Question - What Is Difference Between Lean Manufacturing And Jit (just In Time)? 
          
        
        Answer - 
        
Lean Manufacturing:  It takes the concept of JIT and re-examines it from the customer point of view.  Anything that is produced should add something of valuable to the customer’s requirement. For example, if you are making stereo system for a luxury car, you will think from the customer point of view like sound quality, durability, space occupancy, loud or medium sound, etc.
JIT (Just-in-Time):  This methodology is designed to ensure that a product or part would arrive just in time to be used. This technique saves the cost behind the unused inventory, and eliminating the need of piling up inventory.
