What I do.
Research.
Spending time understanding what/who you are designing for is a huge first step in the design process. I like to spend time doing independent research as well as listening to what people like or are looking for as it relates to each project I work on.
Prototype.
Creating a first viable concept with both virtual models and something to hold in your hand offers a powerful step in narrowing brainstormed concepts. I approach this differently depending on the scale of the project and how I would like the customer to be able to interact with the prototype to provide feedback.
Design.
Narrowing down the prototypes to a final option that can be scaled up is something I really enjoy doing. Bringing a concept into reality has real world limitations that I love finding solutions to, everything ranging from manufacturability to cost come into play all while keeping as true to the design intent.
Repeat.
Designing is never really complete. With a commercialized product in hand there is always room for refining and improving the product and all of this learning is fed back into new product concepts and design.
