design is not only visual
We design systems, we design for outcomes, and we design visual experiences.
Design is not only visual. Design is the act of envisioning a future state, defining the necessary components of that state, and outlining the operating model required to make that future state a reality.
With high quality design in place, you can begin to execute on your vision all while measuring your actual vs expected performance to ensure you have the chance to adjust designs where needed in order to optimize for the mechanics of various situations.
