The History of Lean Six Sigma A New Approach to Quality
History of Lean Six Sigma What is in a name? Lean -- Focuses on removing waste (muda) from processes Six Sigma Focuses on understanding and reducing variation in processes Lean Six Sigma (LSS) Combines both approaches What is the Concept behind LSS? As wasteful activities are removed overall process variation is reduced Lean Six Sigma is one of many methodologies developed through the Quality Revolution
HistoryEvolution of Quality Craft Production Each item is unique Individual parts made to fit Quality through craftsmanship Mass Production High volume Interchangeable parts Quality through inspection Better Production Understanding of process variation Quality through process
Evolution of Quality--Timeline 1798 1920s 1950 1960 1980 Statistical Process Control Toyoda Production System Reconstruction of Japan Interchangeable Parts Six Sigma Eli Whitney Walter Shewhart Deming & Juran Eiji Toyoda Motorola
Expanding Application of LSS Initially applied in production environments Manufacturing Supply Chain Maintenance Repair and Overhaul (MRO) Rapidly grew into transactional applications Financial Institutions Insurers Continued to expand to services Hospitals and Health Care
A Couple of Questions What does Six Sigma mean? A process that has a six sigma level of quality experiences only three defects per one million opportunities. Is it Important to have a six sigma level of quality? It depends on the customers perception of quality. If you are landing airplanes, it is critical to obtain at least a six sigma level of quality. If you are manufacturing coffee stirrers, lower levels of quality may be completely acceptable. 1. a. 2. a) Sigma Level 6 Sigma 5 Sigma 4 Sigma 3 Sigma 2 Sigma 1 Sigma DPMO 3.4 233 6210 66,810 308,770 697,672

Lean Six Sigma Methodology What is Lean Six Sigma?
LSS Methodology DMAIC Process Key Concepts Understanding Variation Voice of the Customer Voice of the Process LSS Organizational Roles Champion Master Black Belt Black Belt Green Belt Yellow Belt
DMAIC Process What is the problem? What is the goal? Define What is the current performance? What is the defect rate? Measure What are the sources of process variation? What are the root causes of defects? Analyze How do we change the process? How do we verify our changes will improve the process? Improve Are the improvements to the process consistent over time? How do we maintain the improvement into the future? Control
Key Concepts of LSS Understanding of Variation Two types of variation Controlled variation (Common Causes) Uncontrolled variation (Assignable/Special Causes) Improvement strategy based on type of variation Controlled variation = Change the process Uncontrolled variation = Deal with the special events Voice of the Customer (VOC) How does the customer describe quality What is the customers tolerance for defects VOC is often expressed as specification limits Goals should align with the voice of the customer
Key Concepts of LSS Voice of the Process (VOP) What is the current process capability How much variation is in the process How many defects does it produce What is the process average What process inputs are important to final quality Conceptual Summary of Lean Six Sigma Y= (x) The Output (Y) is a function ( ) of the inputs (x)

Lean Six Sigma Success Factors What are the building blocks for successful LSS programs?
Considerations for LSS Success Organizational Factors Commitment of Senior Management Clear organizational vision and goals Effective LSS training strategy LSS Team Factors Flexibility Practicality Focus on Customers (Internal and external) Strengths of LSS Methodology Data Based Scalable Structured
Considerations for LSS Success LSS Challenges It is not a quick win approach to continuous improvement It requires an investment It requires a degree of organizational humility
Applying LSS in Human Resources Can I apply LSS to my processes?
Questions for Consideration You have mentioned that LSS is an organizational approach. Can I learn LSS concepts and apply them to my area of expertise? What are the challenges faced when trying to apply LSS to HR processes when the larger organization hasn t embraced the methodology? What are the unique challenges for HR in the application of LSS? What types of process are idea for LSS application? 1. 2. 3. 4.
Effective LSS Application In HR A Case Study: The New York Independent Operator (NYISO)
NYISO Success Factors Well-defined corporate mission and goals Executive commitment to LSS Established infrastructure to support LSS Systematic approach to LSS training Focus on core processes (affecting multiple value streams) Supportive corporate goal structure
Background -- The Roles of the NYISO Reliable operation of the bulk electricity grid Managing the flow of power nearly 11,000 circuit-miles of transmission lines from more than 300 generating units Administration of open and competitive wholesale electricity markets Bringing together buyers and sellers of energy and related products and services Planning for New York s energy future Assessing needs over a 10-year horizon and evaluating the feasibility of projects proposed to meet those needs Advancing the technological infrastructure of the electric system Developing and deploying information technology and tools to make the grid smarter
Case Study Project Title: Reduce Cycle Time to Hire for Open Positions Problem Project baseline data reviewed from November of 05 to November of 06 Average cycle time to hire was 70 days (Median = 43 days) Standard deviation was 70 days 57 percent of positions filled within 60 days Goal Fill open positions in 60 days or less 90 percent of the time Result 87 percent of positions were being filled in 60 days or less (2007)
Overview of Improvements Defined and communicated HR Hiring Process / Roles to NYISO Management Implemented Kick-Off Meetings for all Openings: Review/Define Job Specs and Posting information Discuss salary range and position level Discuss Pre-Screening questions and timing Discuss Recruiting strategy Review Hiring Process and HR/Hiring Manager Roles Standardized Pre-Screening process and questions Developed standard interview format, questions, evaluation Created dashboards for HR management and Senior Team reporting
Controls Overview Process Step Strategy Session Control Activity Requisition signed by HR and Hiring Manager before recruiting begins Legal Review for Fair Labor Standards Act ramifications Hiring Manager review / signoff before posting Generalists secure approval signoff from Management and HR Job Description Changes Job Posting Preparation Offer Preparation
