The IT services industry is playing an active role in the Indian economy, contributing to significant new employment generation and exports from the country. The rapid strides made by the industry and its comparatively better performance with respect to the other sectors of the economy, has attracted the attention of researchers in the recent past. However, there exists a gap in the empirical work pertaining to the Indian domestic software industry, especially with regards to firm performance. This study attempts to fill this gap, looking at the issues empirically and focusing on IT services firm performance instead of industry performance. This book is concerned with the performance measurement to appraise the efficiency, effectiveness and performance using a sample of 40 Indian Domestic Software firms operating in India by using CCR and BCC Models in a two-stage performance evaluation model.
