A set of well-defined and quantifiably justified Measures of Performance (MOPs) is required for the armament and fuel tasks of a Carrier Battle Group (CVBG) as described in the Universal Naval Task List (UNTL). Well-defined MOPs are required because the current UNTL contains MOPs that are not relevant for the Battle Group Commander to effectively evaluate task performance at the CVBG level. These MOPs are incorporated in the CVBG's training plan and provide the Battle Group Commander a method to evaluate the CVBG's level of ability to perform the necessary tasks. This thesis proposes 37MOPs and an application to subjectively evaluate the MOPs to determine which ones are well defined. The application also objectively evaluates the MOPs to determine how well they collectively measure task performance. The proposed MOPs are derived from the task descriptions and objectives found in the UNTL. They are subjectively scrutinized using the twelve criteria required by the UNTL and objectively evaluated using correlation analysis. A simulation is developed for each task to provide the data for the objective analysis. The results indicate that 25 of the 37 proposed MOP's meet the required criteria of being well defined and useful in measuring task performance. Based upon the developed application, it is recommended that the Naval Doctrine Command consider the 25 MOPs for inclusion into its revised UNTL.
