An Engineering Manager's Guide to Design Patterns - O'Reilly Media

"Instead of algorithms or code, design patterns are all about reusing the experience of developers who have devised well thought-out, time-tested solutions to object-oriented programming problems. Using O'Reilly's unique Head First methodology, this report details how a particular design pattern can solve a non-obvious design problem."
