What the author of this article is talking about is precisely the type of disconnect between designer and user, between technician and layman, that I was referring to in part 1 of this post. His comments, focused though they are in security in connection with the Internet of Things, has broader implications for technology designers in many disciplines, who all too often lose sight of the need, first and foremost, for the product to work in the way that the consumer requires.

Be less insular, don't get hung up on terminology, focus on practical solutions to your customers' issues, don't be a barrier to their objectives... Come to think of it, it's a lesson that a good few lawyers could do with learning as well!
