If you create software using object-oriented languages and tools, then Responsibility-Driven Design has likely influenced your work. For over ten years Responsibility-Driven Design methodology has been the standard bearer of the behavioral approach to designing object-oriented software.
Object Design: Roles, Responsibilities, and Collaborations focuses on the practice of designing objects as integral members of a community where each object has specific roles and responsibilities. The authors present the latest practices and techniques of Responsibility-Driven Design and show how you can apply them as you develop modern object-based applications.
Working within this conceptual framework, Rebecca Wirfs-Brock and Alan McKean present how user requirements, system architecture, and design patterns all contribute to the design of an effective object model.
They introduce a rich vocabulary that designers can use to discuss aspects of their designs, discuss design trade-offs, and offer practical guidelines for enhancing the reliability and flexibility of applications.
In addition, case studies and real-world examples demonstrate how the principles and techniques of Responsibility-Driven Design apply to real-world software designs.
Documenting and describing a design, focusing on use cases, design conversations, and annotations. As all experienced designers know, software design is part art and inspiration and part consistent effort and solid technique.
Roles, Responsibilities, and Collaborations will help all software designers--from students to seasoned professionals--develop both the concrete reasoning skills and the design expertise necessary to produce responsible software designs.

We hope you become adept at thinking in objects and excited about devising solutions that exploit object technology. Design choices can only be considered in light of what you know to be relevant and important. To achieve good results, however, you need to learn to discriminate important choices from mundane ones, and to acquire a good set of techniques that you intelligently practice.
In this book, we present informal tools and techniques that don't require much more than a white board, a stack of index cards, a big sheet of paper and chairs around a table. Oh yeah, be sure to bring your brain, too!
But more important than a grab bag of techniques are the fundamental ways you view a design. Although the techniques we present in this book are independent of any particular implementation technology or modeling language or design method; our approach to object design requires a specific perspective: Objects are not just simple bundles of logic and data This approach, called Responsibility-Driven Design, forms the basis of how to reason about objects.
Most novice designers are searching for the right set of techniques to rigidly follow in order to produce the correct design. In practice, things are never that straightforward.
For any given problem there are many reasonable, and a few very good solutions. People don't produce identical designs, even if they follow similar practices or apply identical design heuristics.
For each problem you approach, you make a different set of tactical decisions.
The effects of each small decision accumulate. Your current design as well as your current lines of reasoning shape and limit subsequent possibilities. Given the potential impact of seemingly inconsequential decisions, designers need to thoughtfully exercise good judgment. Your primary tool as a designer is your power of abstraction--forming objects that represent the essence of a working application.
In a design, objects play specific roles and occupy well-known positions in an application's architecture. Each object is accountable for a specific portion of the work. Each has specific responsibilities.
Objects collaborate in clearly-defined ways, contracting with each other to fulfill the larger goals of the application. Design is both a collaborative and a solo effort. To work effectively you not only need a rich vocabulary for describing your design, but strategies for finding objects, recipes for developing a collaborative model, and a framework for discussing design trade-offs.
