Objectives: The aim of this paper is to closely examine and the study the dimension of Marketing orientation on Performance of Self Help Groups (SHGs) and to establish a relationship if any between these two vital constructs. Method and Statistical Analysis: The paper has adopted a cross sectional design and uses basic inferential statistical tools like t-test and ANOVA to confirm the set hypothesis. Survey method was followed to capture data from 132 SHGs belonging to two clusters in the Cuddalore Dist, Tamil Nadu. The paper provides empirical insights into the functioning of SHGs at present and the need for Market orientation, in the absence of which makes SHGs unsustainable. Findings: The evidences show clearly SHGs that have market orientation have revealed better performance. Therefore we are able to establish a positive relationship between market orientation and performance the SHGs. Rope making and doll making are two clusters we considered for data capturing. It was found that both the clusters respond differently to the dimensions of market orientation and business performance. It could possibly be due to the sophistication of their endeavours. Doll making activity compared to rope making require more skills and investment. Hence, there is a significant difference in the performance levels and their attitude towards market orientation of the two clusters. Application /Improvements: The research indicates the emphasis to be laid on market orientation to improve performance. In the age of web technologies, SHGs can look at digital environment on the web as another channel that can improve their sales bottom lines. © Serials Publications Pvt. Ltd.
