Public sector automobile rebuild organizations have comparatively low productivity as compared to private sector
organizations especially in developing countries. Despite gigantic budgetary allotments, public sector rebuild organizations
remain non-productive, ineffective and inefficient as they are not exposed to aggressive market competition
and profitability. These organizations are administered by government rules and procedures unlike private sector organizations
which are driven solely on profitability factor. Therefore, conventional productivity improvement models are
as such not fully applicable to public sector rebuild organizations. In this context, data of a public sector automobile
rebuild organization has been collected. Total and partial productivities of the organization have been measured and
analyzed by using Total Productivity Model (TPM). Detailed productivity analysis of the selected organization has
been carried out with specific focus on limitations of model when applied to public sector organizations alongside
reasons for low productivity. Results indicate that public sector organizations need to focus on cost minimization and
resource optimization to enhance productivity and output as compared to private sector organizations which focus
on cost minimization and profit maximization.
