Abstract: Continuous changes and improvements in new product development and its process have brought competition to its peak among the manufacturing sector firms. Incessant improvement considers as the only option for sustainable development and growth. The new products have been launched by firms at regular interval of time to stay updated with present market trends and followings. Recognising current status of the firm with respect to its competitors is of utmost importance for better strategy formulation and decision making. In this study electronics, garment and metal and machinery industries are chosen for an in-depth analysis because of enormous growth shown by them in past few years. The firms are categorised into three classes termed as innovative, mediocre and traditional on the basis of their new product growth rate (NPGR). Adaptive exponential functional linked artificial neural network (AEFLANN) along with other neural network models and conventional methods of classification has been employed. An extension of AEFLANN model using derivative-based (RLS) and derivative free (PSO) algorithm has been proposed. Comparative performance analysis for neural network and conventional classification algorithms has been made. Neural network classification models outperform other employed models in terms of classification accuracy.
