So, I used to think that it would be a good idea to give the customer access to the issue tracking system, but now I've seen that it creates less than ideal situations, like:

• Customer judging progress solely on ticket count
• Developers denied to add issues to avoid customer thinking that there is less progress
• Customer appointing people on their side to add issues who don't always do a good job (lots of duplicate issues, insufficient information to reproduce, and other things that distract people from doing their real job)

However, I think customers should have access to some indicators or proof that there is progress being done, as well as a right to report bugs.

So, what would be the ideal solution to this situation?, specially, getting out of or improving the first situation described?
