A software business is made when someone needs an automated computation and buys a program from someone else.

The buyer has a specific requirement, which is distilled into a specification. The specification is implemented. Implementation that doesn't match with the specification is a bug.

Now in order to verify the implementation's correctness relative to the specification there must be a QA.

The idea that people forgets to add QA in the software development process is wild because it means people are forgetting how to conduct business.
