Abstract
This paper reports on the development of a parametric cost model that is being built at JPL to estimate costs of future, deep space, robotic science missions. Because of the changes in the mission implementation process and technology changes, the model is being built in a dramatically different manner than past models which have had access to a data base that drew heavily on the correlation between mass and actual costs. Instead, the data base is based on the results of an interdisciplinary team of technical experts that make up the core team that assesses new proposals as they are being planned under the new business process being instituted at JPL. The model is then validated against actual mission costs as the projects are implemented. The discussion will provide a summary of this new process as it relates to the development of the model, some of the details of the model itself, and the status of its validation and plans for the future.
