What do you think of Dieter Rams' twelve principles of design? Is anything missing or no longer relevant?
Yes, as Mr. Spott so kindly pointed out since my brain compartment was elsewhere this morning - 10 principles not 12. Unless someone has 2 to add.
@wellsriley blogged this year about an eleventh principal -- Good Design is Iterative (blog.wells.ee). I agree that this principal works in combination with the other ten principles, but not in isolation. For example, SaaS software gives the possibility of incremental enhancements that can enhance the user experience. However, that can also allow software that perpetually disrupts the user experience if new features are introduced that don't fit well into the existing user experience or if something in the software is refactored in order to improve it. Good design would easily accomodate new features without disrupting the user experience.
In this article, he also lumps Responsive Design under this principle, but I think that is well covered under design being long-lasting and thorough.
