= pattern of technology adoption
"In the evolution of technology, the next generation of a particular device/program often follows a well known pattern in the marketplace: its design makes it MUCH cheaper, faster, and more capable. This allows it to crowd out the former technology and eventually dominate the market (i.e. transistors replacing vacuum tubes in computation). A formalization of this developmental process is known as STEMI compression:
* Space. Less volume/area used. * Time. Faster. * Energy. Less energy. Higher efficiency. * Mass. Less waste. * Information. Higher efficiency. Less management overhead.
So, the viability of a proposed new generation of a particular technology can often be evaluated based on whether it offers a substantial improvement in the compression of all aspects of STEMI without a major loss in system complexity or capability. This process of analysis also gives us an "arrow" of development that can be traced over the life of a given technology." (http://globalguerrillas.typepad.com/globalguerrillas/2008/11/stemi.html)
