The TQM Approach•Total quality management= managing the entire organization so that it excels on the dimensions of products and services that are important to the customer. The 3 Key Elements:1.Relentless focus on Customer satisfaction 2.The involvement of all employees3.Philosophy of Continuous Improvement
Principles of TQM - The PDCA Cycle“Shewhart cycle”OR“Deming wheel”Document processCollect and analyze data Develop a planImplement planCollect data for evaluationUsing data to check: results match the goal? Standardize successful method, revise unsuccessful planPlanDoActCheck
Steps in Problem Solving – Six SigmaTheSeven Step Method:1.Select a problem and describe it clearly2.Study the present system/Collect data3.Identify possible causes/Analysis 4.Plan and implement a solution5.Evaluate effects6.Standardize any effective solutions7.Reflect on process; develop future plans
The DMAIC Cycle - Six Sigma Methodology•Define–Project Selection•Measure–Select Characteristics–Define Performance Standards–Validate Measurement System•Analyze–Establish Product Capability–Define Performance Objective–Identify Variation Sources•Improve–Screen Potential Causes–Discover Variable Relationships–Establish Operation Tolerance•Control–Validate Measurement System\Determine Process Capability–Implement Process Control
TQM vs. Six Sigma•Total Quality Management:A philosophy that advocates continuous evaluation and improvement of processes•Six Sigma:An idea that restricts the variance (and increase precision) of the processes.
