Software Quality Assurance (SQA) and Structured Software Testing (SST) are completely different fields. Every single book on the topic (textbooks, course materials, you name it) make this clear. In fact, most emphasize how important it is that these fields be completely separate. Consider:
Quality Assurance is responsible for auditing and ensuring all aspects of work meet [...]
Management tools probably don’t bring to mind excitement and visions of “getting things done” the agile way. Nevertheless, it’s an important aspect of running any project — whether agile or not — and there are some tools, believe it or not, that are easy to use, hugely helpful in managing a project and sometimes even [...]
Testing, testing, testing. In a recent article by John Parkinson (Strong Signals, CIO Insight magazine) the value of testing is raised on par with the activity of design and coding itself:
Testing is becoming as necessary a profession as design and coding. Skills and experience matter. Process matters. Tools matter. Let the tests begin.
Our systems are [...]
The price of software problems is very high: As much as 50% of development and 100% of all maintenance costs can be attributed to software defects. Often, this price becomes apparent late in the software life cycle—quite often after the software has reached its operational phase (after the software ships)—as previously undetected defects are discovered [...]
Managing software quality is not simply creating a test program during a late-phase testing period. In fact, addressing quality assurance in this way is too little, too late. This far into the software life cycle, defects have become an intrinsic part of the architecture.
