Create user centred applications, but do NOT do user centred engineering.
Create applications with thoughtful and wonderful UX, but do NOT let UX lead problem modelling and application development.
In many development teams, when UX is repeatedly emphasized, engineering process can be seriously affected.
Especially do not let the UX designing or assisting tools, like User Flow Diagram, to distract your engineering mind. In the end, what your customers see in you application is not necessarily how everything works. Even to some extent, if what users see is exactly how everything works, it may be very strong smell that the problem the application is designed to solve is not properly abstracted. Very often the reusability in the code base will be very poor as a result.
