Generativity: What makes something generative? There are five principal factors at work: (1) how extensively a system or technology leverages a set of possible tasks; (2) how well it can be adapted to a range of tasks; (3) how easily new contributors can master it; (4) how accessible it is to those ready and able to build on it; and (5) how transferable any changes are to others—including (and perhaps especially) nonexperts.
Leverage: Leverage makes a difficult job easier.
Adaptability: Adaptability refers to how easily the system can be built on or modified to broaden its range of uses.
Ease of mastery: A technology’s ease of mastery reflects how easy it is for broad audiences to understand how to adopt and adapt it.
Accessibility: The easier it is to obtain access to a technology, along with the tools and information necessary to achieve mastery of it, the more generative it is.
Transferability: Transferability indicates how easily changes in the technology can be conveyed to others._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
