Six Sigma

A six sigma process is the one which produces 99.99966% statistically defect-free outputs which is equivalent to 3.4 defects per million opportunities (DPMO).

What is Six Sigma?

Six Sigma is a data driven, customer focused, and result oriented methodology which uses statistical tools and techniques to systematically eliminate the defects and inefficiencies to improve processes. It is a systematic method to measure and analyze the business processes to identify critical factors affecting business results, thereby improving the processes and establishing controls around the improved processes.
Six sigma is a widely accepted quality concept in the corporate world today. Six Sigma started its journey in the 1980s as a data driven method to reduce variation in electronic manufacturing processes in Motorola Inc. in the USA. Six Sigma became famous when Jack Welch made it vital to his successful business strategy at General Electric in 1995. Today it is used as a business performance improvement methodology all over the world in diverse industry including general manufacturing, construction, banking and finance, healthcare, education, government, KPO/BPO, IT/ Software. At present IT/ ITES sector companies are dynamically implementing Six Sigma and it is no more confined into manufacturing sector
The term ‘six sigma’ comes from statistics and is used in statistical quality control (SQC) which evaluates process capability i.e. the numerical measure of the ability of a process to meet the customer specifications. It was originated from terminology associated with manufacturing which refers the ability of manufacturing process to produce a very high proportion of output within specifications. The sigma rating of a process indicates its yield or percentage of defect-free outputs it produces. A six sigma process is the one which produces 99.99966% statistically defect-free outputs which is equivalent to 3.4 defects per million opportunities (DPMO).
Six sigma uses a set of quality management and statistical methods and creates a team of experts within the organization (Executive Leadership, Champions, Black belt, Green Belt, Yellow Belt etc.) having specific skill sets required to carry out the six sigma project. Each six sigma project carried out within an organization follows a defined sequence of phases with quantifiable value targets e.g. reduction in process cycle time, reduce cost, increase in quality rating/ customer satisfaction index, reduction is defect rate.

Road Map of a Six Sigma project

Road Map of a Six Sigma project:

Identify the areas of improvement
Define the problem statement and goals for improvement in quantifiable terms (i.e. which can be measured numerically)
Determine the resources required for the project
Formulate a project deliverables timeline in a phased manner
Establish performance parameters/ metrics
Gather baseline information about the process
Validate measurement system for the process output (Y)
Examine the data collected in the earlier phase to determine a prioritized list of sources variation
Explore potential causes (potential X’s for causation) and determine the impact of each X has on the response Y
Determine the optimum level of vital few X’s
Validate measurement system for X’s
Verify process improvement
Develop control mechanism to ensure sustenance of the improved process

Some of benefits of Six Sigma are given below:

Six Sigma helps companies to reduce cost and improve productivity
Six Sigma improves quality of projects output by reduction of inefficiencies and defects
Six Sigma increases customer satisfaction, and loyalty
Certified Six Sigma Professionals can help increasing ROI significantly

Six Sigma Quality Ver Traditional Quality

Six Sigma	Traditional Quality
Decisions are driven by data	Decisions are taken based on a combination of data and 'gut feel'.
Control process inputs (Focus on X’s)	Inspection method (Focus on Y)
Structured use of statistical tools to help in problem solving	No formal structure exists for the application of tools
Structured training in applied statistics	Lack of structured training
Root cause approach	Band aid approach
Prevention over inspection	Inspection over prevention
