A local restaurant franchise came to us with a request. They would be opening new locations soon, and wanted to have a special attraction for their patrons. We decided that their main product offering might be appropriately exciting as a projectile…

Brainstorming with the project sponsor’s executive team, we decided on a holiday deadline to introduce our hot-bun launching gizmo. Several rounds of prototypes, assembly strategies, propulsion and trigger mechanism later, we defined the best trajectory and safest option for the restaurant layout.

The hot-filling, sticky bun treats would require custom packaging designs, complete with parachutes and stable origami folded deployments. It proved to be a delightfully resounding success!

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. While the product development process can be customized to apply effectively to the needs of the customer and adapt to changing business objectives, Principal Design’s 5 step process is a framework that guides the design team and encourages communication and stable execution.
