PREDICTING QUALITY OF AN INFORMATION SYSTEM USING SYSTEM DYNAMICS MODELLING AND MACHINE LEARNING

A method of performing predictive analysis on an external index number describing quality of an information system based on a dynamic causal loop diagram of a plurality of quality meters describing the information system is disclosed. In an aspect, one or more quality meters are selected (402) from the plurality of quality meters for predicting values of an external index number. Values of selected quality meters and the external index number maintained (401) in a database are processed (403) using one or more statistical analysis methods to determine dependencies between the plurality of quality meters and the external index number. Based on the processing, a prediction model for predicting external index number values is established (404). Said model may be trained (406) based on received training data (405) using machine learning tools.
