System modeling business process

The system modeling business processes provide the creation of the system model solutions in the context of the program or project. Solution models may be classified in a library, for example, when several systems designers are collaborating on a program or if they are candidates for possible reuse.

Business process	Description	Roles
Plan program or project	(This is a prerequisite process that assumes the product is a new concept.) Provides the steps to set up the study project, including: create the project context; create the study project (the project acts as a collector of artifacts in the study); create the system context, searching for and copying architecture elements where appropriate; define the conceptual system architecture, cascading or decomposing requirements from functional model to system model when appropriate; conduct a feasibility study, searching for and comparing similar solutions.	System architect, Configuration developer
Model the solution system	Creates a logical decomposition of the system that satisfies the solution needs. Tasks include: author the system model (a conceptual solution that may span multiple features); decompose the system model into blocks that eventually correspond to sub-assemblies and components; if necessary, consume the next level of requirements and iterate; define and manage the system model interfaces and ports that link the model elements; validate and release the system model into the program architecture.	Technical architect, System analyst, System designer
Consume model solutions from library	Provides the classification of system models in a library for collaboration between participants or subsequent reuse. Tasks include adding models to the library and retrieving model solutions from the library.	System architect, System designer
Prepare data for simulation	Associates parameters with system model blocks, allowing their characteristics to be simulated. Successful achievement of targets confirms that requirements are satisfied. Tasks include: assign requirements and function occurrences to model elements using trace links; allocate parameters and targets to model elements; request analysis.	System architect, System designer
