Software Measurement

Software plays an important role in our life. We want products which affect our lives has quality attributes. We need quality software. In order to determine quality of software we must have some metrics to measure quality. The key point here is quality of the same product may be change. Software is not an exception. So if we determine quality attributes of the software we can also have more precise, predictable and repeatable control over the software development process and product. If software engineer know what will he/she do, then we can "measure" software more easly. Most of time we do not know exectly what is the problem. With only a small understanding of the desired software system, estimations of costs begin.

In the early days of computing, software costs represented a small percentage of the overall cost of a computer-based system. Therefore, a sizable error in estimates of software cost had relatively little impact. Today, software is the most expensive element in many computer-based systems. Therefore, a large cost-estimation can make the difference between profit and loss.
