Innovation Adoption Curves Variants

Innovation Adoption by Product / Service
Brendan Dunphy, Business Consultant, France, Member
We could go even further and recognise the % will vary according to product/service as well and not just industry or country, there are a lot of variables. I think the %s in the model are purely illustrative and would not bear detailed analysis.

Pareto Principle behind Innovation Adoption Curve
Geoff Dickinson
It's pretty obvious that the adoption curve is mathematically a restate or refinement of the Pareto Principle adapted to/recognising standard deviation and t factors. Thus both illustrative and mathematically averaged.
2.5% ~third standard deviation remainer.
13.5% ~ balance to get to 16% second standard deviation.
34% + 34% ~68% ~t factor for first standard deviation.
16%~ second standard deviation remainder.

Cyclicity to the Life of a Product
Rajan Mani
Speaking as a teacher of marketing and management, concepts like the Product Life Cycle and Innovation Adoption Curve suffer from the failing that they cannot be fitted into a time frame. (Anybody who could predict a time frame for these curves at the start of the cycle would have to be a damned good astrologer!) The robustness of these concepts lies in their ability to let us understand that there is a cyclicity to the life of a product, and that not everybody adopts a new innovation at the same time.
