"Karl Wiegers has written a delightful and practical book that challenges how we think about designing products. As with Karl's other books, The Thoughtless Design of Everyday Things is lighthearted, entertaining, and thought provoking. He offers many tips regarding how to do thoughtful design and design mistakes to avoid, with loads of relatable real-world examples. You'll learn something about future product design and probably be more annoyed by those who haven't."

—Joy Beatty, Vice President at Seilevel

"Karl calls out many of the egregious design errors that we've all encountered, drawing on examples from the kitchen, the car, the computer, and many other sources. Then he takes it further, using these 'thoughtless design' examples to illuminate a specific design principle the product designer should have followed. As a designer, I learned some valuable rules and processes for thoughtful design. I also learned why designers tend to make such crazy errors. As a customer, I learned how to clarify my exact needs when choosing among rival products."

—Meilir Page-Jones, author of The Practical Guide to Structured Systems Design

"This might be the most depressing book you'll read if, like me, you appreciate products that are well designed. On the other hand, it just might be the most entertaining read when you see the examples of calamitously bad products. Karl has put together here the most alarming, yet amusing, chamber of horrors of poorly, thoughtlessly designed products. But Karl also brings you wonderful insights on design, design principles, how good design comes about, and how it makes so much difference to everybody's equilibrium."

—James Robertson, requirements guru and author of Mastering the Requirements Process

"Karl Wiegers's gift is his ability to look at an important topic and write a comprehensive study that gives practical advice, illustrated by real-world examples. Interesting and insightful, I found it hard to put this book down; I just wanted to turn the page and see what came next. Anyone who designs items for real-world use—software, machines, medical instruments, homes, appliances, and the like—will find this book immensely valuable."

—Norman L. Kerth, software engineer and author of Project Retrospectives
