Domain-Driven Design: Tackling Complexity in the Heart of Software

 part
of a 
DOMAIN VISION STATEMENT
Semiconductor Factory Automation
The domain model will represent the status of materials
and equipment within a wafer fab in such a way that
necessary audit trails can be provided and automated
product routing can be supported.
The model will not include the human resources required
in the process, but must allow selective process
automation through recipe download.
The representation of the state of the factory should be
comprehensible to human managers, to give them
deeper insight and support better decision making.

Automation
The software should be Web enabled
through a servlet, but structured to
allow alternative interfaces.
Industry-standard technologies should
be used whenever possible to avoid in-
house development and maintenance
costs and to maximize access to
outside expertise. Open source
solutions are preferred (such as
Apache Web server).
The Web server will run on a dedicated
server. The application will run on a
single dedicated server.
A 
DOMAIN VISION STATEMENT
gives the team a shared direction. Some bridge between the high-level
STATEMENT
and the full detail of the code or model will usually be needed. . . .

A 
DOMAIN VISION STATEMENT
identifies the 
CORE DOMAIN
in broad terms, but it leaves the
identification of the specific 
CORE
model elements up to the vagaries of individual interpretation.
Unless there is an exceptionally high level of communication on the team, the 
VISION STATEMENT
alone will have little impact.
