I like how it can be used in conjunction with other tools to help keep track of projects for different teams or departments.
It's easy enough to learn if you're familiar with MS Project but not everyone has this knowledge so there could be some confusion when using certain features as well. The software does have an excellent user interface which makes learning very simple. If your looking into project management then definitely give prodigy a try - helps manage multiple tasks by assigning them to team members who are responsible for those particular areas!
