I work on many projects with very talented people. Momentum is a word often used to describe a certain condition of a project or the project's economic, political, and social milieu. For example, there is favorable momentum in the legislative floor debate on wind energy or providing economic incentives to encourage data warehousing facility location. The price structure of a product or stock offering is generating marketplace momentum.
The simple sketch illustrates momentum as moving power. Specifically, people work collaboratively to create ideas such as the computer chip. Market power shifts from an industrial age to a computer age. Creation of cell phones shifts power further on the horizon. Smartphone's are built on the momentum generated from the merger of power of computing with hand-held digital power. Now observe the revolutionary transformation of the global marketplace.
Similar power shifts occur in neighborhood improvement efforts. For example, residents of an urban neighborhood collectively act to address public safety by increasing the stock of affordable homes. They work collaboratively with community bankers, lenders, housing developers, and the city council. The city council provides development incentives through tax increment finance structures (TIF). That, in turn, provides bankers and lenders collateral necessary to offer loans. Developers serve as a market intermediary between lenders and the residents. In time, more families occupy affordable homes in safer neighborhood environs.
That is momentum -- moving power.
