The Quality Assurance Misnomer

Over the years, the industry standard title for a software tester has become “Quality Assurance Analyst/Engineer”. I don’t know the history of this but I do know that it’s not without controversy. When most people in the software industry hear the title, they think of the person’s role as being someone who assures the quality of the software product.  That’s a big problem though because, as a Quality Assurance Engineer myself, that’s not what my job is, nor is it generally the job of any software tester that I know.

Here’s the root of the problem: Quality is a business decision that evaluates whether a product or part thereof is GOOD or BAD and that is a decision that lies in the hands of the product owner – that person which is or represents the product purchaser/user. The reason for this is because they are the person that best knows whether the purchaser/user will be satisfied. Testers don't know the user so it would be presumptuous at best to put that responsibility on them

What I do is I poke, stress, and exercise the software in every way that I can think of and make observations. I compare those observations to documentation and common heuristics that help identify when intended functionality deviates from actual functionality. And then my job is actually to help inform that business decision by reporting all of my observations through conversation, defect reports, and progress reports to the product owner. You see, I can report RIGHT or WRONG based on my comparison to documentation and heuristics but that’s different than GOOD or BAD.

Determining GOOD or BAD is a murky process that is above the pay grade of a lowly software tester and that has to factor in many components including:

• Test coverage
• How stale is the testing (i.e. when was the last time part x was tested?)
• How many failed test cases are outstanding
• What the severity is of the outstanding defects
• Amount of time allowed for planning, developing, and testing
• The gut factor (i.e. does it feel like it’s ready?)

Then taking all of this information, to determine whether the product is GOOD or BAD, you need to have a sense of whether the customer will be satisfied as I mentioned above. The only way to develop this sense is to have an active, direct interaction with the customer from the beginning of the project or to just leave it directly up to the customer. Though, I don’t recommend the latter because without somehow quantifying an acceptance level, they may never agree that the product is good.

All that said, I don’t think that the title “Quality Assurance Analyst/Engineer” is BAD, just misunderstood. While I don’t assure quality through analysis and/or engineering, I do analyze and engineer so that quality can be assured.
