It is even predicted that new value chains will be
established on building the automation (Green?¬?eld and Short, 1994) Q3 . Since the DSM
solution becomes one of the core competencies, today it is usually preferred to keep
the maintenance in-house. Often the use of consultants only in the beginning is natural
since they don??™t always have the detailed domain knowledge of your business.
Use of consultants is then limited to a few tasks, like training or organizational
introduction. Perhaps the most typical participation is in developing supporting tools
since tool development is a key competency in very fewcompanies. In the past, the use
of external consultants for tool development was more relevant since the cost of tool
development was a major project, counted in man-years. Today metamodel-based
tools have radically changed this. For example, the implementation of a basic
modeling editor can be done in less than a man-day. In creating a DSM solution, most
of the time is spent on ?¬?nding a good abstraction for development work, not on
creating tool support for it.
Provided by a Tool Vendor If you ?¬?nd a working DSM solution, you should
start using it. This is the best option for minimizing the cost of waiting as you can use a
DSM solution that is already operational right away. Such DSM solutions are most
often made available via tools that are available as standalone products or are part of
the hardware or target environment you are already using.
