Prototyping is a structured process, with focus on assessing impact on the Business and its Value Objectives (Plan Values).
Models that can be created in VMP, to support Prototyping, are Business Models. These can be created directly, but may also serve as structured counterparts of what has been conceived via the graphical Maps during Discovery.
In the Prototype stage it is also possible to generate Process (BMPN) and Case (CMMN) models from Value Streams (and generated target elements in the structured Prototype model). This enables further downstream analysis and development, towards business automation, in scope of the Plan.
