|All of the factors
on the previous slide led to realization that the ITS National Architecture
tool needs an update.
|At the same time,
it should also be noted that the ITS National Architecture Tool has some very
unique qualities that make it much better for our purposes than the graphical
tools used in other disciplines.
Architecture tool project plans provide three views:
|1)One that shows all of the THINGS that make up the system
– software, parts in vehicles, equipment on the side of the road, etc.,
|2)One that shows all of the PEOPLE who own and manage the
things, and their relationships – often different parties with no fixed
relationships (constantly changing cast of characters), and
|3)One that shows the INFORMATION that flows between the
objects as controlled by the relationships between the people.
