A technique is provided or integrating system design, sales, and manufacturing functions. Systems including networked and programmable electrical components, such as motor control centers, and other electrical power control arrangements are designed, and a database is created for the design, including component and system designation data. The database may further include configuration information, settings, and so forth. The database is used as a tool in establishing a sales solicitation proposal from which sales of the system are offered. The same database is then used to program the various components of the system, such as through a temporary network link or via a permanent data network once the system is assembled.
