The concept of today's technology has been dropped. Everything is now either oobsolete or experimental. Yesterday's technology is appealing only because it is tried-and-true and prices are reduced for clearance. Tomorrow's technology is exciting, somewhat expensive and not well tested.

In the field of architecture, where most firms are medium or small, having limited resources, the high cost initially required for a CAD installation was generally impossible to meet not too many years ago.

From spreadsheets and CAD graphics to network file systems and distributed database management, the basic systems and application tools have matured to the point that the possibilities are now limited mainly by how creatively the architects can apply them.

CAD systems on the market today are not so different from the systems of the mid 70s, except they have gone from hardware costing a hundred thousand dollar to PC based systems, costing under ten thousand dollars.

Choices of hardware and software for CAD systems undergo continual changes in power and efficiency. There will come a point where upgrading will create more a deficiency rather than an augmentation of capability efficiency and overall function. Thus it becomes a major problem for the prospect buyer.
