"Frameworks are white boxes to those that make use of them. Application developers must be able to quickly understand the structure of a framework, and how to write code that will fit into the framewor…"

"Users can work with analysts and object designers to formulate and tune system requirements. People from business, analytical and object design disciplines can come together, learn from each other and…"

"Experienced object designers explore the design space from many different angles. They refine ideas of how their system should respond while they are in the middle of building and discarding ideas abo…"

"An Interview with Rebecca Wirfs-Brock"

"A subsystem is a set of classes collaborating to fulfill a set of responsibilities. Although subsystems do not exist as the software executes, they are useful conceptual entities."

"Frameworks are skeletal structures of programs that must be fleshed out to build a complete application. For example, a windowing system or a simulation system can both be viewed as frameworks fleshed…"

"The goal of is to improve encapsulation. It does so by viewing a program in terms of the client/server model."

"Responsibility-driven design specifies object behavior before object structure and other implementation considerations are determined. We have found that it minimizes the rework required for major des…"
