The last decade has seen a revolution in software engineering tools and techniques. This revolution has been fueled by the ever-increasing complexity of the software component of delivered systems. Although the software component of delivered systems may not be the most expensive component, it is usually, however, “in series” with the hardware component; if the software doesn’t work, the hardware is useless

Software is intangible Hard to understand development effort Software is easy to reproduce Cost is in its development —in other engineering products, manufacturing is the costly stage

Background OF TECHN Why is Software Engineering Hard? “Curse of flexibility \And they looked upon the software and saw that it was good. But they just had to add one other feature ... No physical constraints
