The manipulation logic 746 may vary widely in implementation, and, as one example, may include {TAIL ~ data storage logic} that saves data in memory and {HEAD ~ user interface} logic that accepts capability level specifications, key analysis area specifications, and representative practice data inputs to create new capability analysis structures, modify existing capability analysis structures, delete capability analysis structures, or retrieve capability analysis structures for review
