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. This systematic method measures and analyzes the business processes to identify the critical factors that affect business results. Six Sigma improves the processes and establishes necessary 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, companies use it 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 dynamically implement Six Sigma and no longer confined to the manufacturing sector.

The term ‘six sigma’ comes from statistics used in statistical quality control (SQC) which evaluates process capability. Process capability measures the ability of a process to meet the customer's specifications. It originated from terminology associated with manufacturing, which refers to the ability of a 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 equals 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. Target examples include reduction in process cycle time, reduce cost, increase in quality rating/ customer satisfaction index, and reduction in defect rate.

Road Map of a Six Sigma Project:

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

Some of Benefits of Six Sigma:

  • 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 increase ROI significantly.

Six Sigma Versus 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

Six Sigma Methodologies

There are mainly two methodologies of Six Sigma namely DMAIC and DMADV.

DMAIC stands for data-driven Six Sigma methodology that improves existing products and processes. Use the DMAIC process to make an existing product or process meet or exceed the customer’s requirements. DMAIC methodology consists of five phases...

  • Define – Define the project targets and customer (internal and external) deliverables.
  • Measure – Measure the process to determine the current process performance (baseline).
  • Analyze – Find out the root causes of the defects.
  • Improve – Improve the process by eliminating defects.
  • Control – Control the future performance.

DMADV is a common DFSS (Design for Six Sigma) methodology used to develop a process or product which does not exist in the company. DFSS focuses on the design or redesigns of the different processes used in product manufacturing or service delivery by considering the customer needs and expectations. Use DMADV when the existing product or process does not meet the level of customer specification or Six Sigma level even after optimization with or without using DMAICDMADV methodology consists of five phases...

  • DEFINE the project goals and customer deliverables
  • MEASURE the process to determine the current performance level
  • ANALYZE and determine the root causes of the defects
  • DESIGN the process in detail to meet customer needs
  • VALIDATE the design performance and its ability to meet the customer needs
