SCHEDULING APPLICATION ALLOWING FREEFORM DATA ENTRY

A project management application provides an environment in which a user can transform a project sketch, which is based on mostly "freeform" data, into a defined project plan. The project management application facilitates the mixture of freeform task attribute values with structured attribute values of one or more project tasks. The project management application can utilize an internal calculation model to manage the relationships between task attribute values despite accepting freeform values for task attributes. The project management application calculates the attribute values to the extent allowed by the calculation model's recognition of the attribute values.
