Road to Success or Failure?

Just-in-Time Systems

Background:


What dictates success or failure for a Just-in-Time system?

As of late we have seen numerous events derail the best efforts of Supply Chains & Just-in-Time inventory systems, to say the least.  In some worst case scenarios we have seen the Supply Chain & inventory systems completely break down.  Some say this will bring about a shift away from Just-in-Time inventory practice to more of a Just-in-Case system or bring back the old notion of safety stocks. 

The performance of a firm's supply chain & especially a firm's Just-in-Time sytem are based on the performance of the larger supply chain & invenotry systems of your suppliers & customers.  The cartoon alludes to this in a comical manner as Dilbert suggests that his customer's success really depends on how well his firm will perform.  With that said here are some questions to ponder:


Questions for Thought:


Why it’s high time to move on from ‘jus...pply chains _ Kim Moody _ The Guardian 1.     Speed has become penultimate in the vast majority of supply chains.  JIT thinking assisted by keeping product moving as quickly as possible.  However, anyone knows that speed brings with it risks.  Can you think of any cases where the speeding up of shipments may have come back to haunt you or a system?

2.     Supply chain managers know the trade-off between managing risk versus managing resiliance.  Managing risk can be defined as the ability to minimize or quickly recover from a disruption whereas managing resiliance is the ability to be prepared for the disruption & weather it overtime.  JIT inventories tend to exacerbate the ability to manage risk & lead to shortages when a crisis erupts.  Resiliance lends itself to bigger stockpiles, more workers, more slack in the system & will assist when the crisis erupts but leads to higher operating costs.  Can you think of an example of a company managing risk versus managing resiliance?

3.     Are their inherent disadvantages to JIT?  What do you think they would be?  What about Just-in-Case &/or higher safety stocks?  How does a firm create a balance?  Or maybe the customer/cosumer must also create a balance?  Your thoughts?
