1 Which Continuous Process Improvement Method Should I Choose? Dr. Reza (Russ) Pirasteh, PMP, MBB, CLM Vice President Operations Excellence Stephen Gould Corporation June 27, 2012 rmpirasteh@stephengould.com ISO All rights reserved 1

2 Objectives Demonstrate the synergetic power of, and when used in logical steps, for continuous process improvement (CPI) Introduce integrated Toc,, (itls) methodology Overview of, Six sigma and Theory Of Constraints () as applied in integrated Toc,, (itls) methodology Overview of comparative analysis of, and itls contributions Overview of the need for itls application, study and history Brief example of typical itls results Overview of itls implementation steps ISO All rights reserved 2

3 Questions Manufacturing companies can produce at least 25% more, why don't they? 25% more projects can be completed in an organization, why aren't they? Despite having 25% more finished goods inventory than needed, why do companies continually lose sales because products are not available to consumers? Bob Fox ISO All rights reserved 3

4 Why? 80% of improvement initiatives fail 70% of company employees do not know the company strategies 73% of strategies are not owned by employees 81% of employees do not feel committed to the organization 92% of employees feel that they are working harder than the year before Over 50% of the work is waste, (Non-Value- Added or Fake Work) Source: Fake Work Gaylan Nielson, 2012 CPI symposium ISO All rights reserved 4

5 Why? Lack of focus on what is the value to end users and consequences Too much Waste and non-value-added activities Too many Errors & lack of consistency in processes, procedures, policies Competing on the edge of chaos Typical rage of waste (COPQ as % of Sales): Manufacturing: 20-30% Services: 30-40% Software: 40-65% ISO All rights reserved 5

6 Alternatives? In past 30 years great management philosophies have been introduced to continuously improve processes and achieve operations excellence by shifting paradigms and challenging the existing assumptions. Over 95% of CPI initiatives are: Theory Of Constraints ISO All rights reserved 6

7 - 7 Muda Toyota Production System (TPS) Focusing on reduction of the seven wastes 1. Overproduction 2. Waiting - People, Parts Overproduction 3. Too Much Inventory 4. Unnecessary Motion Motion Waiting 5. Unnecessary Transporting 6. Over Processing 7. Producing Defects or Rework Rework 6 Intellect Transportation Motion Rework Overproduction Intellect 6 3 Waiting Transportation ISO All rights reserved 7

12 Theory Of Constraints Originated and authored by Dr. Eliyahu M. Goldratt Also referred to as "Constraint Management Focus on Throughput Throughput is what is being sold Rate of revenue generation (Throughput) is limited by at least one constraint Only by increasing capability at the Constraint overall throughput will be increased Focus when dealing with change: Why Change? What to Change? What to Change To? How to cause the change? ISO All rights reserved 12

14 itls Story A Research to Explore How to optimize profits using CPI? There had been little consensus among CPI methodologies Many opinions and guesses Effectiveness: Compare and contrast methodologies Evaluate and statistically quantify the impact Deployment Deploy CPI methodology that yields higher profits Systematic deployment globally ISO All rights reserved 14

15 itls Brief History 1985 Learn and apply TQM Begin to experiment with various combinations of CPI tools Developed TLS CPI model (no consensus) Documented for the first time in the world: Quantified effects of, and TLS 2005 Summarized & documented the designed experiments 2006 Publicized experiment findings APICS 2006 The First CPI Symposium Weber University Introduced itls Scott Jensen 2006 itls-trio model at the Weber University s CPI symposium Decided on writing a book to ensure integrity of itls and possibly bringing the CPI disciplines together for universal betterment Introduced itls-trio model at -ICO (Goldratt - Los Vegas) Others published books based on my research Created the origin of change in models 2010 August Profitability with No Boundaries available Took us 3- years to publish the book we needed to be sure Results of implementations fully supported the model ISO All rights reserved 15

16 itls Story Research Case and had been practiced in for several years Both approaches had shown that they were able to prompt operations personnel to work on a series of projects that resulted in cost savings and process improvements itls: an alternative using synergetic approach ISO All rights reserved 16

17 Experiment Objectives Hypothesized approach to measure and validate effectiveness of: Integrated,, (itls) Analyze results for statistical significance Criteria: Aggregate contribution to verifiable financial savings Validate savings US operations were studied ISO All rights reserved 17

18 Experiment & Approach Methodology was assigned due to the local preference, experience with a particular methodology and expertise Data gathered (Time-years): 2.5 Participating plants: TLS Team leaders trained: 211 Projects completed by all methods: 105 Each site chose their projects and coached with local experts Plant size, population, financial standing were mixed ISO All rights reserved 18
