Just-in-time (JIT) manufacturing is a production model focused on timely delivery of products. This study is an attempt to assess the importance of JIT elements in the manufacturing industry of Punjab. A survey was conducted to assess its role in performance improvement, the barriers to implementing JIT, and important benefits achieved after implementation. Various statistical tools like Cronbach's alpha, student t test, correlation and multiple regression were employed. The results demonstrate that JIT approach significantly helps in reducing cost. Continuous improvement approach is helpful in involving people in JIT activities; preventive maintenance and flow layout are rated as most important for improving plant and machinery efficiency; while decisionmaking activities by employees, group technology, and removal of buffer stock are rated least important elements of JIT. The study also found that the biggest barrier to implementing JIT approach is ineffective measurement techniques. Cost reduction is the most important benefit achieved from JIT implementation.


Just-in-time (JIT) manufacturing is a management approach to producing the right product, in right quantity, at right place and at right time. It was introduced by Japan in the 1970s for economic revival post World War II. JIT eliminates waste, controls costs, and is effective in a competitive environment. It is an approach to reducing manufacturing cost, improving flexibility and effectiveness (Gunasekaran and Lyu, 1997). It is a tool to eliminate waste, thus ensuring productivity, quality orientation, cost effectiveness and streamlining of the processes. It helps in simplifying processes, reducing setup time, effective materials flow, preventive maintenance, eliminating excessive inventories and effective use of resources (Kannan and Tan, 2005).

Ohno was the father of JIT and applied it for meeting demand in less time (Fiedler et al., 1993). This technique is focused on system, people, and plants. In this competitive world, manufacturing organizations are focusing on organizational potential, incremental
