Initial CATTS Cost Effectiveness Tree.

This memorandum documents the development of a cost/effectiveness (C/E) descriptor tree which was developed in support of Operational Tests 1 planning for Device 16A3, Combined Arms Tactical Training Simulator (CATTS). The C/E tree was developed as part of a planned SAFSEA six man-month technical assistance effort to the CATTS Program Director. A C/E tree is a variant of performance descriptor hierarchy methodology in which a taxonomy of measurable system elements is developed down to measurable data elements. A performance descriptor hierarchy considers only system performance elements while a C/E tree considers both performance and cost elements (similar to a Value Model). The 'tree' is designed and constructed to be used as a system evaluation tool. It is an effective evaluation tool because it provides a framework for structuring an evaluation methodology.
