Bug tracking system is the first step in implementing quality controll system in the company especialy when there are a lot of  web aplications which are critical for the co. There are many tools which may be used for that purpose but I chose Bugzilla which is free, open source software for Linux platform ( Mysql + PHP ).

You can add there Projects and Components of the projects with person assigned to the bug by default. Maybe the software is not user friendly but it works good. You can report bug with few clicks and bug goes to the responsible person with email notifications.

There are many advanced options which dont need to be used like voting ( which bug should be fixed first ), software versions, etc. I focused on main funcionality - reporting bugs.

The other thing is to make routine in the company to report bugs...Usualy people dont care about the bugs which realy annoyes me. The best way is to pay bonuses for the people who report the most critical bugs. It works for most of the staff...however this system improved our web applications a lot.  Maybe some day I will add more procedures based on that system...
