“In your work as a UX professional, do you ever find that you need to convince people that the team should follow a user-centered design process? Do you need to convince stakeholders they should do user research? Do you try to get user experience thinking inserted earlier in the project lifecycle? Perhaps you need to sell yourself or your company? I certainly do. In fact, I find that there are many of these persuasive moments in the practice of user experience design. To be successful as a UX professional, you need to know how to be persuasive.”
Convincing is as hard as persuasion.
