VOTING & PROJECT MANAGEMENT modules

Sorry for my Ignorance - But hey I'm a NEWBIE

Can anyone suggest the best all around voting module and project management module

Primarily for stability issues. I dont really see a Project Mod that seems to be complete - but is there something that I might try - I dont need a major PM suite or anything - just some basic features like task assignment - group filtering Etc...

For voting - I'm looking for the MOST stable AND configurable

TIA :-)
