We support Student Information Software for 20+ school districts.  We have a Software support team who determines customizations to make to the software.  And we have a development team that makes programming changes to the software and creates new reports, screens, and database changes.  Is anyone else using IIQ for software development?  If so, what is the best way to send tickets through the phases of software development?  (Analysis, Design, Testing, and Implementation)  

We are looking into subtasks and subtickets.  What are others in the community doing for software  change support.
