Designed as a companion volume to the acclaimed Object-Oriented Analysis, this book focuses on the middle part of the software lifecycle: the activity of design. It shows readers how to apply object-oriented design, and how to tailor and expand the method to suit specific organization and project needs. Readers will explore the major issues in OOD; the role of OOD in the systems lifecycle; how to use graphical notation; strategies for creating design; and hints for evaluating the efficiency of a design created with OOD. For software engineers and other users undertaking real-world systems development projects and designing overall software architecture for systems will find this reference approach to improving systems design indispensable.

Economic growth occurs if output grows faster than population. Given the described assumptions about the way people behave, economic growth will occur if property rights make it worthwhile to undertake socially productive activity. The creating, specifying and enacting of such property rights are costly... As the potential grows for private gains to exceed transaction costs, efforts will be made to establish such property rights. Governments take over the protection and enforcement of property rights because they can do it at a lower cost than private volunteer groups. However, the fiscal needs of government may induce the protection of certain property rights which hinder rather than promote growth; therefore we have no guarantee that productive institutional arrangements will emerge.

Speech has arisen through the need for expression. Certain factors have contributed to making it the paramount utilitarian method of expression. There are ideas and things expressible in words, but there are ideas better expressed in music, the person with no musical ear, or without discipline in the language of music, lacks the key to the door of the world of musical experience. But we live in a world of volume and space; it is hard to conceive of the person who is space-blind or volume-deaf. The great majority of people have the means of approach to plastic beauty as part of their natural equipment. The teacher can develop this natural endowment as Necessity, the greatest teacher, has developed speech.

My work in this area started around 1950 when I was still with the Cowles Commission. I was writing a more or less expository paper dealing with activity analysis...and happened to use the term "decentralization,” which was then often applied to the market mechanism as a sort of a selling point. But when I used the word "decentralization” I thought I should explain what I meant. So I made a footnote mark, went to the bottom of the page, and began writing, "By decentralization we mean...” But then it struck me that I did not know what we meant by decentralization. That was the beginning of many years of work trying to clarify the concept, because I thought that if we think this property is so important, we should be able to define what it is.

With the technological revolution in the military field and the enormous organizational reconstruction of the army and navy, and now that their prime shock force is made up of rocketry, voices may quite frequently be heard asserting that this is an era of "push-button warfare" where man plays nothing but an auxiliary role. This view is wrong. Without arguing the great importance of rocketry and nuclear weapons, it is a fact that regardless of the scale, nature or method of warfare, man always played, and will go on playing, a major role in it. War will still require the participation of large masses of manpower- in one case directly in the armed struggle, in another, in war production and the comprehensive material backing of armed struggle.

No former age was ever in such a favorable position with regard to the sources of our knowledge of human nature. Psychology, ethnology, anthropology, and history have amassed an astonishingly rich and constantly increasing body of facts. Our technical instruments for observation and experimentation have been immensely improved, and our analyses have become sharper and more penetrating. We appear, nevertheless, not yet to have found a method for the mastery and organization of this material.... Unless we succeed in finding a clue of Ariadne to lead us out of this labyrinth, we can have no real insight into the general character of human culture; we shall remain lost in a mass of disconnected and disintegrated data which seem to lack all conceptual unity.
