the design process

We help solve your company's most challenging design needs using a multi-step design process. We start with problem identification, research, and conceptualization to develop a set of possible solutions. A solution is then selected based on factors such as customer requirements, manufacturability, and cost. We then carry the product into a detailed design phase, through production planning, prototyping, testing, and production.
