A Little More History Juran and Deming
Lean Roots are in Total Quality Management (TQM) Total Quality Management and continuous improvement Bell Telephone employee and Professor Walter Shewhart. W. Edwards Deming – attributed with saving the Japanese economy after WWII Joseph Juran Also traveled to Japan Quality Control Handbook 1962, updated Not to be reprinted without the expressed written permission by SSD Global, Inc.

Both Believed Quality means conformance to requirements, not goodness Quality is achieved by prevention, not appraisal Quality has a performance standard of Zero Defects, not acceptable quality levels Quality is measured by the Price of Nonconformance, not indexes 4Not to be reprinted without the expressed written permission by SSD Global, Inc.

SSD Global 8 Wastes (Lean) T - Transport - Moving people, products & information I - Inventory - Storing parts, pieces, documentation ahead of requirements M - Motion - Bending, turning, reaching, lifting W - Waiting - For parts, information, instructions, equipment O - Over production - Making more than is IMMEDIATELY required O - Over processing - Tighter tolerances or higher grade materials than are necessary D - Defects - Rework, scrap, incorrect documentation S - Skills - Under utilizing capabilities, delegating tasks with inadequate training
SSD Global 8 D is Short for Eight Disciplines D#1 - Establish the Team D#2 - Describe the problem. D#3 - Develop an Interim Containment Action D#4 - Define / Verify Root Cause D#5 - Choose / Verify Permanent Corrective Action D#6 - Implement / Validate Permanent Corrective Action D#7 - Prevent Recurrence D#8 - Recognize the Team
Theory of Constraints Overview
Theory of Constraints Management Philosophy Eliyahu Goldratt Book: The Goal 1992, but revised Talks a lot about Win-Win Team Building Empowerment and Delegation In That Way Very Lean Friendly Book: The Theory of Constraints
TOC Approach Identify the Constraint Focus on the Constraint Follow it Through (On-going Improvement) Sometimes called Constraint Management Basically the philosophy supports a way of handling constraints
Theory of Constraints Thinking Process Gain agreement on the problem Gain agreement on the direction for a solution Gain agreement that the solution solves the problem Agree to overcome any potential negative ramifications Agree to overcome any obstacles to implementation

“ Every real system, such as a business, must have within it at least one constraint. If this were not the case then the system could produce unlimited amounts of whatever it was striving for, profit in the case of a business.……………….” PREMISE
Types of Constraints THE MARKET CAPACITY RESOURCES SUPPLIERS FINANCE KNOWLEDGE OR COMPETENCE POLICY
The Five Steps Step 1:Identify the system's constraint(s) Step 2:Decide how to exploit the system’s constraint(s) Step 3:Subordinate everything else to the above decision Step 4:Elevate the system’s constraint(s) Step 5:If in the previous step, a constraint has been broken go back to step 1, but do not allow inertia to become the system’s constraint Inertia is the resistance of an object to a change in its state of motion
