Chapter 3: The Tool 19 3.7 Worksheet 6, Cost-Util & Strengths After cost data have been updated for GSMs on the short list, cost per util is calculated in Work- sheet 6 (shown in Figure 7). The user can sort Cells A11 to M112 in this worksheet in descend- ing order in Column H (cost per util) to further prioritize the short list, with the lowest cost per util suggesting the largest security improvement per dollar. Selection of candidate security measures should not be based solely on these sorts. The user should carefully assess strengths and weaknesses of the security measures (Columns J and K) and add additional information as needed (Column L). Further consideration of strengths, weak- nesses, variations, and costs may be needed. Suppliers should be contacted for specific informa- tion, product demonstrations, and on-site equipment trials. Other organizations should also be consulted regarding selection of the final options, particularly the U.S. Coast Guard and Captain of the Port, local law enforcement, and security experts. Changes should be made to GSM description or characterization (Columns A through E) based on this further research, which can be entered in Worksheet 3, Characterization. This may also cause changes in applicability ranks, which should be edited in Worksheet 4, Applicability Ranks, and changes in costs data should be made in Worksheet 5, Costs.
