Question Description

  • Compare JIT and lean manufacturing approaches to MRP-based planning.
  • Based on your comparison, explain your position on whether the JIT and lean manufacturing approaches are efficient alternatives to MRP-based planning. Justify your reasoning.
  • Evaluate whether these two approaches (the computational approach represented by MRP and the philosophical approach represented by Japanese practices) can be combined to form the ultimate production-planning suite and justify your position.

Manufacturing Approaches




Lean manufacturing is a method which is used for waste minimization in a manufacturing
firm without foregoing productivity. Ideally, what this means is that this process is more
concerned with creating more value for consumers with fewer resources. An organization that
embraces lean often understands customer value and focuses its operations in a way that the
operations increase consumer value (Stevenson & Hojati, 2007). The ultimate goal of lean is to
create a perfect value to consumers with zero waste. JIT stands for Just In Time. It is an
inventory approach that firms use to expand effectiveness as well as minimize waste through
getting products when there is demand in the process of production. As a result, this reduces
inventory costs. This approach requires producers to be able to predict demand accurately. MRP
means material requirements planning. This is...
