Look. The problem with design (not only here but everywhere) is that for some reason techies also think they can be concept engineers.
The development process requires a meeting of the minds of people with two thoroughly different ways of thinking.
And there needs to be on-going, productive and efficient, systematic interaction between conceptual thinkers and technical thinkers. This requires back and forth dialogue between concept designers (to present what is ideal) and technical designers (to present what is technically possible). One side builds upon the other towards continuous, incremental innovation.
Of prime importance, however, is that there is a friggen DESTINATION towards which this incremental innovation is 'developing', else you won't have development at all, but, rather, just a blob of random changes that you might say has 'evolved' on its own, but to no positive effect. It is hard to tell evolution and de-evolution aprt sometimes, especially if you are immersed in that which is either de-evolving or evolving.
To ensure development, we have to get away from that paradigm. Forget about evolution. focus on clear, direct, development goals, within a shared vision for what would be a GOOD end result.
In this process, equal importance needs to thinkers on both sides of the development process equation: concept and feasibility.
The problem has been a culture of technocratic draconianism plaguing our societies seeping into development processes whereby techies consider only the technological 'feasibility' of an idea, rather than engaging in a pragmatic dialogue between what is ideal and feasible, towards. ever-increasing idealism as idealism begins to change what is feasible technologically. Those that have this culture of technocratic draconianism fail.
Those that conceptual ideals can manifest technological feasibilities succeed.
I would join the development team if everyone on the team understood and agreed that it is not only technological feasibilities which drives conceptualization towards innovation, but also conceptualization towards innovation which drives technological feasibility.
