SIX SIGMA

2. What is Six Sigma ?
• Six Sigma is a quality-control methodology developed in 1986 by Motorola,
Inc.
• Six Sigma is a business system for achieving and sustaining success through
Customer Focus, Process Management, Process Improvement, and the wise
use of Facts and Data.
• It can be used for any activity that is concerned with cost, quality, and
timeliness.
• It can also be used from production, to human resources, to order entry, to
technical support.
• The method uses a data-driven review to limit mistakes or defects in process.

3.  Six Sigma emphasizes cycle-time improvement while at the same time
reducing manufacturing defects to a level of no more than 3.4 occurrences per
million units or events. In other words, the system is a method to work faster
with fewer mistakes.
 It is statistical quality control
 It is methodical approach
 The Customer Focus
 Teamwork Approach to Quality Management

4. Objective
 Overall business improvement
 Remedy defects or variability
 Reduce cost
 Improve cycle time

9. Where can six sigma be applied
 Six sigma can be applied to all organization
1) Design application (Design for six sigma)
2) Manufacturing application ( Operational six sigma)
3) Administrative and service application ( Transactional six sigma)

10. Six Sigma Methodology
• The two main Six Sigma methodologies are DMAIC and DMADV.
• DMAIC is a data-driven method, used to improve existing products or
services for better customer satisfaction. It is the acronym for the five
phases: D – Define, M – Measure, A – Analyse, I – Improve, C – Control.
DMAIC is applied in the manufacturing of a product or delivery of a service.

11. • DMADV is a part of the Design for Six Sigma (DFSS) process, used to design
or redesign different processes of product manufacturing or service delivery.
The five phases of DMADV are: D – Define, M – Measure, A – Analyze, D –
Design, V – Validate. DMADV is employed when existing processes do not
meet customer conditions, even after optimization, or when it is required to
develop new processes. It is executed by Six Sigma Green Belts and Six
Sigma Black Belts and under the supervision of Six Sigma Master Black Belts.
