A human-centric guide to solving complex problems in engineering management, from sizing teams to handling technical debt. There’s a saying that people don’t leave companies, they leave managers. Management is a key part of any organization, yet the discipline is often self-taught and unstructured. Getting to the good solutions for complex management challenges can make the difference between fulfillment and frustration for teams—and, ultimately, between the success and failure of companies. Will Larson’s An Elegant Puzzle focuses on the particular challenges of engineering management—from sizing teams to handling technical debt to performing succession planning—and provides a path to the good solutions. Drawing from his experience at Digg, Uber, and Stripe, Larson has developed a thoughtful approach to engineering management for leaders of all levels at companies of all sizes. An Elegant Puzzle balances structured principles and human-centric thinking to help any leader create more effective and rewarding organizations for engineers to thrive in.

Fully illustrated in color, this treasure trove features 250 puzzles on every imaginable theme and subject. The book is a bonanza of mazes, word games, visual and logic puzzles, and more.

This is not really a book. This is a building in the shape of a book...a maze. Each numbered page depicts a room in the maze. Tempted? Test your wits against mine. I guarantee that my maze will challenge you to think in ways you've never thought before. But beware. One wrong turn and you may never escape!

Most chess puzzle books put you in an artificial situation: you are told a combination exists, what the theme is and what you are required to achieve. This one is different. In a real game, a player may sometimes need to find a combination. On the other hand he may have to reject a tactical idea and simply find a good positional move. His task is to find the right move, whatever it may be. The 300 puzzles in this book put you precisely in that situation. Spectacular ideas abound in these positions, but it is for you to decide whether to go in for them, or whether you would be falling into a trap. If you need them, there are hints to help you on your way. The book ends with a series of tests to measure your skills against those of other players. For this new edition, John Nunn, a top-class grandmaster and a solving world champion, has added 50 new puzzles (with hints and detailed solutions) to test your skills to the full. For ease of following, extra diagrams have been added to the solutions throughout. Overall the book is 60 per cent bigger than the first edition.

You wake up and find yourself in a strange and eerie place. Numbered doors lead off into the unknown, but which one to select and what awaits beyond?

Gather your wits, challenge your perceptive and deductive abilities, and try to escape. But make too many wrong choices and the maze may swallow you whole. This is a mind twisting book you could read in a few minutes, but if you want to solve the mystery, prepare to spend several hours poring over the text and illustrations. You will need to go back and forth between the pages, scrutinizing each clue. You will likely find yourself doubling back and going around in circles, but the persistent reader will find their way out and meet their destiny.
