Every design begins with an idea. The process of going from thought to a usable product must go through the design process.
What is the problem your trying to solve? What do you need to improve? Why is this needed?
These questions fuel the conceptualizing phase. Blue sky ideas, narrowing down to what fundamentally is important for the product to function and succeed.
Getting those blue sky ideas onto paper where you can visualize the form and function of the product. This is the time to play with as many forms, colors and ideas as possible. Never be afraid to draw something that might not be possible.
Through physical and digital forms, getting your hands on the materials, parts and tools needed to create the product. Prototyping at many levels to get it just right is the key to conveying the design to anyone who has never seen it before.
