Figure 6-18. Measure Category Dialog Box. Printing Evaluation Forms The Assess::Evaluation Form option lets you generate a form that you can use to evaluate alternatives. When you select the option, LDW generates a form similar to that shown in Figure 6-19. 6-32 Section 6 -- Using LDW 1: Structuring
Figure 6-19. Example evaluation form. You can print the form out directly from logical decisions or save it as a .doc or other text format file and then use it to collect data for your alternatives. Section 6 -- Using LDW 1: Structuring 6-33
