Design Philosophy We design by three key themes Useful Design with a specific issue in mind Reliable Design for longevity and durability Affordable Design to lower cost And we design following four careful steps I. OBSERVE Observations are needed to ask interesting questions about the world: why do people have a certain issue? What can be done to help? Look at the world, come up with a question. II. IDEATION Ideation takes in the observations and aims to produce new and creative solutions to those issues; here's what I imagine doing better or differently. III. PROTOTYPE Prototype something small but meaningful, a really simple model, quick sketch or computer simulation. Test it with people, see what does work and what doesn't. IV. ITERATE Iterate your design. Products are never correct the first time around. Change the design, fix to problems and test it again.
