<P>Role of a Software Quality Assurance Group</font>
</center></P>
<font size=2 face="Comic Sans MS">
<P>In working with dozens of companies, I've had the opportunity to see
how different organizations view the role of Software Quality Assurance
(SQA). At one end of the spectrum is the SQA Group that has both the
authority and reputation for not letting anything out the door that isn't
as close to perfect as possible - even though customers are willing to
accept something less.
<p>
At the other end of the spectrun is the organization that uses its
Technical Support Group as a surrogate SQA group. The support staff are
responsible for testing the software prior to release but yet have not
had the benefit of any training in how to test. As a result, many bugs
slip through causing undue frustration for both customers and the
Technical Support staff. And there are many variations between these two
extremes.</P>
<p>
The one thing that these two extremes have in common though, is that in
both groups, the staff is focused solely on testing. What we should have
learned by now is that the sooner we find a problem, the easier and less
expensive it is to fix. We should also know that inspections are much
more effective at finding defects than testing. Organizations need to be
performing inspections of requirements, designs, code, and tests
throughout the development process in order to help find problems sooner
rather than later. Clearly, this is an area where SQA can play an active
role.
<P>
As a result of the lack of consistency in how SQA is performed,
Software Quality professionals frequently find themselves faced with the
dilemma of "How good is good enough and when should the product be
released?" Frequently, requirements for quality are not specified and SQA
may not be aware of what customers were promised or are willing to
accept. As a result, SQA is often caught between rock and a hard
place. Do we release a product with known defects or do we continue
testing...</P>
<P>In my opinion, it's not reasonable to put SQA in the position of
making the release decision. I've found from years of experience, that
SQA should provide information to Management so that <I>they</I> can make
the release decision. Sometimes Management will agree with SQA, sometimes
they won't - and that's perfectly reasonable. As professionals, SQA
people need to recognize that this is a better role to play.</P>
