The HCD process examines starts with the people being designed for, examining thier needs, dreams, and behaviors. The process steps through the following 'lenses':
- Desirability - What do people desire?
eg. Rocket pants, space cars, unicorns, and sporks. To be desired something dosen't necessarily have to be feasible, which brings us to... - Feasibility - What is technically and organizationally feasible?
And now we have to cross rocket pants, space cars, and unicorns off the list, leaving us to examinine the viability of sporks. - Viability - What can be financially viable?
So, I am assuming the spork business is pretty competative and covered by many interenational patents and we're back to the drawing board.
