Six Sigma

Six Sigma is the measure of quality that strives for near perfection.

It is a disciplined, data-driven methodology focused on eliminating defects.

Six Sigma is a reference to a statistical

measuring system, equivalent to just 3.4 defects per every million opportunities

Conceptually◦ Program designed to reduce defects◦ Requires the use of certain tools and techniques

Intense competitive pressures – especially from rapid globalization.

Greater consumer demand for high quality products and services, little tolerance for failures of any type.

Top management (and stockholder) recognition of the high costs of poor quality.

The availability and accessibility of large data bases and the increasing ability to explore, understand, and use the data.

Sigma Level

Cost of poor quality versus Sigma level

Motorola is known for its cool cell phones, but the company's more lasting contribution to the world is the quality-improvement process called Six Sigma.

In 1986 an engineer named Bill Smith, sold then-Chief Executive Robert Galvin on a plan to strive for error-free products 99.9997% of the time. It is the origin of ‘Six Sigma’.

Inventor of Six Sigma

Motorola saved $17 Billion from 1986 to 2004, reflecting hundreds of individual successes in all Motorola business areas including: ◦ Sales and Marketing ◦ Product design ◦ Manufacturing ◦ Customer service ◦ Transactional processes ◦ Supply chain management

Six Sigma at Motorola

“First, what it is not. It is not a secret society, a slogan, or a cliché. Six Sigma is a highly disciplined process that helps us focus on developing and delivering near-perfect products and services”◦ Saved $750 million by the end of 1998 ◦ Cut invoice defects and disputes by 98 percent,

speeding payment, and creating better productivity

◦ Streamlined contract review process, leading to faster completion of deals and annual savings of $1 million

DMAIC Steps 1. Define

Identify projects that are measurable Define projects including the demands of

the customer and the content of the internal process.

Develop team charter Define process map

1. Define 2. Measure 3. Analyze 4. Improve 5. Control

16

DMAIC Steps 2. Measure

Define performance standards Measure current level of quality into Sigma. It

precisely pinpoints the area causing problems. Identify all potential causes for such problems.

DMAIC Steps 4. Improve

Screen potential causes Discover variable relationships among causes

and effects Establish operating tolerances Pursue a method to resolve and ultimately

eliminate problems. It is also a phase to explore the solution how to change, fix and modify the process.

Carryout a trial run for a planned period of time to ensure the revisions and improvements implemented in the process result in achieving the targeted values.

Monitor the improved process continuously to ensure long term sustainability of the new developments.

Share the lessons learnt Document the results and accomplishments of

all the improvement activities for future reference.

Methods for Generating Ideas

Brainstorming

generate a free flow of idea in a group of people

Quality circles

Group of workers who find ways of improving Interviewing: Benchmarking: Measure against best 5W2H:

what, why, where, when, who, how, how much

31

Team approach◦ List reduction

Choosing a movie with friends on a Friday night◦ Balance sheet

Choosing an apartment to stay, pros and cons of each option

◦ Paired comparisons Eliminate alternatives by comparison

Quality Circles

32

Identify a critical process that needs improving

Identify an organization that excels in this process◦Not necessarily from the same industry

Contact that organization◦Confidentiality is important

Analyze the data Improve the critical processBenchmarking numbers is much more

common than benchmarking processes
