This is a "how to" book on program design. It is about a host of topics that are important to programmers but that we often don't have the pressing need, the time, or the inclination to learn or to re-learn. Every programmer knows that software development is much more than coding, but few can find the time to study concepts in software engineering, system analysis and design, software models, design patterns, and the fundamentals of indirection and object-oriented constructs, especially when there is an unfinished project at hand and a boss or customer waiting for a project.
