Involvement of Just In Time JIT
[attachment=16377]
Introduction
Just-in-time is an inventory system where raw materials are delivered right before they are needed on the assembly line, and finished goods are manufactured just before they are shipped to customers.
Just-in-time improves return on investment by substantially reducing overhead cost, limiting quality inspections, and eliminating obsolete inventory.
Under just-in-time systems, production stops when parts aren't delivered on schedule, and huge bottlenecks are created when product isn't shipped on schedule.
Successful just-in-time manufacturing requires both superior management and a highly disciplined workforce.
Just-in-time is closely associated with methods introduced and refined by the Toyota Motor Company of Japan and copied by manufacturers throughout the world which attempts to eradicate waste of all kind
The benefits of JIT are:
-Better quality products
-Quality the responsibility of every worker, not just quality control --inspectors
-Reduced scrap and rework
-Reduced cycle times
-Lower setup times
-Smoother production flow
-Less inventory, of raw materials, work-in-progress and finished goods
-Cost savings
-Higher productivity
-Higher worker participation
-More skilled workforce, able and wiling to switch roles
-Reduced space requirements
-Improved relationships with suppliers
Employee Involvement in JIT
One of the important concepts of TQM is employee involvement. This is a relatively new method, which is a contrast to conventional management practices, wherein management takes all decisions and workers just follow them to accomplish their jobs. This top-down management style is slow and inflexible with little room for competition. Survival in today s time-starved, customer driven market requires rapid response times from manufacturers and other businesses to the ever-changing customer needs.
