A system and method for developing and analyzing radiation therapy treatment plans and a computer-generated user interface for presenting data relating to a radiation therapy treatment plan. The user interface includes a list of fractions identified in the treatment plan, data identifying delivery status of the fraction, and data identifying a processing status of the fraction. The system includes a computer processor, a data store connected to the computer processor and storing information relating to at least one fraction of a radiation therapy treatment plan, which fraction has been delivered to a patient as part of the implementation of the radiation therapy treatment plan, and software, stored in a computer readable medium accessible by the computer processor, the software being operable to automatically process the information relating to the at least one fraction.
