Has anyone ever released a major build of software that was perfect?

And what exactly is wrong with an "ad hominem" argument? Dodgy Agent, 16-5-2014 -
It's near impossible for a group of BAs to think of every permutation that a large user group will.
It's near impossible for a group of SAs to think of every permutation that a large user group will.
It's near impossible for a group of Developers to think of every permutation that a large user group will.
It's near impossible for a group of testers to simulate every permutation that a large user group will.
Hence bugs.Comment

It sometimes leads to interesting (actually rather tiresome) discussions after a system has been tested and then users are faced with issues. One of the things I always try to do when taking on a testing project is to manage the expectations of the clientco. Some clients think that if software is tested there is no possible excuse for bugs being found in production. I try to explain to them beforehand that testing can never prove the absence of bugs, but can only demonstrate the presence of those bugs that can be found using the test cases that are prepared, and that the accuracy of any statement about a system’s quality is related to the specific configuration of software and hardware on which it is tested. Testing is also a time and budget constrained activity, just like development or analysis; give us 2000 years, an unlimited budget and a frozen configuration and we might be able to test every possible path through a very simple piece of software that automatically sends cards to people their birthday. Still, we can’t guarantee the OS or the hardware config.
One loud American CFO once threatened me and his software supplier with legal action if any bugs at all were found after taking a system into production. Both the project manager and I then told him that he had two options;
- never take the system into production, or
- accept our resignation immediately
He then took advice from his legal staff and came back with a more reasonable proposal and a somewhat grumpy look on his face.And what exactly is wrong with an "ad hominem" argument? Dodgy Agent, 16-5-2014Comment

Of course it helps to have good BAs who leave no ambiguity in the BRD. So a QA team should always test the docs before the system.Comment

All my software does exactly what I told it to do, so by that measure is perfect.
Whether I programmed it to do the right thing or not is a different issue. It's not its fault that I'm not perfect.Will work inside IR35. Or for food.Comment

Everything that comes out of Cupertino is perfect.
If you want to prove that your software is perfect, you could always try specifying it in Z.Comment

The most common way of getting your software perfect, is to define it as perfect, regardless of how borked it is. Sorted.Comment
