Abstract: In a modern organisation, it is crucial and common for managers to effectively detect the impact of Information Technology (IT) on firm performance. This allows companies to maintain a competitive edge in rapidly changing business environments and outperform the competitors in the global marketplace. To detect the impact of IT on firm performance, this paper presents a generic model using Data Envelopment Analysis (DEA) and Decision Trees (DTs). The model consists of two modules: module 1 applies a two-stage DEA and classifies the IT-affected Decision Making Units (DMUs) into efficient and inefficient clusters based on the resulting efficiency scores. Module 2 utilises firm performance related data to train DT model and apply the trained DT model to new firms. Our results yield a favourable classification accuracy rate.
Keywords: information technology; IT impact; data envelopment analysis; DEA; decision tree; classification; firm performance; organisational performance; decison making.
