In his talk at TED conference, Alan Siegel talks about simplicity in legal communications. But then, the kind of simplicity that he describes is desirable for a lot of areas of life and work.

"I define simplicity as a means to achieving clarity, transparency and empathy - building humanity into communications."

Of course, these thoughts resonate with UX professionals. Our job, ultimately, is about humans. And this does not only include the users of the interfaces we are designing, but also all the people we are cooperating with in this endeavor. So, we should not only be "building humanity" into communications with users, but also strive for that goal when communicating with clients and other stakeholders - also to allow them to have empathy for users.

Therefore, when creating deliverables (whether the final user interface or the intermediate deliverables that get us there), we should have this concept of simplicity in mind in order to optimally support the respective communication partners. And we should also keep in mind that simplicity is not the same as (over-)simplification. To say it with Einstein: "Things should be made as simple as possible, but no simpler."
