How UI/UX design affects business value. Design value by McKinsey

  1. Analytical leadership. Calculating design metrics is as rigorous and regular as calculating financial metrics.
  2. Cross-functionality. Human-centricity becomes the responsibility of all employees, not just one department.
  3. Continuous iteration. Ongoing communication with the end-user to validate, test, and improve ideas.
  4. User experience. Any project starts with the user and aims to create a seamless customer experience.
