> Software doesn't work like that, it's not singularly done.

This is definitely a business practice problem, and not some intrinsic quality of software.

And even if your business decides that software is never done, nothing stops you from getting a particular build inspected and certified. It's physically possible. The problems are mostly cultural and in other areas: Governments are generally hesitant to regulate business. Software companies lobby extensively to keep it that way. Vendors and customers are generally not willing to pay the increased cost of software inspections. Developers don't like the idea of being held to a quality standard.
