Limitations of JIT

JIT manufacturing  requires  considerable  co operation between the management  and workers, it  is commonly believed that JIT production system is very efficient  but in due  course of time  many  demerits have been pointed out some of these are :

1. Cultural differences have been  cited as possible  limitation on  JIT. The  benefit  associated with JIT may be  culturally bound and somewhat limited  to Japanese environment.

2. Loss of individual autnomy is another  shortcoming of JIT. Reduced cycle  time  forces  the workers  to adjust  immediately to changes i  demand significantly reducing the  idle time  of the  workers resulting in greater amount of stress and pressure placed upon  the workers to perform.

3. The  success of JIT production  system depends upo co operation between  employer employers daily workstation rotation training of operators for different kinds of jobs and system adaptability  to market function etc.

4. There is no  flexibility  only first come  first served principle is applied by manufacturing  items  in  order of releasing  kanbans.

5. There is no safety stock to off set  inaccurate demand forecasts.

6. JIT  production  is effective  only when  the daily  demands are fairly stable.
