit parts of the model to be used independently. The current packaging is close, but crossmaps between value stream and capability are defined in Capability and crossmaps between ValueItem and Outcome are defined in Customer. Customer mixes together Journeys and Value Streams. Consider repackaging to eliminate crossmaps from the core packages and add new packages with just the crossmaps. This would also benefit use of the OWL as a group of ontologies instead of one large one.

JSON is an increasingly popular serialization format. JSON-LD provides some key additional capabilities.
