The most powerful engineering feats are the ones we don't notice. The real power of engineers and developers is in turning something incredibly complex into something amazingly simple. The automatic transmission in a car represents significantly more engineering work than a manual transmission. The best works of the automobile industry, urban architecture, and consumer electronics express how great engineering is focused on hiding complexity, not reveling in it.

The best approach to adding value to products is to add power without adding complexity. When you want to add a new feature, is there some way to add it without adding a user interface for it? Can it be reliably automated? Or is there some other feature we can modify or remove to include the new feature, replacing something old with something new and improved? Think of automobiles and how they add significant features with minimal user impact. Anti-lock brakes are a supplement to the standard brake pedal UI, just like power steering is an addition to the usual steering wheel. No training or relearning is required on the part of the driver to get the benefits of these new features. This kind of design effortwhere complex features appear simple to the usermakes great products.
