The average book on Agile software development describes a fairyland of greenfield projects, with wall-to-wall tests that run after every few edits, and clean & simple source code.
The average software project, in our industry, was written under some aspect of code-and-fix, and without automated unit tests. And we can't just throw this code away; it represents a significant effort debugging and maintaining. It contains many latent requirements decisions. Just as Agile processes are incremental, Agile adoption must be incremental too. No more throwing away code just because it looked at us funny.
Mike begins his book with a very diplomatic definition of "Legacy". I'l skip ahead to the undiplomatic version: Legacy code is code without unit tests.
Before cleaning that code up, and before adding new features and removing bugs, such code must be de-legacified. It needs unit tests.
To add unit tests, you must change the code. To change the code, you need unit tests to show how safe your change was.
The core of the book is a cookbook of recipes to conduct various careful attacks. Each presents a particular problem, and a relatively safe way to migrate the code towards tests.
Code undergoing this migration will begin to experience the benefits of unit tests, and these benefits will incrementally make new tests easier to write. These efforts will make aspects of a legacy codebase easy to change.
It's an unfortunate commentary on the state of our programming industry how much we need this book.

Capturing a wealth of experience about the design of object-oriented software, four top-notch designers present a catalog of simple and succinct solutions to commonly occurring design problems. Previously undocumented, these 23 patterns allow designers to create more flexible, elegant, and ultimately reusable designs without having to rediscover the design solutions themselves. The authors begin by describing what patterns are and how they can help you design object-oriented software. They then go on to systematically name, explain, evaluate, and catalog recurring designs in object-oriented systems. With Design Patterns as your guide, you will learn how these important patterns fit into the software development process, and how you can leverage them to solve your own design problems most efficiently. Each pattern describes the circumstances in which it is applicable, when it can be applied in view of other design constraints, and the consequences and trade-offs of using the pattern within a larger design. All patterns are compiled from real systems and are based on real-world examples. Each pattern also includes code that demonstrates how it may be implemented in object-oriented programming languages like C++ or Smalltalk. 0201633612B07092001

Written by a software developer for software developers, this book is a unique collection of the latest software development methods. The author incudes OOD, UML, Design Patterns, Agile and XP methods with a detailed description of a complete software design for reusable programs in C++ and Java. Using a practical, problem-solving approach, it shows how to develop an object-oriented application -- from the early stages of analysis, through the low-level design and into the implementation. Walks readers through the designer's thoughts — showing the errors, blind alleys, and creative insights that occur throughout the software design process. Covers: Statics and Dynamics; Principles of Class Design; Complexity Management; Principles of Package Design; Analysis and Design; Patterns and Paradigm Crossings. Explains the principles of OOD, one by one, and then demonstrates them with numerous examples, completely worked-through designs, and case studies. Covers traps, pitfalls, and work arounds in the application of C++ and OOD and then shows how Agile methods can be used. Discusses the methods for designing and developing big software in detail. Features a three-chapter, in-depth, single case study of a building security system. For Software Engineers, Programmers, and Analysts who want to understand how to design object oriented software with state of the art methods.
"Offers a requirements process that saves time, eliminates rework, and leads directly to better software. A great way to build software that meets users' needs is to begin with 'user stories': simple, clear, brief descriptions of functionality that will be valuable to real users. ... [the author] provides you with a front-to-back blueprint for writing these user stories and weaving them into your development lifecycle. You'll learn what makes a great user story, and what makes a bad one. You'll discover practical ways to gather user stories, even when you can't speak with your users. Then, once you've compiled your user stories, [the author] shows how to organize them, prioritize them, and use them for planning, management, and testing"--Back cover.
The long-awaited revision of THE book on learning proper OO analysis and design, from UML founder Grady Booch is back!

Arguably the most important book about managing technology and systems development efforts, this book describes building systems using the deceptively simple process, Scrum. Readers will come to understand a new approach to systems development projects that cuts through the complexity and ambiguity of complex, emergent requirements and unstable technology to iteratively and quickly produce quality software. BENEFITS Learn how to immediately start producing software incrementally regardless of existing engineering practices or methodologies Learn how to simplify the implementation of Agile processes Learn how to simplify XP implementation through a Scrum wrapper Learn why Agile processes work and how to manage them Understand the theoretical underpinnings of Agile processes
Beck wants to encourage readers to re-examine their preconceptions of how software development ought to occur. He does just that in this overview of Extreme Programming, a controversial approach to software development which challenges the notion that the cost of changing a piece of software must rise dramatically over the course of time.

A Practical Guide for Everyone Involved in Product and Systems Development The fledgling problem solver invariably rushes in with solutions before taking time to define the problem being solved. Even experienced solvers, when subjected to social pressure, yield to this demand for haste. When they do, many solutions are found, but not necessarily to the problem at hand. Whether you are a novice or a veteran, this powerful little book will make you a more effective problem solver. Anyone involved in product and systems development will appreciate this practical illustrated guide, which was first published in 1982 and has since become a cult classic. Offering such insights as "A problem is a difference between things as desired and things as perceived, " and "In spite of appearances, people seldom know what they want until you give them what they ask for, " authors Don Gause and Jerry Weinberg provide an entertaining look at ways to improve one's thinking power. The book playfully instructs the reader first to identify the problem, second to determine the problem's owner, third to identify where the problem came from, and fourth to determine whether or not to solve it. Delightfully illustrated with 55 line drawings, the book conveys a message that will change the way you think about projects and problems.

In The Five Dysfunctions of a Team Patrick Lencioni once again offers a leadership fable that is as enthralling and instructive as his first two best-selling books, The Five Temptations of a CEO and The Four Obsessions of an Extraordinary Executive. This time, he turns his keen intellect and storytelling power to the fascinating, complex world of teams. Kathryn Petersen, Decision Tech's CEO, faces the ultimate leadership crisis: Uniting a team in such disarray that it threatens to bring down the entire company. Will she succeed? Will she be fired? Will the company fail? Lencioni's utterly gripping tale serves as a timeless reminder that leadership requires as much courage as it does insight. Throughout the story, Lencioni reveals the five dysfunctions which go to the very heart of why teams even the best ones-often struggle. He outlines a powerful model and actionable steps that can be used to overcome these common hurdles and build a cohesive, effective team. Just as with his other books, Lencioni has written a compelling fable with a powerful yet deceptively simple message for all those who strive to be exceptional team leaders.
