Exploring Requirements One
Quality Before Design
About the Book
John von Neumann once said, "There's no sense being exact about something if you don't even know what you're talking about." In a world that is growing increasingly dependent on highly complex, computer-based systems, the importance of defining what you want to make before making it—that is, knowing what you're talking about—cannot be stressed enough.
Here's an innovative book that gives you the understanding you need to give people the solutions they want. The collaborative team of Gause and Weinberg tells how you can assure the requirements are right—before the product is designed.
Written by two recognized authorities in the field, this book is a collection of ideas developed, refined, and tested during their more than sixty combined years of work with both large and small organizations.
The techniques formulated in Exploring Requirements are not confined to software development; they have been used effectively to develop a wide range of products and systems—from computer software to furniture, books, and buildings.
Systems analysts and anyone involved with the challenges of the requirements process will greatly benefit from this book.
Renowned leaders in the software industry have this to say about Exploring Requirements:
"Anyone who wants to build a product should understand this book."—Watts S. Humphrey, SEI
