Hi all,

Currently we are looking for a tracking system with following featues, kindly let me know what could be the best (or closest) open source system to fit into this requirements.

Workflow for a project that each task needs to go through:
- Loin
- Design
- Testing (if rejected the task need to go back to the Design stage again)
- Quality Assurance (if rejected the task need to go back to the Design stage again)
- Finish

Required model:
- Manager, Team lead, Groups, Client and Admin
- Email, Attachments, Notes, Customized field, Time tracking
- status/task based reporting, hold/query options

Best regards,
Arul

This sounds like project management software. Are you asking about an open source alternative to MS Project? If so, check out Open Workbench
