We was watching the demos of
Mantis and
Eventum and discussing which one to use, and the final decision is we're going for Mantis (just 1 vote different). Two major reasons we've selected Mantis are it is easy to use and more easy to setup. Personally I find both options (both also php+mysql) are good and able to meet our requirements. Although Mantis is relatively having fewer features than Eventum, Mantis is fairly simple to use. You don't need any training or user manual before using it and it won't scare you away or confuse you.
Tentatively, everyone in the company will start using it end of this week.
I believe that by using it, we can really track our issues.
Since we've pretty much solved the minor problem of issue tracking, next week we'll see how we can improve our process of using the system.
PS: You can download the
draft proposal here and I'm not so willing to say that we're using WAMP instead of LAMP.
