But design is different. PMs and engineers cut design details all the time. We define functional (and, therefore, launchable) in terms of whether it’s possible for a user to accomplish a task, not whether it’s easy, or enjoyable, or even whether it’s a task the user has any interest in accomplishing.
There is No Design Metric
Dave Feldman

It’s so true. And suddenly everybody is a designer and can determine the most appropriate sollution, by cutting the design details and user paths in half.
