Public sector automobile rebuild industry contributes significantly towards national economy in developing countries. Nonetheless, productivity and output of public sector rebuild organizations remains very low despite huge budgetary disbursements. On the contrary, private sector organizations achieve high productivity and output as these organizations work to maximize their profit. This paper attempts to identify reasons for low productivity and reduced output of public sector automobile rebuild organizations of Pakistan. Input in this research was sought primarily from top, middle and lower management of public sector automobile rebuilt organizations. Data from a total of two hundred and sixty-two respondents representing twenty-one different automobile rebuild organizations was compiled through quantitative survey and analyzed statistically through SPSS. Results implied that public sector automobile rebuild organizations due to certain peculiar characteristics possess low productivity and essentially require a distinct productivity improvement model. Based on the shortcomings/inadequacies identified through literature review, qualitative and quantitative analysis, an inclusive productivity enhancement model for public sector automobile rebuild organizations was reformulated. Proposed model when implemented holistically in rebuild organizations can produce positive results whereas implementation of proposed practices in piecemeal/isolation may not accrue true and optimal outcomes. The findings of this research will facilitate top and middle management to enhance productivity and output of public sector automobile rebuild organizations of developing countries in general and Pakistan in particular.
