Sustainable Packaging Innovation Model

Based on the problem areas and possible solutions that we had identified last week, I picked up the theme of 'Innovation in (Sustainable) Packaging". As a result of desk research, reading already available study material and some contemplation, I am presenting a Sustainable Packaging Innovation Model (SPIM) here.

Five pillars of this model:
Understanding Consumer Psyche
This is to understand what goes on between customer's first interaction with the package and the final purchase. Does the 'green' factor presented on the packaging really motivates people to buy that product? Research shows that as more and more people are becoming sensitive towards the 'go green' initiatives, they feel a sense of redemption while buying products sustainly packaged.

Packaging as a Service
Customer Satisfaction in Packaging is a function of safety assurance, convenience and information available on the package. Doesn't this equation make packaging a service?

Simplified Innovation Steps
Can innovation be as simple as answering four questions? Or as difficult?

Packaging Innovation Guides
Again, consider packaging as a service rather than a tangible good. Designer looks at the function of this service hence exploring and defining the functions user is most interested in is the key.

Materials and Processes
Isn't picking an eco material for packaging is far better and redemptional than picking an un-eco one?

I am dubious if I should call this an 'innovation' model but the idea is presented here probably helps looking at packaging from a much broader perspective rather than looking at it few folds of the paper or the metal.
