Several important test-related issues have emerged from the previous discussion. We have learned that

1. there is a demand for software of high quality with low defects;

2. process is important in the software engineering discipline;

3. software testing is an important software development sub process;

4. existing software evaluation and improvement models have not ad-equately addressed testing issues.

An introduction to the Testing Maturity Model is now presented to the reader as a framework for discussion of these issues, and as a means for addressing them. The model is discussed in more detail in later chapters of this text. The focus of the TMM is on testing as a process in itself that an be evaluated and improved. In the testing domain possible benefits of test process improvement are the following:

• smarter testers

• higher quality software

• the ability to meet budget and scheduling goals

• improved planning

• the ability to meet quantifiable testing goals
