Logical Decisions® is decision support software that helps you evaluate and select the best choice for your most difficult decisions.

Logical Decisions®  is designed for decisions where you need to think about many concerns at once and make judgments about which concerns are most important to you.  View Flyer

A Classic Example

The classic example of this type of problem is buying a car. There are hundreds of possible choices and almost as many considerations you can use to choose between the possibilities — price, mileage, performance, reliability, and attractiveness are just a few.

No one car has it all. Cars with better performance and features cost more. Bigger cars have poorer performance. You have to make tradeoffs and compromises to make a choice. Different people will make different tradeoffs. If they weren’t, everyone would have the same kind of car!

Logical Decisions® helps you make these kinds of decisions effectively. It’s the tool you need to organize information about your choices, to make the value judgments you need to make sure you get what you want, and to display your results so you can get insights into the choices.

 Organizing Your Information

Logical Decisions® combines features from spreadsheet and database programs to organize information about your choices. You can include “hard” data like price or miles per gallon and “soft”, judgmental, information like attractiveness or driving feel. You can import data from spreadsheets or database files.

Logical Decisions® lets you organize your goals and evaluation measures into a structure — like an organization chart — that shows how your individual concerns (like “miles per gallon”) relate to your overall concerns (like “buy the best car”). This powerful feature turns an ordinary data table into a sophisticated hierarchical database that links your detailed information to your broad overall goals. It can turn an incomprehensible mass of numbers into a roadmap that points the way to your best decision.

Making Value Judgments

Value judgments are a crucial part of most decisions. Logical Decisions® draws on tools from an academic discipline called “Multi-Attribute Utility Theory” to help you make the value judgments needed for a particular decision. One type of judgment is the relative importances (weights) of the evaluation measures. Logical Decisions® provides several methods to help you make these judgments, and lets you use the method you are most comfortable with. Logical Decisions® provides 7 different methods for assessing weights, ranging from the easy-to-use “Smarter” method, to the sophisticated “tradeoff” method, to the popular “Analytic Hierarchy Process”.

 Displaying Results

Logical Decisions® provides many results displays designed to give you insights and to make you feel comfortable making a final choice. You can rank your choices from best to worst on any goal or evaluation measure. You can compare pairs of choices to identify their most important differences. You can use charts and interactive displays to see the effect of changes in weights on the overall ranking results. Finally, you can see the effects of uncertainty on the ranking results.
