Software Development Cycle
Software doesn't just appear on the shelves by magic. That program, shrink-wrapped inside the box along with the indecipherable manual and 12-paragraph disclaimer notice, actually came to you by way of an elaborate path through the most rigid quality control on the planet. Here, shared for the first time with the general public, are the inside details of the program development cycle.
1. Programmer produces code he believes is bug-free.
2. Product is tested. 20 bugs are found.
3. Programmer fixes 10 of the bugs and explains to the testing department that the other 10 aren't really bugs.
4. Testing department finds that five of the fixes didn't work and discovers 15 new bugs.
