design process


Principal Design approaches every project methodically. The success of a product development project depends upon the clarity and strength of the process. Organized into the five stages most proven to leverage our design efforts, Principal Design's purpose-driven frameworks were developed and refined to reduce risk while balancing exploration with execution. Our creative strategy is divergent to leverage resources and discovery, and convergent to select for the best opportunities.
