M131 - Introduction to M130

Introduction

In this module you will learn how the SDBR approach transforms a high inventory, long lead time manufacturing environment into a low inventory, short lead time environment. To do this, we will explore Goldratt's inventory curve and the four key elements of the SDBR approach. We will examine each in detail, understanding what they are and how they are implemented. Additionally, we will explore what happens as each of the four key elements of SDBR are implemented in the plant and how this affects performance.

What you should do

  1. Read the learning objectives carefully.
  2. Watch the video below and make your own notes.
  3. Review the Unit Notes.
  4. Refer back to the learning objectives to ensure you have satisfied each one.
  5. Complete the assignment.

What you should know

At the end of this module you should understand:

  1. What Goldratt's inventory curve is and its characteristics.
  2. The quoted and production lead times and the difference between them.
  3. The choke mechanism and how it reduces the amount of work in process in the plant.
  4. Exactly how the choke mechanism operates in the plant on an ongoing basis.
  5. How the Buffer Management priority system works.
  6. How the buffer status of an individual work order is calculated.
  7. How the buffer priority list of an individual work centre is determined.
  8. How the choke and Buffer Management combine in the early stages of an implementation to drain the plant of inventory.
  9. What happens when the initial choke period ends and the plant begins to release work orders accepted in the choke period.
  10. How a CCR is likely to identify itself.
  11. TOC's Five Focusing Steps.
  12. Twelve tactics to increase capacity at the CCR.
  13. How the Buffer Management process can be used to focus ongoing improvement.
