Modeling for Stakeholder Engagement

System models can be applied to stakeholder engagement activities and linked directly to system architecture constructs. This requires the development of models that are meaningful to the stakeholder community and are linked to the more detailed constructs used during system architecture and design activities. This technique is being applied to the deployment of Intelligent Transportation Systems (ITS) in the United States, and could apply elsewhere and to other domains. ITS requires tools that fulfill the needs of widely disparate users. Transportation planners are concerned with meeting mobility needs of travelers within their operating region, which leads to a focus on needs and services. Deployers are concerned with the ability to instantiate these services using available technology, which leads to a focus on technical requirements. If sufficiently focused and approachable to both the planning and deployment communities, models can serve as the basis for stakeholder interactions and also provide the basis for subsequent design activities.
