Excellent system, impeccable support team
An excellent system, very recommendable for a project department to keep track of resource effort usage and capacity planning. Useful repository for all project information. The best part about it is the team, who work hard to fix your problems and also incorporate your suggestions into new builds and releases.
Constant revisions and build fixes
Customisable to your needs
Not able to 'plan' projects as well as MS Project - soemtimes you essentially just want a checklist of very small tasks that for part of the plan but are neither a milestone nor large enough to constitue a new code.
If you use the 'costs' part of the system, you would probably want to input this data twice; in Hydra and also in some other budgeting system/spreadsheet as Hydra is not yet sophisticated enough to handle the complexity of a project budget
You need training in Crystal Reports to create your own reports, which you will most likely need
