„Structured design does not scale up well for extremely complex systems, and this method is largely inappropriate for use with object-based and object-oriented programming languages.“

„Like structured design, the term object-oriented design (OOD) means different things to different people. For example, OOD has been used to imply such things as“

—  Edward V. Berard

The design of individual objects, and/or the design of the individual methods contained in those objects
The design of an inheritance (specialization) hierarchy of objects
The design of a library of reusable objects
The process of specifying and coding of an entire object-oriented application
The term nonformal is used to describe approaches to OOD that are not well defined, step-by-step, or repeatable, such as those that emphasize the design of individual objects, specialization (inheritance) hierarchies, and libraries of objects...

„The control objects model functionality that is not naturally tied to any other object… We do not believe that the best (most stable) systems are built by only using objects that correspond to real-life entities, something that many other object-oriented analysis and design techniques claim… Behavior that we place in control objects will, in other methods, be distributed over several other objects, making it hard to change this behavior.“

„Systems inquiry has demonstrated its capability in dealing effectively with highly complex and large-scale problem situations. It has orchestrated the efforts of various disciplines within the framework of systems thinking. It has introduced systems approaches and methods to the analysis, design, development, evaluation, and management of systems of all kinds“

„Shed the idea that you were programming in an OO style. There is no such thing. You were only programming a particular object system. Now you get to program a different object system.“
