Five-Step, Continuous Process emphasizing acting locally Five-Step, Continuous Process emphasizing thinking globally Time Both can achieve immediate results, but require a long term about five year effort to sustain the results Combining Lean Thinking with the Theory of Constraints Can the Theory of Constraints be used as a catalyst for lean implementation?
What is this thing called Theory of Constraints and how should it be implemented? Summary by James R. The book includes two main parts and two appendices.
How Should it be implemented? What is this thing called the Theory of Constraints Part I includes four chapters: In Chapter 1, Goldratt builds on the two major questions above by describing the five focusing steps listed below.
In Chapter 2, he discusses the process of change, resistance to change, and how to overcome the resistance to change. The Effect-Cause-Effect method for identifying constraints is discussed in Chapter 3 and the Evaporating Cloud method of inventing simple solutions is explained in Chapter 4. These ideas are sketched out in the table below and discussed more fully following the table.
Identify the system's constraints. Use the Effect-Cause-Effect method to identify constraints. Decide how to exploit the system's constraints. What to change to? Use the Evaporating Cloud method to invent simple solutions.
Subordinate everything else to the above decision. How to overcome the emotional resistance to change. Use the Socratic method to induce people to invent solutions.
The Socratic approach reduces or eliminates the emotional resistance to change and allows the inventor to take ownership of the idea. Elevate the system's constraints. If a constraint has been broken, go back to step 1, but do not allow inertia to cause a system's constraint. The Process of Change The Socratic Method Any change is perceived by some as a threat, so a method is needed to overcome the emotional resistance to change with a stronger emotion.
The Socratic method is discussed as a way to overcome resistance to change. Using this approach involves asking questions that help a person invent their own solutions.
According to Goldratt, when you provide a person with the answers, you block them from the opportunity of inventing the answers for themselves and create emotional resistance to acceptance and implementation. In The Goal, Jonah the consultant who appears to have all the answers asks Alex the plant manager with the problems a series of questions, but does not provide the answers.
Alex struggles with the questions but eventually discovers the answers and internalizes the whole concept of TOC in the process. By inventing their own solutions, Alex and his employees take ownership of the concepts.
How to Prove Effect-Cause-Effect Goldratt defines the effect-cause-effect method as the process of speculating a cause for a given effect hypothesis and then predicting other effects from the same cause. Verifying each predicted effect builds a logical tree and provides a powerful way to determine core problems.
An example is provided from Chapter 4 of The Goal that combines the Socratic and effect-cause-effect methods. Alex meets Jonah, by chance in an airport between flights. Jonah asks "Was your plant able to ship even one more product per day as a result of what happened in the departments where the robots were installed?
Jonah continues, "Come on, be honest, your inventories are going through the roof, are they not? And everything is late, you can't ship anything on time. Walking towards the gate to board a plane, Jonah continues, "You think you are running an efficient plant Jonah tells Alex that productivity is meaningless unless you know what your goal is.
Alex responds that his companies goal is to increase efficiencies. Jonah says, "Your problem is you don't know what your goal is. You can find the answer with your own mind. How to Invent Simple Solutions with the Evaporating Clouds Method The evaporating clouds method is described in Chapter 4 and involves examining the foundations of the system.
The idea is to find the minimum number of changes that are needed to create an environment where the core problem big black cloud cannot exist. You do not try to solve the problem, but instead cause the problem not to exist.The Theory of Constraints (TOC) is a philosophy developed by Dr. Eliyahu M.
