The XpertUS Decision Support System
The XpertUS Decision Support System [XDSS] consists of three items that makes up the complete suite. These are: Dr. Wirasinghe's book - "The Art of Making Decisions", The Training Course, and The XpertUS Software.

The Book:
This should be your starting point. It will give you a complete insight into decision-making. It is available from any major bookshop. You may also obtain an autographed copy of the book, by sending an email to author@xpertus.com

The Training Course:
Most people have not had any training in decision-making. Sadly many make a mess of some of the decisions they make. If you cannot attend one of our classroom seminars, take the E-Course.

The Software:
The XpertUS decision-maker is a software package developed to handle "qualitative" issues of a problem, and to arrive at the optimum decision.

Volumes have been written on how to handle "quantitative" data in decision-making. This is because the essence of all mathematical theory is "quantitative" analysis. Translating "qualitative" information is extremely difficult and highly "subjective" hence mathematicians tend to steer away from "qualitative" issues. But we have the solution.

We must recognize that even though quantitative data appear to be "factual", "subjectivity" plays a decisive role during the process of obtaining such quantitative data.

XpertUS utilizes several advanced mathematical techniques to translate "qualitative feelings" - into a consistent "quantitative" array that lends itself to a reliable analysis.

We do not issue the software to anyone who has not taken the training course.

Past experience has shown us that anyone who has not taken the course is unlikely to believe the results that the software provides. It is simply a matter of faith. You are not likely to believe something, simply because it spews out a result!
