Dear NITIN GROVER ! The goal of Six Sigma is to increase profits by eliminating variability, defects and waste that undermine customer loyalty. Six Sigma can be understood/perceived at three levels: Metric: 3.4 Defects Per Million Opportunities. DPMO allows you to take complexity of product/process into account. Rule of thumb is to consider at least three opportunities for a physical part/component - one for form, one for fit and one for function, in absence of better considerations. Also you want to be Six Sigma in the Critical to Quality characteristics and not the whole unit/characteristics. Methodology: DMAIC/DFSS structured problem solving roadmap and tools. Philosophy: Reduce variation in your business and take customer-focused, data driven decisions. Six Sigma is a methodology that provides businesses with the tools to improve the capability of their business processes. This increase in performance and decrease in process variation leads to defect reduction and vast improvement in profits, employee morale and quality of product.

Hai, Six Sigma is a system of practices originally developed to systematically improve processes by eliminating defects. Defects are defined as units that are not members of the intended population. Since it was originally developed, Six Sigma has become an element of many Total Quality Management (TQM) initiatives. Key Concepts of Six Sigma, * Critical to Quality: Attributes most important to the customer * Defect: Failing to deliver what the customer wants * Process Capability: What your process can deliver * Variation: What the customer sees and feels * Stable Operations: Ensuring consistent, predictable processes to improve what the customer sees and feels * Design for Six Sigma: Designing to meet customer needs and process capability
