I liked this article. In some ways, it articulates the frustrations and challenges UX professionals who work in small consultancies like us face day in day out.
Such projects serve as moments of enlightenment for our clients, seeing the world from a different view, that of their users or consumers; and they’re a necessary evil: we learn something, but not necessarily with enough confidence to make seemingly dramatic recommendations. The important thing that such projects should achieve is to motivate the client to discover and solve these issues.
Egocentrism is a habit that can be broken. As UX professionals, we just have to keep on beating the drum and selling the kool-aid with passion.
