Using the Shlaer-Mellor object-oriented analysis method

The adaptation of the Shlaer-Mellor object-oriented analysis method for engineering the requirements of a mission-planning system by a missile-guidance software group is discussed. The Shlaer-Mellor object-oriented analysis method provides a structured means of identifying objects within a system by analyzing abstract data types and uses these objects as a basis for building three formal models: information, state, and process. Several issues concerning the application of this method are discussed, including object selection and constraints, modeling and rotation, training, and CASE tool support
