Needs
The Stakeholders' Needs listed below are designed to answer two basic questions:
– What does the System(s) need to do?
– What do users need from the System(s)?
They are written from the perspective of a system user or stakeholder in that system and are categorized by the Intelligent Transportation System (ITS) Service Packages that comprise the regional architecture. Service Packages provide an accessible, service–oriented perspective to the overall system architecture used to describe the region or project. They identify the pieces of the physical view that are required to implement a particular ITS service. Each of these service packages has a set of Needs associated with it that can be used as the basis for stakeholder validation, setting proper expectations, and eliciting requirements for the systems and devices to be implemented.
