A New Spider on the Web [chapter]

Arthur Tatnall, Bill Davey
2005 E-Training Practices for Professional Organizations  
In this paper we propose an ecological model of technological innovation, and show how it can be applied to considerations of the adoption of e-training products and methods.  ...  The introduction of a new e-training technology is all very well, but the important question is: will it be successfully adopted and used?  ...  In Nature, releasing 1000 baby spiders-all the same product-will result in only a few successes as the complex environment interacts with each potential spider.  ...
