The second step to understand design is to acknowledge that your way of designing is tightly coupled with your work culture and its subcultures. There is no universal process/method that “just works”, unless by “it just works” you mean “it works but”.
Your work culture and the way of designing form a dynamic synergy of coexistence. By involving designers (good and bad), you are not only bringing in expertise, you are also bringing in a design culture that often challenges your existing work culture. Designers’ culture shapes your work culture as much as yours facilitates theirs. How prepared are you?
