The method is best applied using worksheets that provide a clear presentation of the data used and aid the processing of the data. Two examples of worksheets are given in Figure 3-1 (Operational Mode) and Figure 3-2 (Non-operational Mode). They are for a hypothetical item using the data listed in Appendix A of this guide.

Note that these examples are shown only for guidance, and are presented separately for clarity in illustrating the detailed method. Other formats could be developed to embrace more than one set of conditions.
