On Forests and Trees

When an English speaker is drowning in details that make the big picture hard to see, she might complain, “I can’t see the forest for the trees.”

It’s an odd expression, partly ironic and partly humorous. When I hear it, I sometimes think of my sister, who, after moving from Indiana to Utah, complained that the mountains were getting in the way of her view. (Her tongue was firmly in her cheek… :-)

The expression also describes an important problem of software engineering–one that a lot of engineers don’t understand well enough. It’s a problem with generalization.

Book Review: Universal Principles of Design

A few months back, my friend Trev recommended this book to me. I’ve been digesting it one topic at a time, on my lunch breaks.

It is profound and fascinating reading.

This is not another software pattern book. In fact, it is not really software-centric at all. It describes truths about the way human beings perceive, reason, generalize, and communicate. Many of them have obvious application to UX, UI design, and to software in general. On the scale of profundity, it gets a 9 out of 10; I suspect that I’ll be blogging about insights from the book for months to come.

I think it’s important to look at familiar problems from new angles; many profound breakthroughs in science are attributable to cross-disciplinary insight. Though time spent in this book won’t directly hone your coding skills, it will help you see recurring problems and solutions with new eyes, and it will suggest tried-and-true criteria for evaluating design alternatives.

As a teaser, some of my favorite design principles in the book include: Interference Effects, Contour Bias, Horror Vacui, Uncanny Valley, Recognition Over Recall, Wabi Sabi, Satisficing, and Propositional Density.

For now, I’ll omit any definition of what these intriguing terms mean, and leave discovery as an exercise for the reader. :-)
