THEORY OF CONSTRAINTS HANDBOOK, CHAPTER 15 –
CONTINUOUS IMPROVEMENT AND AUDITING THE TOC WAY

In this chapter of the Theory of Constraints Handbook, author, Dr. Alan Barnard shares his research insights on why so many of the changes initiated by management fail to deliver the desired improvement (typically 70% of all changes fail) and how Theory of Constraints can be used to significantly reduce this failure rate. To answer these two important questions, this chapter provides a framework for designing and implementing a continuous improvement and auditing process within organizations from a Theory of Constraints (TOC) perspective and shares some of the important new TOC developments in this field as well as make recommendations on practical ways to integrate this approach with organizational strategy and as a focusing method for LEAN, 6 Sigma and other improvement techniques.

The chapter starts with the definition of key concepts and a brief historical perspective on this subject and then provides an overview of the current gap and its and consequences related to typical errors of omission, commission, detection (to answer Why Change). It then examines the underlying conflicts and assumptions that need to be challenged (to answer What To Change), the solution criteria, direction and details of a solution to break these conflicts and prevent new undesirable effects (to answer What To Change To), and finally sharing insights on how to practically overcome typical implementation obstacles (to answer How To Cause The Change and Achieve a Process of Ongoing Improvement).

THEORY OF CONSTRAINTS HANDBOOK, CHAPTER 16 –
HOLISTIC THEORY OF CONSTRAINTS IMPLEMENTATION CASE STUDIES

In this chapter of the Theory of Constraints Handbook, authors, Dr. Alan Barnard and Ray Immelman shares their experience and research insights on how to put a whole organization (not just Operations, or Distribution or Engineering or Sales) on a Holistic Process of Ongoing Improvement (POOGI) where all changes are focused and synchronized to achieve both ongoing growth, harmony and stability.

This chapter provides a historical perspective on the need for an holistic approach to implementing Theory of Constraints (TOC), an overview of the past attempts to develop such an approach and why most of these attempts have failed. Then two of the leading TOC experts in the world (Dr. Alan Barnard and Ray Immelman), each with many TOC implementations behind them, share their unique experiences and insights gained on how to achieve and sustain a holistic TOC implementation that will deliver both ongoing performance growth and improved stability and harmony through two large and complex TOC case studies – one from the Private Sector (First Solar Inc.) and one from the Public Sector (Solid Waste Management in African Cities).
