Qualitative operational risk software -development of a software tool for determining the root of operational risk

摘要

This article shows software that allows determining the statistical behavior of qualitative data originating surveys previously transformed with a Likert’s scale to quantitative data. The main intention is offer to users a useful tool to know statistics' characteristics and forecasts of financial risks in a fast and simple way. Additionally,this paper presents the definition of operational risk. On the other hand, the article explains different techniques to do surveys with a Likert’s scale (Avila, 2008) to udknow expert’s opinion with the transformation of qualitative data to quantitative data. In addition, this paper will show how is very easy to distinguish an expert’s opinion udrelated to risk, but when users have a lot of surveys and matrices is very difficult to obtain results because is necessary to compare common data. On the other hand,udstatistical value representative must be extracted from common data to get weight of each risk. In the end, this article exposes the development of “Qualitative udOperational Risk Software” or QORS by its acronym, which has been designed to determine the root of risks in organizations and its value at operational risk OpVaR ud(Jorion, 2008; Chernobai et al, 2008) when input data comes from expert’s opinion and their associated matrices.
