内容説明
"The author knows whereof he speaks. His material is sound, up-to-date, and appropriate. Robert N. Britcher has inside knowledge on one of the most dramatic software stories of our time." --Robert L. Glass President, Computing Trends What really goes on inside the world of software development? How do straightforward projects with well-defined goals mutate into large-scale disasters? How do personalities, ambitions, work environments, and time and cost limitations impact the creation of software? In a book that is both personal and technical, Robert N. Britcher brings to life the culture and infrastructure of software development. Combining history, characters, dialogue, memoirs, and technical information, he describes software development's evolution from the early systems of the 1960s and 1970s to today's high expectations for technical achievement, timeliness, and profit. Using the FAA's Advanced Automation System--one of the largest and most spectacular computing failures in the history of the field--as a backdrop, the author draws on his first-hand experiences to illuminate the reasons why software projects succeed or fail. He examines theories of programming, the process of design, and the methods by which code is written and tested. In addition, Britcher discusses the human element, decrying the "impossible profession" and describing the daily experiences of "life on the project." Looking at the current software development environment, The Limits of Software explores how technology changes methods and how today's market demands affect software development. The book also examines the many forces behind the current push for the development of the "one great system." In this extraordinary book, Britcher offers a long-standing insider's perspective on the past and present of the computer industry, complete with its many foibles and achievements. He looks to the future with both optimism and trepidation, hoping that the industry can accomplish real gains while reaching for worthwhile goals. 0201433230B04062001

An analysis of a major success and a major failure
1999/12/31
形式:ペーパーバック
The same task has produced what is arguably the greatest triumph as well as the greatest failure in software development. Air traffic control is a task where 24/7/365 (functional 24 hours a day, 7 days a week, 365 days a year) must be a law rather than a mantra. The national air traffic control computer system known as the 9020 was written using punched cards and is roughly 500,000 lines of code. Despite all the noise about problems and obsolescence, it has scaled up so well that it is used to control several times the number of flights that it did when it was developed in the seventies. The project to replace it, called the Advanced Automation System, cost several billion dollars and yielded nothing usable, although it did make the developers a great deal of money. Within these two extreme bookends there are several lessons to be learned and that is the point of this book.
The author worked on the 9020 system and spends a great deal of time ruminating on how things were, from coding to the personalities of those who built it. Packed within this is one clear lesson. In all successful software projects, there is a small, core group of people who do the bulk of the true work. Enlarge that core, either by increasing the numbers or infiltrating it with bureaucracy, and the chances of failure plummet. This is the conclusion reached by the author in his analysis of why the Advanced Automation System failed. The secondary lesson is that the very stability of the air traffic control system makes it fragile and difficult to change. There is no easy way to make changes to the system, where the simple movement of a control knob several inches can create problems.
There are lessons for developers sprinkled throughout the book, although it is sometimes necessary to read carefully to find them. Presented in the form of a non-sequential journal, the flow sometimes goes sideways, but it nearly always manages to make a valid point.

A beautifully written book.
1999/9/3
形式:ペーパーバック
The Limits of Software is eccentric and eloquent. I've never read anything quite like it. Somehow the author has mixed amusing stories, characters and dialogue, and technical material in the right proportion: the book is not just informative, at times it is moving. The book, at 200 pages, reads like a 20-page article; but it lingers like a fine novel.

An excellent narrative of software development issues.
1999/8/9
形式:ペーパーバック
This work by the author provides an excellent narrative on software development issues from the perspective of those actually doing the development. The experiences described are typical of those lived by many software developers. The book is easy to read and captures the reader in the intensity of the authors experiences.
