The most important principle is to adopt a "design first" approach, making design a central element of your corporate strategy as well as your product and service strategies. This means that your products and services should be conceptualized, designed, built, and marketed using one or more design methodologies and practices, rather than relying on conventional business approaches. The advantage of design methodologies is that they can be applied to various areas, including creating companies and digital products, solving complex problems, forming new partnerships, and testing new sales and marketing strategies.
