摘要：

Inadequate requirements cause many problems in software products. This paper reports on an experiment to reduce the number of requirement defects. We analysed the present defects in a real-life product and estimated the likely effect of 44 prevention techniques. We had hoped a novel combination of techniques would come up, but the best approach was quite well known, although new to the company: study the user tasks better, make early prototypes of the user interface, and test them for usability. This approach was tried out in a new development project in the same company. Due to the new approach, there was no doubt about requirements during programming, and as a result it became the first project in the company that was completed on time and without stress. Usability was drastically improved, and as a result the product sold twice as many units as similar products, and at twice the unit price. © 2001 Springer-Verlag London Limited.
