This is my favourite concept for describing how to cost effectively iterate complex systems solutions within a given set of constraints and conditions. That is, the ideal solution for best fit, can be said to lie in the shaded area as shown in the graph above.
This approach to solution framing comes from operations research – what is the optimal solution that minimizes resources (inputs) for maximum outputs (value creation).
I first used this in a speech I gave at the CII NID Design Summit back in the December of 2006. Oh my, has it been ten years already? How time flies.
As Granny was saying, with this conceptual framework for problem statements, one is assured of the maximum constraints possible i.e. the most inclusive design is set up as the ideal – affordable, accessible, and equitable.
Even if language and literacy put up barriers between people connected to each other via their mobile phones, especially smartphones, can’t we not design a universal user interface, such as Ted Boulou’s Somtou device, that could use all the power of the tech at our fingertips to do the greatest good towards a more inclusive internet than all the free wifi in the world. There, I said it.
