There is not enough time
-too few people to code and test
-not enough room to left them
-must have software in time
It is really not a bug
It is common that we misunderstood that even if there is no error
If we change the user requirements it may results in test errors
It is too risk to fix
As we discussed earlier it's a risk based exercise we can't fix those problems
It's just not worth it
We usually don't consider the bugs that occur infrequently
Bugs that are appeared in infrequently used features
A user can avoid or prevent those bugs.
If there is some problem in the software,but we can't find the bug in the entire software we can't say that its a bug.
One of the advantage in software field is that software can be easily changed we change the code if required
But in other domains it may be impossible
Construct a software that is fair and not copied from any of the other previous systems or softwares.
Competition is high in the software industry
There are so many new technologies that are released everyday in the market.
So that our software should be unique to others to succeed.
