The best way to have good ideas is to have many, different ideas. The best way to have different ideas is to engage people from a rich diversity of backgrounds & perspectives.
Design for product is quintessentially human-centered; it directly connects those to be served with the process of evaluating their needs.
A great product is not just the sum of good ideas, executed well; it results from the continual pursuit of fit, refinement, and evidence of value delivered.
The products that best serve the needs of people come from conscious design that engages those people, early and often.
Products deliver massively greater impact when collectively formed into a fabric of touchpoints within an intentionally designed ecosystem.
Designing a product is just the beginning. Designing the system is where value is delivered at scale.
