What is a Six Sigma?

Six Sigma is a business process improvement methodology consisting of 5 steps: Define, Measure, Analyze, Improve and Control. It uses lots of tools and techniques at each of 5 steps to make the exercise of problem solving / process improvement a scientific and breakthrough delivery mechanism. Some of the tools used in define phase are project charter, SIPOC, RACI matrix, voice of customers and GRPI model. Tools used in measure phase are Gage R&R, QFD, measurement system analysis etc. Some of the important tools in analyze phase are value strem mapping, histograms, pareto analysis, fishbone diagrams, root casue analysis, 5 whys, hypothesis testting, regression analysis, ANOVA and so on. Improvement phase tools are brainstorming, benchmarking, PDCA, DFSS, external / internal innovation etc. Analyze phase tools are control charts, mistake proofing, statistical process control charts, risk management, FMEAand process management charts.

Six sigma methodology uses lots of data and statistical analysis to find the root cause of the problem and uses other tools to arrive at best possible solution, implements it with the help of project team ans ensures sustainable benefits from the project. 

Six Sigma objectives are: Reduce defects Reduce cost & cycle time Improve customer satisfaction Improve business performance Methodology to reduce process variation: Input Process Output (IPO) diagram Process Flow (PF) diagram Cause Effect (CE) diagram Standard Operating Procedure (SOP)

Six Sigma is a business process improvement methodology generated by Motorola and GE. Six Sigma will focus on reducing end result variation and to gain more effective result.

Six Sigma = 3 or 4 defects within 1,000,000 process  

Six Sigma objectives are:

1. Reduce defects
2. Reduce cost & cycle time
3. Improve customer satisfaction
4. Improve business performance

Methodology to reduce process variation:

1. Input Process Output (IPO) diagram
2. Process Flow (PF) diagram
3. Cause Effect (CE) diagram
4. Standard Operating Procedure (SOP) 

process improvement technique to eliminate (or) reduce variation in a process.

 

 

Six Sigma as a methodology provides businesses with the tools to improve the capability of their business processes. Six Sigma is a vehicle for strategic change an organizational approach to performance excellence. It is important for business operations because it can be used both to increase top-line growth and also reduce bottom line costs.

 

Six Sigma is a method that provides organizations tools to improve the capability of their business processes. This increase performance and decrease process defect and improvement in profits and quality of products or services. Six Sigma quality is a term generally used to indicate a process is well controlled

It is a statistical Tool to get the efficiency till 99.9%

Six Sigma is a methodology that relies on a collaborative team effort to improve performance by systematically removing waste and reducing variation. It combines lean manufacturing/lean enterprise and Six Sigma to eliminate the eight kinds of waste (muda): Transporting. Inventory. Motion.
