Quick Start Introduction This section gets you started with Logical Decisions for Windows (LDW) and points the way to additional information on LDW's more advanced features. It describes the steps needed to evaluate a set of alternatives and the options available at any step. This section is an overview rather than a tutorial, and you will need to review the Tutorial and Using LDW sections to learn the details of the various commands. What Logical Decisions does LDW helps you evaluate alternatives. The alternatives can be anything you need to choose between -- jobs, potential employees, factory locations, or even what wine to have for dinner. LDW lets you systematically look at your alternatives by following a series of steps. The steps help you define and describe your alternatives. They also help you think about the preference and value judgments that you need to make to be able to tell the best alternative from the rest of the alternatives. When you complete the steps you will have a quantitative ranking of your alternatives. You will also be able to review your results with a variety of displays that are specifically designed to help you feel confident that you are making the best choice. The Steps of a Logical Decisions Analysis LDW provides a great deal of flexibility in how you evaluate your alternatives, but you will need to do these basic steps: ! Structure your problem, !
