Lean Six Sigma Overview
Lean Six Sigma Overview Definition Six Sigma is a fact-based, data-driven philosophy of quality improvement that values defect prevention over defect detection (ASQ). Lean The ultimate goal of Lean is to provide perfect value to the customer through a perfect value creation process that has zero waste. The core idea is to maximize customer value while minimizing waste. Simply, lean means creating more value for customers with fewer resources.

Lean Six Sigma Overview Six Sigma as a Business Strategy links the outputs of a company processes to customers requirements. Customer satisfaction can be increased by reducing waste and process variation. This can result in improving operating margins.
Lean Six Sigma Overview Benchmark The Sigma value can be used to Benchmark performance.
Lean Six Sigma Overview Goal The goal of Six Sigma is have the highest level of performance possible. • At the 6 Sigma level there is 3.4 DPMO • 99.9997 % defect free product or service
Lean Six Sigma Overview 6 Sigma 3-5 Sigma 3 Sigma 1-2 Sigma
Lean Six Sigma Overview Methodology Six Sigma as a Methodology, provides a structured, step by step process of assessing and resolving variation in processes which is accomplished completing the following stages: • Define • Measure • Analyze • Improve • Control This process focuses on cause and effect, using numerous analytical problem solving tools, supported by a management structure.
Lean Six Sigma Overview Define “Identify customer requirements” Control “Monitor new processes” Measure “Measure current performance” DMAIC Analyze “Identify root causes for performance defects” Improve “Identify and implement solutions”

Lean Six Sigma Overview Philosophy Six Sigma as a Philosophy is based on the premise that a process will yield a greater return if the variation in process output is reduced to stay within limits defined by the customer. The philosophy is one of continuous improvement, using data and various algorithms to reduce process variation Meeting the customer expectations will realize gain in competitive advantage. There is a positive correlation between Six Sigma Program & Process Performance.
Lean Six Sigma Overview Process measurement As a Process Measurement system, Six Sigma uses data to analyze process performance and find Root Causes of defects. The following calculations are use when assessing defects and root causes: • Defects • Defects per unit (DPU) • Parts per million (PPM) • Defects per million opportunities (DPMO) • Rolled Throughput Yield (RTY) • First Time Yield (FTY) • Sigma Value

Lean Six Sigma Overview Six Sigma as a Project Practical Problem Chronic problem impacting on the success of a process. Six Sigma Project Six Sigma is used to quantify the problem and output expectation. Statistical Problem The quantified problem is evaluated with facts and data analysis
Lean Six Sigma Overview Six Sigma as a Project Statistical Solution Results Data driven solution is found Measurable results with quantifiable financial or strategic value. Control Plan Method is developed for long- term sustainability of the solution Practical Solution Develop ready to implement Practical solution
Lean Six Sigma Overview Six Sigma uses specific tools to solve business problems. These tools are used to map processes, select projects, analyzed data and identify solutions. These tools include but are not limited to: • Pareto Chart • Fishbone diagram • Prioritization Matrix • Histogram • Control Chart • Failure Mode and Effect Analysis • Root Cause Analysis
Lean Six Sigma Overview Process: Sequence of interdependent and linked procedures which, at every stage, consume one or more resources to convert inputs from suppliers into an outputs of value to the customer. Output Input Process Action
Lean Six Sigma Overview Work Process Work Process Output Input Process
Lean Six Sigma Overview Improvement Process Improvement Process Input Process Output
Lean Six Sigma Overview Every process has a dependent variable Y that can be influenced by independent variables Xs. Understanding the relationship between the Xs and Y is the goal of Lean Six Sigma. When this relationship is understood, manipulation of the Xs can be carried out in such a manner so that Y remains within the appropriate range, meeting customer requirements. Y = f(X¹, X², X³ ………….Xⁿ)
Lean Six Sigma Overview Y = f(X¹, X², X³ ………….Xⁿ) Y X
Lean Six Sigma Overview Variation • Lean sigma focuses on variation • All repetitive activities have a certain amount of variation • Variation is the “Voice of the Process” • Input, Process and Output measures have variation.
Lean Six Sigma Overview Critical to Quality (CTQ) A Defects: Service Unacceptable to customer Product or Service Output VARIATION
Lean Six Sigma Overview Sigma σ Sigma is a Greek letter that is used to represent a statistical unit of measurement to define the standard deviation of a population. It measures the variability or spread of the data. It indicates how much of the data falls within the customer’s requirement – the higher the sigma, the more the process outputs, products and services, meet customers’ requirement. The higher the process sigma, the fewer the defects.
