Focusing on the core business is what differentiates real product design from interface design or even user experience design. Fundamental product design is really hard and requires a lot of legwork, but this is what designers at the highest level do — and it’s why their work is better than yours.
When you accept the reality that design decisions are coming from outside your group, by people without “design” in their job titles, you approach your co-workers differently . Now they’re not just your co-workers — they’re your design team.
Whether you like it or not, whether you approve it or not, people outside of your design team are making significant design choices that affect your customers in important ways. They are designing your product. They are designers.
