I once heard this statement from the trainer, during project management training.

After almost 2 years, I recalled this statement - and finally found that it's right.

Back then, I thought that the trainer was joking.

So, technical issue, is only an issue to the project, when:

1) If it's not identified
2) If the person who identify it didn't communicate out to resolve the issue.

It's more like a human factor, after all (which problem isn't really contributed by human, after all?)
